Over a hundred and seventy people had died here, fifty-four of them when the Marineris Base was crushed by a rock fall, the rest in and around Antares Base. All the dangers of Earth were here, including overzealous enforcement, along with a whole load of new and interesting ways to expire. Though it was next to impossible to inadvertently punch a hole through the mesh fabric of an external activities suit, it still possessed plenty of seals in it that could fail. Over the years, forty-three people had asphyxiated outside the base as the result of such failures. Then there were all the odd chemical compounds generated when Martian materials were introduced into the hot, moist and oxygenated environment of the base. Before Var’s time, four people had died trying to produce viable soil from the Martian dust: a spill of water had resulted in an explosion of sulphur dioxide, and they had died inside the laboratory when emergency bulkhead doors had closed – needlessly, Var reckoned, since the gas would have affected few people beyond the laboratory itself. But, then, safety protocols had been strict for years after the first explosive decompression of part of the base complex. Other interesting ways to die included heavy-metals poisoning, some esoteric cancers solely the product of this place – one of which had killed Var’s predecessor – and suicide, which was often the ultimate choice of some who had been forced to come here against their will. Just like Var herself had been forced.

Her loping stride eating up the distance slowly brought the crawler into full view. One of its big fat tyres, she noticed, was flat, which was unusual because they would usually self-repair and reinflate. She could now see that the front screen was also broken – another unusual event, since the laminated glass shouldn’t yield to anything less than a bullet. Only as she drew closer did she see the line of holes stitched across it, and realize that bullets were precisely what it had yielded to. And when she finally reached the big vehicle, and peered through the broken screen, she saw why Gisender had stopped talking.

‘She’s dead, Miska. The fucker had her shot.’

No reply.

‘Miska?’

Var walked round the side of the vehicle to the airlock, scanning for footprints in the surrounding dust but seeing none. She paused for a moment and looked back in the direction of the base. Whoever had shot at this vehicle had done so from a distance, probably from Shankil’s Butte, which reared up from the plain five kilometres away from here, and just three kilometres from the base. Doubtless the killer had used a scoped assault rifle, which would work easily enough at that range in the low gravity here. One of Ricard’s enforcers, undoubtedly.
