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.
