He passed a pair of rest rooms, and stopped the cart. Phyllis rolled helplessly off the seat and onto the floor, moaning louder than ever. Soon she would regain consciousness, if she hadn’t already. He got out and ran over to see if the men’s room was unlocked. It was, so he ran to the cart and pulled Phyllis up by the shoulders, up and over his back. He staggered under her weight until he reached the men’s room door, then flopped her down; her head cracked against the concrete floor, and her moaning stopped. He opened the door and pulled her through it, then closed and locked it.

He sat on the bathroom floor beside her, gasping. She was still breathing, and her pulse was shallow but steady. She seemed okay, but knocked out even more definitively than when he had hit her. Her skin was pale and damp, and her mouth hung open. He felt sorry for her, until he remembered her threat to give him to security technicians, to tear his secrets out of him. Their methods were advanced, but still it was torture. And if they had succeeded they would know about the refuges in the south, and all the rest. Once they had a general idea of what he knew, they could coax the specifics out of him; it wouldn’t be possible to resist their combinations of drugs and behavior modification.

And even now Phyllis knew too much. The fact that he had such a good false ID implied a whole infrastructure that up until now had been hidden. Once they knew of its existence, they could probably ferret it out. Hiroko, Desmond, Spencer who was deep in the system in Kasei Vallis, all exposed . . . Nirgal and Jackie, Peter, Ann . . . all of them. Because he had not been clever enough to avoid a stupid awful woman like Phyllis.

He looked around the men’s room. It was the size of two toilet stalls, one stall with a toilet, the other with a sink, a mirror, and the usual wall of dispensers: sterility pills, recreational gases. He stared at these, catching his breath and thinking things over. As plans tumbled in his mind he whispered instructions to the AI in his wristpad. Desmond had given him some very destructive viral programs, and he plugged his wristpad into Phyllis’s, and waited for the transfers to take place. With luck he could crash her entire system: personal security measures were nothing against Desmond’s military-based viruses, or so Desmond claimed.

But there was still Phyllis. The recreational gases in the wall dispenser were mostly nitrous oxide, in individual inhalers containing about two or three cubic meters of gas. The room was, he judged, about thirty-five or forty cubic meters. The ventilation grill was next to the ceiling, and could be blocked with a strip of the towel, on its roll by the sink.
