The map of the station which the Legate had already obtained from the sleeping man’s aug precisely located the oxygen store but, even more cautious now, it took the entity some time to reach that place. It waited until others opened doors ahead of it, then turned on an internal gravmotor to bring its weight to zero and used sticky fibres on its feet and hands to propel itself along, just in case some search program should run through the station’s gravplates. It avoided using drop-shafts for similar reasons. The double doors to the oxygen store were heavily armoured—designed to contain any explosion occurring inside. The forensic AI had probably chosen this place to contain the evidence because such stores were generally no longer used—station and ship oxygen now being supplied by machines that split carbon dioxide and merely needed to be emptied of blocks of carbon, and bottled gases for suits being compressed by the suits themselves while aboard the station.

The main doors were multi-locked, but the door of the adjoining storeroom was not. The Legate slipped in there and drilled through the dividing armoured wall. Good thing it chose this route because it soon found inert gases filled the oxygen store, which also doubtless contained detectors to monitor their mix. It injected nano-optics and through them focused on an upright chainglass cylinder containing pieces of blackened memory crystal locked in a web of plasgel. Certainly a recording of everything they contained now resided inside the forensic AI, for the crystal was packed in readiness for transportation to some other evidential cache. The Legate now widened one hole through the wall and extruded from its palm a larger diameter cord packed with nanotubes which it could contract and stretch at intervals of a half inch to guide itself to its target. The cord oozed through the hole, stretched down the wall and groped across the floor towards the chainglass cylinder. Fortunately the cylinder’s end caps were of a thick plastic it could easily cut through by using diamond saws the size of skin cells. Once inside the cylinder the cord frayed into thousands of nanotubes and spread like cobwebs. The Legate connected, injecting power or, where required, light, and began copying the stored data.
