certainly worked miracles. As far as he could judge, he was completely normal. The medic was surprised to find him sitting up when she made her morning rounds. It was amazing, but this case was amazing in more ways than one. Last night he had been in a state of complete collapse, and now he was well on the road to recovery. Albert looked at her curiously. "What was in that stuff you gave me?" "Just dextrose and saline," she said. "I couldn't find anything wrong with you except hypoglycemia and dehydration, so I treated that." She paused and eyed him with a curiosity equal to his own. "Just what do you think happened?" she asked. "I think I was poisoned." "That's impossible." "Possibly," Albert conceded, "but it might be an idea to check that food I left all over the cell." "That was cleaned up hours ago." "Convenient, isn't it?" "I don't know what you mean by that," she said. "Someone in the kitchens might have made a mistake. Yet you were the only case." She looked thoughtful. "I think I will do a little checking in the Central Kitchen, just to be on the safe side." She smiled a bright professional smile. "Anyway, I'm glad to see that you have recovered so well. I'm sure you can go back tomorrow." She vanished through the door with a rustle of white dacron. Albert, after listening a moment to make sure that she was gone, rose to his feet and began an inspection of his room. It wasn't a jail cell. Not quite. But it wasn't designed for easy escape, either. It was on the top floor of the IC building, a good hundred feet down to the street below. The window was covered with a steel grating and the door was locked. But both window and door were designed to hold a sick man rather than a healthy and desperate one. Albert looked out of the window. The building was constructed to harmonize with native structures surrounding it, so the outer walls were studded with protuberances and bosses that would give adequate handholds to a man strong enough to brave the terrors of the descent.
