Observations and Assessments

March 10, m0039, continued

And so the team are on their train, in a carriage temporarily defined as EU territory, for a twenty-hour journey. Actually, the trip is going to be divided in two; once they reach a stop on the edge of more densely inhabited territory, they're booked to transfer to a sleeper car. Meanwhile, this two-carriage train picks up only a few more passengers - Chinese colonists, only one of whom decides that a carriage occupied by a bunch of foreigners, one of them a Felicia who's nursing an automatic weapon, is preferable to one occupied by a group of large gentlemen whose manner screams "Chinese government agents" (and even he sits as far from the group as possible).

Just moments before the train reaches the stop where they're due to change, Jianwei efforts in preparing reports for the embassy are interrupted by a call over the Web. The caller speaks as though she knows him, and identifies herself as "Diana D'Ollio".

"Oh yes," says Jianwei, guessing that this is the bartender from the elevator car, "I've been thinking about you..." Which is no more than the truth; however, he asks her to call back in ten minutes, by which time he's able to chat as he eats takeaway Chinese food in the sleeping compartment.

It turns out that her software agents alerted her to a report appearing on a technological problems board; wildly misbehaving hoppers aren't exactly common on Mars, and the incident earlier that day is sure to draw attention - she's merely got in first. She was quite impressed by the video footage she found, and is politely amused by Jianwei's responses to her probing. (Well, politely by her standards. "Oh yes - you're government scum, not corporate scum, aren't you?") She knows some basics that the team also picked up - that the hopper, which had only recently arrived at the maglev stop, was the property of a small hire company with rather obscure ownership, now that anyone checks. The software and software-hardware combination (supposedly) involved are being investigated, but no other anomalous behaviours seem to showing up so far. She suspects that there's more to be found.

"I don't suppose that you can give me anything else to look up while you decide what you can tell me?"

"No," Jianwei replies, "but do check the news for the last 36 hours."

"Okay. That's not just a distraction for the next six or twelve, is it?"

"I don't know."

"Fine, okay. By the way, do bear in mind that not all of my colleagues are as subtle and polite as me..."

She ends the call, and the train journey continues, with the train stopping occasionally for other passengers. Dr Vartex explores the benefits of his new part-electronic condition, turning his hearing down so as to sleep more easily. But as everyone settles in, the unsleeping Vajra notices one passenger, apparently confused and in the wrong carriage, pausing for oddly long outside the group's compartment. He puts some surveillance dust out through a ventilation vent, and is pleased to determine that there are no obvious booby-traps or weapons outside; however, when he follows this up with a bug-hunter swarm, he does find some other surveillance dust. So he sends a surveillance swarm further afield, into the carriage where the "lost" passenger is now sitting, and manages to identify him and acquire a decent video image. Running this through a facial recognition system and accessing a few public databases achieves a quick success; this is a known professional freelance reporter. So Vajra leaves messages with his colleagues' AI aides

March 11, m0039

When the organic team members awake, they all consult silently and decide on a policy. Florence lends Vajra her cleaning swarm, and he uses that and his other resources to locate and gather up the dust that's supposed to be watching them. They put it in a disposable cup, to be left in the compartment when they depart.

When the maglev train eventually reaches Port Lowell, Dr Vartex receives a message from "some people he knows", and announces that he's going to have to leave the others now; somebody to whom he evidently feels obliged to respond has called him in for a debriefing. The others bid him goodbye and head to the embassy, where Colette Schmidt calls them all in for a meeting in person. Once they're all seated and basic courtesies have been observed, she gives an invisible signal, and one whole wall of the room turns into a viewscreen, showing a virtual space that is designed to look like an extension of the office. This space holds one chair, which is occupied by a figure - clearly an avatar, not designed to look entirely realistic; a man all dressed in grey, with his grey-tinged face partly in shadow.

Schmidt introduces this as "Mr Grey", a representative of certain agencies who've been assisting with background investigations regarding recent incidents, and then hands things over to him. Mr Grey nods and begins to talk.

First, he apologises for any mistakes on the part of his organisation that may have caused or exacerbated the team's recent problems. It's clear that they became mixed up in a complex situation, made worse by what was probably sheer coincidence in that they found themselves in company with Dr Liang. Anyway, it would be useful to know more, so "appropriate people" have been trying to extract more information from the SIA, who have been slow to respond; it seems probably that they've been escalating questions of need-to-know right back to Earth orbit. Still, they've released a little more now.

So the EU now has a file on "Quipu", although they aren't necessarily sure that it exists as anything more than a codename for some temporary operation, or perhaps just a piece of disinformation. There really isn't much to go on. The betting in European circles is now that, a year ago, the SIA determined, through what the EU thought was an exchange of routine information, that Dr Vartex was on good terms with British military intelligence, and used the information that they had about him to lend them weight when they requested a private chat with him, out in the desert. However, "Quipu" (if it exists) must have spotted that something was going on, decided that having someone with potentially hostile allegiances actually working in the middle of its operation at Nova Iquitos was dangerous, and chose to eliminate this potential threat by a brutally direct method.

After Dr Vartex was saved for uploading by the Chinese medical team, Quipu must have decided that he was no longer a threat, or that attacking him in a Chinese hospital installation was too dangerous. Hence, it left him alone there, and was evidently slow to respond when he and the team began investigating his murder. The team then became entangled with Quipu's countermeasures against the problem posed by Dr Liang, and in the end, after they helped her work, it may simply have panicked or turned downright malicious. The attack with the hopper may have been a desperation measure, or an opportunist attempt to remove both the immediate threat of Dr Liang (and her collected samples) and a possible hostile agent in the person of Dr Vartex - or both.

In any case, it failed, and with Dr Liang under Chinese government protection and the EU prepared to make it clear that attacks on the team will be investigated strenuously, the threat is hopefully now over. Anyway, Mr Grey thanks everyone - and the wall screen switches off.

Colette Schmidt has one or two things to add to this. It seems that Dr Vartex is probably being checked over by his old military superiors, who can't be entirely happy that his brain scans have been in Chinese hands for a year - but she's seen his record, and while he had routine military clearance, there was nothing in his past (that she can discover) that was either deeply secret or of great interest to the Chinese (or his scans would perhaps have been pulled out of Chinese hands much sooner). The current "debriefing" will presumably include tests and checks to make sure that he hasn't been edited; if those don't find anything, though, it's unlikely that the military will be entirely sure about him.

However ... Schmidt is pleased to be able to say that she suddenly seems to have acquired a little more funding for the consular services team project, somehow. Hence, the team can now add one more member - and she wonders if the existing members would mind if that new member was in fact Dr Vartex. After all, he's an EU citizen, a medical doctor with military experience; it might be hard to find anyone better.

The team agree happily enough, and so the decision is formalised; Dr Vartex will be asked if he'd like the job. Then, Jianwei raises one more matter; the contact from "DD". The main question is how much they can release to her; he thinks that she could be a useful press contact, and he'd rather not antagonise her; on the other hand, the Nova Iquitos affair presumably rates as at least somewhat secret. He and Colette Schmidt review the matter, and she gives him permission to admit to some elements of the incident, and perhaps to hint at a little more - but mostly, he should be careful. He's going to have to be cagey if he speaks to "DD" again, while playing matters by ear.

From Above and Below

March 10, m0039, continued

Back at Nova Iquitos, Dr Vartex receives a couple of messages. One, from the E.U. Martian Medical service, is simply a request for him to monitor Florence's psychological stability - they're aware that she's used live ammunition recently, and this sort of thing causes them concern. The other is from his contacts in the intelligence community, who say that they've been attempting to follow up some issues of concern to him, and have come to the conclusion that the SIA were up to something a year ago, and that they may well have sought to draw him in for some reason; they had access to enough E.U. recognition codes that, yes, a call from them might have caused him to divert his hopper on that crucial day. Meanwhile, Vajra uses available optical equipment to examine the microbots it salvaged from the snakebot's load, cross-referencing what it can determine about the design and construction with Web research. While the results aren't conclusive - whoever built these things made intelligent efforts to cover their tracks, and there's certainly nothing as incriminating as a serial number to be found - Vajra's best guess is that these things were constructed using the kind of equipment and technical references most usually found in TSA territory.

Meanwhile, in the rover, Jianwei has been composing a report for the embassy, summarising his view of recent events and including a recording of the recent anonymous message conference, all flagged for the ambassador's personal attention. Among other things, he's concerned that if somebody - presumably "Quipu" or some other TSA agent of influence - is playing tricky memetic games here, they may switch from the previous line to a claim that the Nova Iquitos researchers are the victims of sabotage by another faction - and while the E.U. aren't the obvious people to set up as the villains in that case, anything is possible.

Then, as the party in the vehicle arrives at the third oasis, a Web conference call comes in for Jianwei, Dr Vartex, and Vajra. Jianwei remains in the vehicle to deal with this as Florence escorts Dr Liang, who starts taking samples. It seems that the Ambassador Schmidt has been alerted to events around Nova Iquitos (not least an explosion) by Quentin, and has seen Jianwei's interim report. Hence, she's been pursuing matters with some energy, passing requests for more information on to appropriate contacts. "They pursued the matter further, and apparently made contact with some ... supposedly helpful acquaintances of their own. And do you know what they received in reply?"

Jianwei ventures guesses along the lines of "flat denial".

"Not even that, in fact, Mr Chen. They have been told absolutely nothing. One might almost think that the SIA were embarrassed. Our own contacts seem quite unhappy with them.

"Can you hear a buzzing sound at your end, Mr Chen?"

Jianwei, who can hear no such sound in the vehicle, says as much.

"Well, that is strange, because that is what one usually hears when one has kicked over a hornet's nest. Oh, and some other people are apparently concerned that Ms Adele has been using live ammunition.

"I have come to the conclusion that it might be wisest if we were to extract you from that situation there. I will open some back channels to the Chinese, but you had best see what Dr Liang wants for herself - but do help her to leave if she wishes. Anyway, I've somehow suddenly acquired the budget to send you a couple of rented hoppers; I'll leave it up to you how you use them."

The call ends, and Jianwei determines that the hoppers will arrive at Nova Iquitos in a couple of hours. The best option seems to be to use then to travel to the nearest stop, and then return home on the maglev. So he speaks to the others, including Dr Liang, about how they should handle matters. He's not going to disobey the instruction to withdraw from the area, and while Dr Liang would like to take more time to conduct tests and so on, he has little difficulty convincing her that it might be safest for her to depart as well. However, the group at the third oasis does take the time to collect a few more samples and to conduct a brief examination of the soil around the site. Dr Liang concludes that this site too has been seeded with fertiliser, albeit slightly less than the first two - a bit of variation in the results would doubtless help avoid having them look too suspiciously uniform - and there are some signs of soil disturbances that might indicate a snakebot coming and going. However, these last are in the direction of a fourth, nearby oasis, and not of the first two; it's a fair bet that there's at least one more snakebot out here somewhere, and possibly a couple.

So the team then mounts up on the rover and heads back to Nova Iquitos, arriving at about the same time as as the two rented hoppers sent by the embassy. They speak briefly to the Peruvians, warning them that there may be two or three more dangerous snakebots out there around the other oases. Then they quickly load their luggage into the two hoppers, instruct their rented rover to take itself back to its base, and take off, with Florence and Jianwei in one (Florence actually flying it, to keep in practise), and Doctors Vartex and Liang in the other, with Vajra riding in the luggage compartment, patched into the on-board computer system and the craft's sensors.

The actual flight to the nearest maglev halt goes uneventfully, and the hoppers begin an approach to its landing strip, Florence leading the way. Then, the group see another hopper rolling out onto the field, and just have time to note that it isn't responding to standard traffic management signals when its ducted fans turn to a vertical take-off configuration, and rather than make any sort of economical short take-off run, it throws itself into the air - and at them.

Florence's trained reflexes kick in, and she easily evades the attempted ramming; the hopper simply carries on, aimed at the second incoming craft, where Vajra is by now issuing instructions to the controlling LAI. This too manages to avoid the attack, and the hostile hopper temporarily loses control, hurtling off into the sky.

This gives first Florence and then the second hopper's LAI time to make hasty but safe landings, and as Jianwei hastily logs the incident for any subsequent investigators, Florence vaults quickly out of the cabin, Dr Liang is evidently unnerved and confused by the incident, and Dr Vartex works to keep her calm and get her to get away from the hopper - but by now, the attacker has turned around and is coming back. Florence springs to the cargo bay doors of her vehicle, using her implant to tell both them and her weapons case to open up as she goes. Her UAW is ready to hand, and she picks it up - it arms itself as its stock recognises her hand - and spins around in time to see the hostile hopper bearing down on her. Her implant overlays targeting data on her vision, and she fires the shotgun barrel, once.

Her explosive shell enters one of the hopper's wing-mounted ducted fans, and detonates, shattering rotor blades and damaging mechanisms. The high-tech craft handles the disruption remarkably well, but its automatic emergency stability systems cut in, and it drops neatly to the ground. Members of the group hasten over to it and hit any emergency cut-out switches they can find.

Meanwhile, however, another group of people have emerged from the maglev halt buildings and are approaching rapidly; large oriental individuals, all similarly and plainly dressed, and all with drawn guns. The Europeans turn to meet them, some with their own weapons still in hand, and there is a brief tense moment, especially as, despite Jianwei's smoothly tactful greetings, they seem uncertain what to make of most of the newcomers and highly suspicious - but their personal identity codes mark them as Chinese government agents, and it's clear that they're here to escort Dr Liang safely back to Chinese territory.

And so the two groups settle down and wait for the next train - which turns out to have two carriages, both empty. The Chinese agents take over one, and the Europeans decide that it's most tactful to use the other. Some quick administrative footwork by Jianwei has that effectively declared E.U. diplomatic territory for the duration of their occupancy, which allows Florence to keep her weapons to hand, just in case... But anyway, the group begin their long return haul to Port Lowell.

The Knotted String

March 10, m0039, continued

The Europeans first walk back to their sleeping quarters to leave Florence's UAW (which would seem tactless to take to a friendly chat about problems in science) and to explain matters to Dr Liang first. They tell her their story so far, and then head over to the main Nova Iquitos quarters, where the Peruvian scientists are gathering in the dining room.

There, Jianwei explains that the explosion was the result of an encounter with a hostile cybershell, and then tells their story yet again, starting from the point where they boarded the road train - all illustrated with recordings from their personal AIs, date-stamped and validated. As he talks, he notices Saul Fedirici becoming nervous, even panicky, while Tiberius sees that Dinah de Carneiro, while interested in the story, is becoming irritated at Fedirici, and catches de Carneiro muttering something to Fedirici about this being bad for his "public speaking work". By contrast, Maria Coronado, although startled by the whole story, seems mostly concerned to acquire a reliable body of evidence so that she can escalate the matter to her superiors (although she does become a little irritated with Fedirici's uncertain suggestions about how to handle the matter), and Kobo Tezuka simply takes a close interest in all the technical aspects of the business.

After a while, however, Fedirici drops out of the conversation, staring into space with the air of someone working in VR, and then returns to the discussion as something much more like his previous relaxed and charming self. He now seems to think that it would be best to go public with the whole problem as soon as possible, while making it clear that Nova Iquitos disowns any attempts at fraud and will cooperate with all investigations, to put the best face on the team's handling of the problem. Coronado seems happy with this attitude; de Carneiro maybe senses that he's taking charge of yet another social issue, and perhaps finds this irritating.

After some discussion, everyone agrees that a little more evidence-collection is indicated, and it is decided that two teams will set out straight away. One, consisting of Dr Liang, de Carneiro, Florence, and Jianwei, will head to the second oasis, where the snakebot was headed, to run some tests and collect some samples; the second, consisting of Tiberius, Vajra, and Tezuka, will take another look at what is left of the snakebot. Meanwhile, Fedirici will go pick up some samples from the nearest oasis and the nearby "fertiliser" dumping-spot.

The two groups are heading out in the same general direction at first, though, so they set out in company. As they are walking across the Martian terrain, a call comes in; an unnamed being requests an immediate VR meeting with Jianwei and Tiberius. They excuse themselves for a moment to take this, and drop into what proves to be a plain, featureless VR room, where they are greeted by a simple humanoid mannequin-like figure with speech patterns and mannerisms that indicate that it's a non-sapient AI. This being explains that it is delivering an automated response to pre-set conditions - a change in circumstances.

"Specifically, Nova Iquitos have just placed a pause on all their project reports, and requested that their experimental results be withdrawn from academic discussion pending an upcoming announcement."

(Subsequent checking will suggest that this was a very quick response; the pause must have been placed during the meeting just finished.)

"Given such a radical change in circumstances there, my task is to inform you that it is believed that something or someone at Nova Iquitos is the focus of attention of an entity known as Quipu. It is further believed that Quipu controls an unidentified TSA project - probably a memetic program of some kind. You may wish to proceed accordingly."

Reference to a standard dictionary shows that a "quipu" is a pre-Columbian record-keeping system from the region of Inca Peru - a system of knotted strings. As the NAI appears to have finished delivering its message, and shows little inclination to expand on matters further, Jianwei and Tiberius drop out of the meeting. They pass a quick summary of what they were told to their colleagues, and later provide a more detailed recording; Florence files it ("Hold this for me, Dougal"), and when she reviews it at leisure, is exasperated at the scantiness of the information, while Vajra, hearing the name Quipu in this sort of context, discovers that it has what seems to be a relevant reference pointer - which unfortunately leads to a blank, deleted space in its memory.

Anyway, the two groups continue on their way. Before they split up, Tiberius carefully questions de Carneiro over heshes disgruntled attitude towards Fedirici, coming to the conclusion that the latter has simply annoyed de Carneiro by being charming and socially successful, parlaying his charisma into a generally profitable career. At some point, he also researches the public speaking events that the Fedirici is apparently undertaking, finding relevant schedules on the Mars Web and trying to ascertain the sponsors and suchlike in case they proved to be relevant at a later date. The Europeans look into this further when they can, and note that the talks have very recently had title changes, de-emphasising the "success" of his work in favour of objective discussions of "events" at Nova Iquitos.

The two groups go their separate ways. At the scene of the earlier fight, Vajra deploys one of his surveillance swarms, and discovers four or five identifiable microbots from the snakebot's payload, while Tezuka prods around the remains of the hostile cybershell with interest, and Tiberius looks on.

The walk to the second oasis takes longer. On the way, Jianwei, reviewing the situation, sends a message asking that the rover that is on its way should come directly to this group - it won't pass anywhere near Nova Iquitos in that case. The group also draws de Carneiro out a little more regarding Fedirici, confirming the general impression that hesh is, frankly, jealous of Fedirici, thinking that he uses social skills to gain advantage in his scientific career. It seems that Fedirici is indeed becoming a minor public figure, and he or someone helping him is determined that he should look as good as possible. Jianwei has some training in memetics, and thinks that he's beginning to see a pattern here; Fedirici looks like the well-honed or well-chosen spearpoint of a serious memetic project.

At the second oasis, there's still no sign of microbot or cybershell activity, and Dr Liang begins collecting samples. She'll run a lot more tests later, when she has better facilities available, but even the portable gear she has with her can pick up traces of the planted fertiliser chemicals; evidently, this site too has been seeded, and the snakebot was doubtless on its way to clean it out. In fact, the group head out carefully in the direction of the first oasis, scanning the ground as they go, and sharp eyes spot an area of disturbed ground at a point where the snakebot, moving between the two sites, might well have been expected to burrow down or surface in the past. It will be interesting to examine the more distant sites... Which can best be accomplished with a vehicle. And so that group waits until the rover arrives. When it does, they check it as best they can, finding no signs of tampering, and set out to look for more evidence further afield.

Dinner and a Hop

March 9, m0039, continued

The Europeans return to their accommodation module to discuss their next steps. They call Quentin and arrange to acquire some IR-spectrum satellite imagery of their current location from standard civilian sources - this kind of thing is generally available for a modest fee, although a continuous real-time feed would be too much to ask for; rather, they'll get an image downloaded whenever an appropriate satellite happens to be looking this way. While this is being arranged, Vajra puts a camera on the roof of the module to try and keep some kind of permanent observation of the nearest oasis going, and runs a swarm over the module and everyone in it to check that they aren't being bugged. (He doesn't find anything.) The group also talks about next moves with Dr Liang; they decide that when their hired rover arrives the next day, they will lend it to her "as a courtesy" to help her carry as much equipment around as possible - and also have Florence go out with her as an "assistant". In fact, the point is that their rover is less likely to have been tampered with, and Florence will act as a bodyguard.

By now, dinner will be being prepared in the permanent part of the station, so the group heads that way, prepared to distract any spies among the Peruvians from what they're up to. Florence pulls a change of clothes from her luggage, and also makes suggestions about how Jianwei and Tiberius might dress; the idea is to aim for a general "naive kitty" look for herself, and smart casual for the others. Jianwei also extracts some Earth coffee beans from his luggage to take as a contribution to the meal. When they reach the dining room, however, they decide that much of this effort may have been wasted; the Peruvian scientists all seem distracted by their days' work and, while not actively hostile, aren't exactly being chatty. Still, Jianwei manages to make a little diplomatic small talk, Florence's appearance inevitably has some effect on the heterosexual males present, and Tiberius circulates, while Dr Liang is able to join the technical discussions comfortably enough. (She understands concepts such as "nitrogen micro-cycles".) The only real discovery of the mealtime comes when Florence, quietly looking in corners of the module, works out where the Peruvians store the output of their secret still.

Back in their own module, the team talk further. Dr Liang stands by the opinion that these people are honest; the manipulation of the experiments is, she is sure, being conducted by some unknown outside party. Thinking more about the matter leads Vajra to pull down some data on visitors to Nova Iquitos over the last few months, which Jianwei systematically analyses. He notices that some people who were due to come here never actually showed up, and Dr Liang is able to shed some more light on these; in one case, a laboratory accident took a researcher out of circulation for a while, and in another, an unexpected research grant from a University of Mars committee distracted the would-be visitor. Furthermore, these were people - not Peruvians, it's noted - with strong connections to the sort of online journals which have been publishing the provisional experimental results. The group's provisional conclusion is that somebody with very good connections and resources is trying to protect whatever has been done here from exposure.

Furthermore, Quentin now has a good collection of IR images for them to work with. The group look them over, searching for the sort of anomalies that would escape casual attention; Jianwei and Tiberius apply intelligence assessment training, but it's Vajra's patient, methodical processing that achieves a useful result. There's a persistent warm spot, just a little way from the edge of the nearest oasis, that doesn't look quite like a natural variation in rock surface qualities, but which could be consistent with the heat output from a fuel cell sufficient to run a small set of microbot hives. The thing is probably buried deep enough to be hard to excavate with the gear that the group have easily available, but they decide to watch it carefully.

In fact, Vajra goes out and plants a surveillance swarm in the relevant area - but the others have other concerns on their minds. The hour is getting late, and only Vajra can go without sleep. Hence, the organics in the group retire to their curtained bunks, leaving Vajra watching the swarm and real-time IR imagery, along with various other data streams.

March 10, m0039

In the early hours of the next morning,Vajra, running its periodical scans, notices that the hot spot has started moving. It wakes up the organics, and everyone quickly agrees; something is shifting at a fast walking pace in the direction of the next closest oasis. Other cameras don't show anything - whatever is involved is apparently tunneling deep in the loose soil and sand. Fortunately for the group, that makes it relatively slow; they can quickly plot a way to intercept it.

The Europeans prepare, while Dr Liang, commenting that this is presumably some kind of cybershell of unknown capabilities that may not want to be noticed, opts to stay in the accommodation module. Along with heatsuits and night vision gear, the group pick up weapons, including a double-barreled "urban assault weapon" for Florence - who spends a few moments wondering aloud exactly what sort of high-powered explosive rounds to load into its larger smooth-bore barrel. (This may be the sort of thing that persuades Dr Liang not to come along.) The group decide to split up; Vajra and Florence will attempt to track the thing, while Tiberius and Jianwei will move to the point where they think it's headed.

But first, Florence and Vajra set out to recover Vajra's surveillance swarm, then set out to catch up with the moving trace. They both have access to efficient GPS systems; Florence also has excellent night vision equipment, but Vajra lacks such gear, so Florence lends it her glasses and relies on her own Felicia eyes - which are more than adequate, given the illumination provided in the Martian night by the insolation mirrors high above. Still, they have some difficulty being sure of exactly what is where - but they catch up with the trace soon enough, and Florence moves ahead alone to see if anything is visible on the surface.

She's still blundering around a little, though, it seems - because she doesn't see the movement on the surface of the loose Martian soil until she's almost on top of it, which happens to be the moment when the tunneling cybershell surfaces, doubtless knowing that it can move faster above than below ground and thinking itself safely undetected. Fortunately, it proves to be as unaware of Florence as she was of it. As the cybershell - another snakebot, but much larger than the last, relatively unsophisticated in general design, longer than a man is tall, with a broad body - appears, she reflexively brings her weapon to bear and triggers its targeting systems; a fraction of a second later, its head rotates like a turret and it evidently sees Florence. She notes instinctively that it has three lens-like apertures, when two eyes are generally enough for a basic cybershell, which suggests that the third may be something else - and that consideration makes her complete her aiming move and pull the weapon's second trigger almost without conscious thought.

At nine metres range, many fighters might go for a centre-of-mass shot, but Florence, knowing that designs like this usually have their processor - or at least a major control node - in the leading section, and also wanting to eliminate that probable weapon, and being confident in her own abilities, goes for a head shot - and succeeds.

The large-caliber shaped-charge round rips into the cybershell, blasting it backwards and evidently causing massive system failures. Florence, however, remembers what happened last time she helped disable a hostile 'shell - and this one is much bigger. Still moving on instinct, she twists round and jumps, covering a dozen metres in a single leap thanks to the low Martian gravity - and landing close by Vajra, who is just coming up to see what's happening.

"What's the problem?" Vajra pulses to Dougal.

"Self-destruct charge," Dougal sends back, having caught Florence's subvocalisation. Vajra drops to the ground.

The grenade planted in the snakebot does indeed choose that moment to detonate, but Florence and Vajra are safe enough - the blast is only a little more than a loud noise and a wave of heat at this distance, and no shrapnel reaches them. Still, the explosion is detectable some way across the desert. Jianwei and Tiberius call immediately; reassured that their colleagues are unhurt, they set off at a fast trot to help investigate on the spot. Calls also arrive from the research station; Jianwei declares that no one is hurt, and promises more explanation soon.

Once everyone is reasonably confident that the cybershell is no longer a danger, the group sets to work investigating it. It's a pretty basic design - while they can't pin down its exact origins this time, this type of snakebot chassis is fairly standard, and the brain, body construction, and power/motor and weapon systems are all either standard fabrications or off-the-shelf purchases. (The weapon was in fact a dual dazzler/high-power laser unit.) It wasn't overly robust, although it was quite heavily built; much of the structure consisted of a set of integral microbot hives. The swarms in those seem to have been fairly thoroughly cooked in the explosion, although Vajra makes a mental note to return to the spot tomorrow and search the surrounding area for less damaged microbots that may have been thrown outwards by the blast; that will be easier in daylight.

By now, the staff at Nova Iquitos are calling; they've noticed that explosion, and although they've been reassured that everyone is well, they're naturally curious, at the very least. So once they Europeans have collected as much data as they can, Jianwei calls the Peruvians back. He decides that it's time for a talk with them, and they're going to have to know that there's something strange and dubious going on here. Dawn won't be very long now; he asks them to gather for a meeting in their base shortly.

And so the European team gathers up as much evidence as they think they can usefully carry, and sets out back to the mobile station.

Shifting Sands

March 8, m0039, continued

Aunty loads up a forensics skill set program, and under her direction, Jianwei begins carefully examining the snakebot, as the various AIs present scan the Web for relevant information. It's a pretty standard design; technically, some components may be covered by patents, but fabricator blueprints for things like this are easily available on sources such as the TSA Web. (In fact, Dougal finds what may well be the blueprints for this exact design on a grey-area site, despite Florence's attempts to tell him that he shouldn't look in such places.) The head section has been pretty much completely destroyed; the brain chip was evidently a standard-over-the-counter unit, but has been fried too thoroughly for any sort of identifying code to be recovered, let alone any software. The snake had quasi-realistic fangs, and by borrowing some analysis equipment from Dr Liang, the party concludes that it was probably loaded up with some kind of synthetic drug or toxin for use in combat; it also had small tanks further back along the body, which could have held the bacteriological cultures that ended up in the module's water supply. This, it's clear, was definitely the sabotage agent here. The motors, moving parts, and body shell look to have been constructed and assembled in a minifac, and the blueprints used prevented it from including any sort of serial numbers or ID codes.


The Europeans decide that this was most likely an attempt to delay Dr Liang, rather than being aimed at them; while it's just possible that the snakebot was inserted on the road train after Quentin booked them onto it, the timescales involved were tight, and the attack method was very poorly chosen if they were the intended victims. But if Harvey and Dr Liang had been the only people on board, and had fallen ill, Sundance would have turned back to a different human community. As yet, though, they can't say with any certainty why anyone would have done this; Dr Liang has no idea - she's just an academic planetologist. Harvey comments that he picked the passenger module up at Heze, a Chinese community which is large enough to have rental minifac facilities available.


In any event, given that the plan was most likely to cause a delay, the party decide to move on as soon as they've finished checking the road train for other sabotage attempts as best they can. (They don't find any, although that's only a moderate reassurance, given that they don't have professional-grade search gear, and state-of-the-art sabotage techniques can be very easy to hide.) Harvey says that he can increase the speed of travel a bit if anyone thinks that it's a good way to get back at the people who poisoned him, but the time that's been lost or that might be regained is pretty trivial compared to the length of the journey in total, so the group decides not to take the small risk involved. Still, they retire to sleep as Sundance drives on through the night.

March 9, m0039

The next morning, after an uneventful night, the group goes over the details of the road train's schedule with Harvey some more. Given the arrangements at the rental company depot at Heze, it wouldn't have been too hard for anyone to identify this as the module he'd be using, or for the snakebot to get aboard. He's carrying some goods and supplies for Nova Iquitos - passengers aside, this is a pretty routine run for him... No one can see much more to chase up at this point. The Europeans do wonder who might benefit from falsification of good results from the oasis tests; it would make the Peruvian scientists look good, or at least lucky, of course, and by the time their work proved less useful than this implied, the benefits might have been harvested. But is all this enough to justify fraud and murder? Jianwei also looks at the bodies sponsoring Dr Liang's trip, and checks some background; while they're mostly international academic bodies and journals, he's somewhat puzzled to note that there may be more American influence involved than he might have expected.

The road train reaches Nova Iquitos around midday. The mobile station consists of a set of movable living and laboratory modules, arranged in a loose ring a few hundred yards from one of a cluster of ecological oases. The current inhabitants are the core staff only - as Tiberius can attest, the place sometimes has other temporary staff, usually visiting academics, but for now there are just four people present: Dr Maria Coronado, the station director, Saul Fedirici, the assistant director in charge of research (i.e. the one in charge of actually doing science), Dinah de Carneiro, the systems controller (responsible for running the scientific systems from day to day), and Kobo Tezuka, the chief technical officer (i.e. the hardware maintenance specialist). In addition, anyone spending time on the station will end up making the acquaintance of Burbuja, a management LAI running on its local network. Tiberius remembers Coronado and Fedirici (and Burbuja) from his previous time on the station; de Carneiro and Tezuka are new, as other staff have rotated out in the last year. He himself hasn't been replaced; admittedly, one small station has limited use for a fully trained doctor, especially given the sort of software assistance available to anyone in a medical emergency - he spent a lot of his time previously assisting with biological research and being there as a reassurance for visitors.

Coronado greets the newcomers warmly - she and Fedirici seem genuinely pleased to see Tiberius again, and any cultural prejudices notwithstanding, seem to be prepared to treat a ghost as a person, and the same person as they previously knew. Tiberius recalls her as a brisk, businesslike character, but she's apparently in an outgoing mood today, happy to invite all the visitors (including Liang and Harvey) to lunch. Still, it's Fedirici who perhaps ends up doing the most talking over the meal; Tiberius remembers him as a charismatic character who always tended to act as the research team's spokesman and guide for visitors.

On the European side, Jianwei takes the lead as usual, and is quite open about the reason for the visit, explaining that Tiberius's death wasn't an accident but apparently involved a deliberate attack. The Peruvians appear genuinely shocked at this, and profess themselves anxious to help with the investigation. Nor do they seem too hostile to Dr Liang, although the fact that she's undeniably here to check up on their work could make for social difficulties. During and after lunch, the conversation breaks up into smaller groups; for example, Vajra falls into conversation with de Carneiro, who is an asex; Vajra feels a kinship with the disavowal of human passions that this suggests. However, Jianwei for one senses that de Carneiro isn't entirely lacking in emotional issues; there's a slight sense of irritation directed towards Fedirici, who maybe gets the lion's share of credit for the research work being conducted at the station, simply because he talks about it best.

Meanwhile, Harvey heads out once more on his way after unhitching the rented accommodation module, which is soon linked up to the station's power supply, and Dr Liang begins setting up her equipment. As the others talk to the locals, Florence becomes bored and decides to take a walk and a look around the local scenery. Inevitably with her,  this involves climbing some of the local rock formations, which she manages with ease, thus gaining a good view of the whole area.

It's from this position that she notices something odd - perhaps it's just a trick of the light, but there seems to be a sense of movement on the relatively smooth surface of the nearby oasis area. She continues watching for a while, and records what she can with the integral cameras in her night vision glasses, then calls the others. Vajra analyses her recordings, and tentatively agrees with her assessment; there are subtle shifts in tone or texture, likely only visible from above and from a distance. As soon as they can, the other three Europeans get away from the station buildings and head for the oasis, while Florence climbs down and extends her "stroll" towards the next nearest such site - a few miles away, but easy enough to reach.

There's not a lot to see at the nearest oasis, but now that they know what to look for, the newcomers provisionally confirm the impression yet further - there's maybe something under the sand, operating over a wide area - probably a cyberswarm. Vajra drops a surveillance crawler swarm and sets it watching, while the teams' AIs load tracking skill sets. With these, they pick up signs of something maybe having surfaced just outside the area of the ecological test; following the trail, they decide that some specific substance is being extracted from the oasis and dumped just out of sight of it. They collect samples as best they can, and head back towards Nova Iquitos.

On their way, a figure comes in sight coming the other way; it's Dr Liang. She's interested and concerned to hear what they have to say; all this is beginning to look like a bad case of academic chicanery, which isn't something that she expects or likes to see. She's also puzzled by another matter. She's received a message through private communication channels that she thinks must have come from one of her sponsoring bodies, but which is unclear - it lacks headers or signature. What it says, though, is that she can probably trust Tiberius.

Which bemuses Tiberius and the other Europeans as much as it does her. But anyway, they hand off some of the samples they've collected; she has the best scientific kit here, after all. She runs a quick analysis, and confirms their suspicions; these look like extra nutrients for the bacterial/fungal cultures in the oasis. Again, this looks like a fraud being hastily removed from view; given that she hasn't been hurrying to set up her tests, she might well have missed this material, even if she hadn't been delayed by the poisoning on the road train.

Meanwhile, Florence reports by radio from the second oasis; she isn't sure, but she doesn't think that there are any strange soil movements here. Presumably, the clearance is being conducted first at the place where Dr Liang could be expected to look first. And Vajra continues to run some subtle surveillance at the first oasis, while the party wonders if they could somehow locate, say, the clean-up swarm's power supply - probably a buried power pack somewhere.

The Venom of the Serpent

March 8, m0039

Back on a maglev train, the group discuss the next phase of their investigation. First, though, Tiberius mentions that he has received a Web message from an acquaintance in Military Intelligence, which among other things, notes that, so far as that organisation has been able to establish, the hospital where he was uploaded is run ethically, and there have been no signs of the Chinese "Bureau" agencies taking an interest there lately; the privacy of his scan has probably not been compromised. Perhaps of more immediate importance, the agency has noted Tiberius's activities and concerns since his restoration, and having checked its own data sources, it has reason to believe that American Space Intelligence Agency operatives were active in or near the same part of Mars when Tiberius suffered his accident - although the SIA is unwilling to explain what exactly they may have been doing there.

This leads to a little discussion in itself. It seems unlikely that the SIA would be responsible for shooting down Tiberius's hopper - while they and the Europeans sometimes work at cross purposes, the two factions aren't actively hostile - but it's possible that Tiberius diverted to meet an SIA agent, although he can't suggest any reason why he'd have done so. Anyway, it's more information to consider. The group also discusses how to handle the visit to the Peruvians, although Florence rapidly loses interest as the planning grows more detailed and conditional.

As they travel, they are also contacted by Quentin, who tells them that he's arranged transport for them to the Nova Iquitos site. It's been hard to find a vehicle to rent - they're heading into more sparsely populated territory - but he's been able to book passage on a cross-country road train. However, the group aren't entirely happy with this; it will leave them on site with no transport of their own if they suddenly find that they have to leave in a hurry. Quentin is apologetic, but vehicle availability is a problem... Eventually, though, he says that, if they can avoid getting into trouble for twelve to twenty-four hours or so, he can arrange for a rented rover to drive itself to the site and make itself available for them after that time.

Eventually, the maglev train reaches the team's stop - which proves to be a halt rather than a station. They disembark, and determine that they have a couple of hours to wait before the road train arrives. Sitting around on their luggage proves boring, so they decide to take a walk and look at the local rock formations.

After a little while, they hear another maglev arrive from the other direction and stop, and Web tags indicate that someone else has disembarked. They contact the new arrival by radio, and discover that it is Dr Ming-Mei Liang, a Chinese planetologist, who is meeting the same road train; when they say what they are doing, she asks to patch through to their cameras, and promptly spends ten minutes telling them about the science of the rock formations. They return to the halt, and discover Dr Liang sitting with a large travelling case; however, she says that she isn't packed for a long visit - this is simply her professional equipment.

She's happy to talk, and explains that she too is visiting Nova Iquitos; indeed, it emerges that it was her who arranged for the road train to come this way and to have a passenger module installed - Quentin then got lucky on the party's behalf, as the module has enough spare capacity for them. Dr Liang, it seems, is heading this way to perform some research. Nova Iquitos have recently been reporting some much better-than-expected performance by the ecological "oases" they monitor - gene-crafted bacteriological/fungal cultures planted out in the Martian desert, part of the terraforming process. This has attracted a certain amount of attention, as it would be good news for the terraformers if these results are accurate, but they do seem very good, so it seems like a worthwhile idea for an impartial scientific investigator to review them in situ.

The road train arrives, and proves to be owned and run by a single driver - an organic human, not an upload like some Martian truckers. This is Harvey Hernandez, an American citizen who wears a Stetson over his heat suit and speaks with a definite drawl. Hernandez seems amiable and spry enough, but some of the party decide that he has something of the look of an elderly man; indeed, he eventually lets slip that this is his second career - he spent forty years working as an accountant. He's a rejuvenated eloi, and a recurver.

The PCs and Dr Liang load their luggage onto the road train and climb into the passenger module. This proves comfortable enough, with sufficient bunks for all of them (with sound-deadening curtains), giving Florence a chance to catnap a little, and also a fully functional miniature kitchen. It's docked immediately behind the train's tractor unit, with a linked airlock, and once the whole assembly is underway again, Harvey leaves the driving to his personal AI, Sundance, and comes through to join them and talk. He doesn't get company on many trips, and while this may not worry him, he's happy enough to have someone to chat to.

The travellers swap stories of Mars and elsewhere, and get on well enough, although Harvey's taste for Country and Western music on the sound system might become wearing (Florence decides that she likes it in small doses). Eventually, the group call up dinner; Harvey's systems specialise in Tex-Mex cookery, and can produce a passable taco if one allows for the possible provenance of the "meat". However, as the travellers eat and drink, both Harvey and Dr Liang look a little oddly at their drinks, although the Europeans, their taste buds adjusting to unaccustomed spicing, don't notice anything. Harvey steps over to the recycling system maintenance panel and begins checking diagnostics as all the organic travellers begin to look a little queasy.

Harvey sits down looking distinctly unhappy before he can complete the maintenance checks, and both Jianwei and Florence are feeling fairly seriously unwell by now; however, Dr Liang didn't eat or drink as much when she noticed the odd taste, and Tiberius has the benefits of a boosted liver, installed in his original body during his military career and carried over in the spec for his bioshell, which counteracts the toxins without difficulty. He considers the diagnostics available from his computer-body interface systems, and recognises the problem instantly; a bacteriological infection that sometimes occurs in some types of water recycling system. It's supposed to be a rare problem, easily eliminated by competent maintenance, but sometimes people do get sloppy.

As Florence takes to her bunk and then grabs a bowl more or less in time (leaving her cleaner swarm with a little work to do on her fur later) and Jianwei and Harvey sit groaning, Tiberius checks the vehicle's medical supplies and his own portable kit, and comes up with a reasonable set of treatments. Then he tells his AI aide, Vediovis, to load the system's maintenance manual, takes Harvey's place at the panel, and works out how to purge and reset the water recycling system. By now, Sundance is asking if it should turn the vehicle back towards the nearest community with medical facilities, but this is vetoed all round; Tiberius's treatments seem to have been effective, and there's some sense among some of the travellers that this may not be as much of an accident as it looks.

So Vajra sends a swarm into the interior of the module's life support systems, using it to look for anomalies - and finds one. Something - larger than a swarm element, small enough to fit in the access spaces - moves quickly across one microbot's field of view. So Vajra pulls up more schematics and consults with Jianwei, who has an eye for tactics. Then, he and Tiberius begin to move and dismantle some elements of the system, isolating their target. Eventually, they give it no more places to hide - and they are ready when the miniature snakebot pops into view.

Florence fires first, but the snakebot ducks away from her tangler shell, which merely makes a mess on wall. However, the thing is unable to evade Jianwei's electrolaser bolt, and lies twitching and writhing for long enough for Florence to score a clean hit with a second tangler shot. Then Tiberius's army background kicks in, and he suggests that everyone takes cover - he's trained to expect miniature cybershells to incorporate self-destruct systems. Everyone follows his lead, with varying degrees of agility and haste, but the snakebot takes a while to recover any sort of control, and any autonomous self-destruct systems it may include evidently aren't set too sensitive. Eventually, Vajra decides that he can afford to take a risk, grabs a cushion from the seating, and tries to use it to screen the effects if the snakebot does explode. He's still trying to get the cushion in place when it does explode, in fact, but it only carries a small charge, and the tangler covering it effectively absorbs the blast.

There are some parts of the snakebot left intact, though; it may be time to try some ad hoc forensics.

A Handful of Dust

March 4, m0039, continued

The team spend the rest of that day sorting out the gear that they might need for this investigation. Dr Vartex has received a set of packages, routed by Quentin at the embassy, containing his personal effects from both Nova Iquitos and his old rented flat; the rest of the team note that this package has a security seal, suggesting that some of the contents may be legally controlled in some jurisdictions - probably nothing very worrying, but it seems that the doctor may own a sidearm or two. He reports that, by the best of his recollection and available records, there's nothing of his obviously missing or showing signs of tampering. That aside, the team apply some of their expenses budget to acquiring or (mostly) renting survey equipment, which fortunately proves to be fairly widely available - New Shanghai is a major city on a frontier world, not very far from a university, after all. Specifically, they pick up a lightweight ground-penetrating radar system, a small excavation cybershell, and an excavation cyberswarm to go with Vajra's survey swarms.

March 5, m0039

The next day is mostly occupied by a long maglev ride to the small Chinese outpost where a hotel booking and a rented rover will be waiting for them. They take the opportunity to catch up on paperwork and correspondence - Florence has a set of lessons from her continuing education in human society to deal with, and Dr Vartex has a slew of messages welcoming him back to the land of the living and expressing best wishes (and maybe one or two making it clear that old acquaintances regard him, not as his former self, but as a technological abomination). They also continue to talk over the question of what and who might have been behind Dr Vartex's death; their current preferred guesses involve some kind of smuggling operation.

At the stop, they check into one of a widespread chain of capsule hotels, and then look around. This is the place where the medical team who saved Vartex's life were based; it might perhaps be worth trying to locate these people, if only so that Vartex can thank them. Unfortunately, Jianwei doesn't manage to convince the clerk at the medical centre to be very helpful, but the group simply slip around the back of the site, find an employee who's willing to chat, and get the name of a bar (one of the three in the town) where the flying medics relax in their evenings. It seems that most of the team who found Vartex are still stationed here, and when Jianwei and Florence - the most sociable of the four - buy them a round of drinks and introduce Dr Vartex as "one of your success stories", they're more than willing to talk. (They too seem at heart to regard Vartex as a piece of software carrying some useful information recovered from a corpse, but as sophisticates by the standards of their society and also medics, they can still see this as a worthwhile thing. Anyway, one of them mutters, whatever the official legal position on ghosts in Chinese territory, there are rumours about some members of the Central Committee back in Beijing.) They remember that day last year fairly well - it was a dramatic sort of incident, after all - and one of them comments, when asked, that their aircraft's radar screens showed two ground vehicles more or less in the vicinity of the crash, though neither was visible at the scene when they arrived - they assumed that both were passing desert travellers who initially responded to Vartex's hopper's automatic distress call, but turned away once it was clear that the medics would get there first and be best equipped to help. The relevant sensor logs should still be available...

Meanwhile, Dougal has been mildly annoying the bartenders and some other customers who use augmented reality by running up and down the bar. Once Florence has persuaded him to stop and apologised for this, and also finished politely fending off an unconvincing amorous approach by one of the bar's other patrons, the four Europeans retire to their four capsules in the hotel for the night.

March 6, m0039

The next morning, reminded by his AI aide, the friendly Chinese medical team member from the night before does indeed transmit those sensor logs to the team, around the time that they are collecting and loading up their rented heavy rover. Once they are underway, they're able to review this material; examining it closely with trained eyes (and both Jianwei and Dr Vartex have some knowledge of intelligence analysis), they note first that both vehicles were showing only minimal transponder response - legally sufficient, and enough to avoid suspicion from casual observers, but not very informative. They also decide that one of the vehicles was probably at the location which the hopper would have reached had it not been shot down, and that it probably never came very close to the crash site; the other, which came from the shoot-down point, was probably the one that did reach the crash, but wouldn't have had very long there before the medical team arrived. This raises the question of why that individual didn't finish off Dr Vartex while he had the chance - but even if he didn't have other priorities, he may not even have seen the body amongst the wreckage, or he may have thought that Dr Vartex looked sufficiently dead - and putting in another shot to be sure would probably have left a mess that even a careless forensic examination would have noticed. Another point to note is that both vehicles would have needed to be long-range, well-supplied types if they could loiter in that area for long without having to head for some nearby community for fuel and life support recharges (the team's own rented rover comes with a trailer to carry extra fuel for this trip), but such specialised models do exist.

Although the rover comes with a NAI that can drive it competently, Florence decides that she wants to practise her vehicles skills. Her VR training was actually for lighter models, but she manages this one adequately, and decides to train up on such vehicles - the team will doubtless use others of the same general type again in future. After lunch, Jianwei too takes a turn behind the wheel, although he has a little more trouble - the vehicle AI cuts in to offer assistance at one point.

By the end of the day, the others note that Dr Vartex is looking especially withdrawn and grim, and realise that the thought of visiting the scene of his own death is becoming a little oppressive for him. Still, he focuses on the task in hand, and everyone prepares for the task of investigation. Rather than drive over the site, they stop a mile or two short of their destination, by which time it is late enough in the day that the three organic team members decide that they should settle down to sleep after eating and some final planning. Vajra, on the other hand, simply dons a bit of cold weather protection and some light-enhancing goggles, takes a full set of cyberswarms, and sets out to prepare an initial map of the location in preparation for the next day's work.

March 7, m0039

Hence, the team are awoken in the morning by the returning humaniform cybershell, and start their day with a prepared coordinate map of the crash site and some initial imagery. They drive carefully up to the scene, which has fortunately not been too badly disrupted by weather in the past year, and set to work.

The ground-penetrating radar locates a number of additional fragments which they're able to excavate, and they contact Quentin to tell him that these will eventually be sent his way. He in reply says that he's still having some difficulty locating a fully-qualified forensic analyst who the embassy can consider entirely impartial, but he's been able to conduct some analysis himself, and he's sent high-resolution scans and images back to Earth for assessment by specialists in Brussels; so far, everything seems to confirm the missile-damage hypothesis, although the best bet then is that a shaped charge projectile was used, and it's not clear that enough chemical traces would remain after this time to establish any more about that.

Looking at the site, and using downloaded skill sets to conduct efficient searches and to perform forensic analysis of their findings, the team decide that they can provisionally further confirm this conclusion. They also think that Dr Vartex was quite lucky, in that the craft's pilot AI did a good job of moderating the force of the crash, which is why he was, bluntly, in few enough pieces when the medical team arrived that they were able to recover his brain. The doctor also looks at everything that can be reconstructed from the site, both from the Chinese forensic store and with the aid of this extra work and equipment, and decides that he is pretty sure that there was nothing substantial being carried on the aircraft for which he could not account - unless of course it was recovered at the time.

So the team next extend the area of their search out in two directions, using the ground-penetrating sensors and more downloaded skill sets to track the two vehicles back along their respective paths. This is difficult at this distance in time, of course, and they quickly lose the tracks of the person who apparently performed the shoot-down. However, working back logically, they find the place where that vehicle most likely was located when whoever was on it opened fire; the combat-trained members of the group decide that this looks like a well-planned ambush from well-chosen cover. As for the other vehicle, which the hopper was apparently descending to meet, they decide that it must have been waiting for at least a little time on that spot. However, neither left much in the way of traces such as discarded refuse; both vehicles were apparently being operated by competent professionals who knew something about secrecy. Both seem to have moved off in roughly opposite directions - east and west - evidently after the Chinese medical team showed up, although there's no hope of following their trails for very long.

By the end of the day, the group still have no idea who attacked Dr Vartex, who the other party was, or how his hopper was diverted, whether by software subversion or some other means - but they have a fairly detailed picture of the events of that day, and at least they haven't been attacked (a possibility which had crossed their minds). The next step, they think, is to follow the trail back to the Peruvians of Nova Iquitos - which means taking the rented rover back to the maglev track, moving on to a stop yet further west, and then heading out from there. In order to save time, they tell the rover's AI to take over the driving and head back along the route it now knows, with Vajra keeping watch, while the three organic party members catch some sleep in its capacious seats.

So, next on the itinerary is Elysium Planitia.
