There was a further furious burst of cerise light and then the impression of almost invisibly quick motion high up, as though the corridor ceiling itself was rippling. Then the eSuit just turned the lights off; everything went completely dark while sound and blast-fronts seemed to detonate everywhere, pummelling her body from every side.

“Up!” Berdle shouted through her earbud. The suit helped her stand, she gripped the avatar from behind with three arms, brought her legs round his at the knee, made sure the shoulder bag was at her hip with her remaining hand and then put that round the avatar’s body too. She could see again. The corridor was full of light, both white and pink.

Then something seemed to erupt from Berdle’s chest and they were both flung away from the corridor and through the shallow alcove and into the lift shaft.

Cossont experienced what felt like the start of her head getting ripped off, then somebody slammed a sledge-hammer the size of a ship into her back and she blacked out.

Awake again; sore-headed, sore-backed, aching all over. She seemed to be still on Berdle’s back, looking over his shoulder through a ragged, dusty gap across the elevator shaft to the doorway on the far side. Through the smoke and dust there, a thing lumbered like a bad dream of a man; massive, reverse-kneed, arms thick with weapon clusters, saucer-headed, it stood, straightening a little, seemingly looking straight at them. If the little knife missile’s frontal attack had caused it any damage, it wasn’t visible. Cossont didn’t recognise the model; frankly it looked retro. Something rotated on its chest.

Then – silently, because her hearing didn’t seem to be working properly – another explosion seemed to go off just above the part of the shaft she could see, and debris rained down, falling past and showering into the depths. A man in a bulky glittering suit and holding a large gun, also seemingly made of mirror stuff, came floating down, as though sitting in an invisible chair. He looked very relaxed.

Cossont looked around. She and Berdle seemed to have been blown through a wall and into a storage area; everywhere she looked in the dusty gloom she saw towering stacks of shelves full of pale boxes similar to the one that had held the glittering grey cube with QiRia’s mind-state inside. They had ended up crumpled together in the remains of a set of shelves, half lying, half held standing by the twisted debris around them.

A couple of the pale, half-metre cube boxes came tumbling from somewhere overhead, bouncing and clattering down to join the jumble of debris already covering the floor. The combat arbite illuminated each of the falling boxes in turn with a thin beam of laser light from its weapon clusters, but let each fall and bounce without firing at them.
