"Turn me loose; then ask me in a nice way. As far as I know, I haven't got anything of military significance to tell you, but if I were treated as a free citizen I might be inclined to let you be the judge of that." "Tell us now; then you'll go free." "Sure," I said. "I invented a combination rocket ship and time machine. I travelled around the solar system and made a few short trips back into history. In my spare time I invented other gadgets. I'm planning to take out patents, so naturally I don't intend to spill any secrets. Can I go now?" Smale got to his feet. "Until we can safely move you, you'll remain in this room. You're on the sixty-third floor of the Yordano Building. The windows are of unbreakable glass, in case you contemplate a particularly untidy suicide. Your person has been stripped of all potentially dangerous items. The door is of heavy construction and securely locked. The furniture has been removed so you can't dismantle it for use as a weapon. It's rather a drab room to spend your future in, but until you decide to co-operate this will be your world." * * * * * I didn't say anything. I sat on the floor and watched him leave. I caught a glimpse of two uniformed men outside the door. No doubt they'd take turns looking through the peephole. I'd have solitude without privacy. I stretched out on the floor, which was padded with a nice thick rug, presumably so that I wouldn't beat my brains out against it just to spite them. I was way behind on my sleep: being interrogated while unconscious wasn't a very restful procedure. I wasn't too worried. In spite of what Smale said, they couldn't keep me here forever. Maybe Margareta had gotten clear and told the story to some newsmen; this kind of thing couldn't stay hidden forever. Or could it? I thought about what Smale had said about my talking gibberish under the narcotics. That was an odd one.... Quite suddenly I got it. By means of the drugs they must have tapped a level where the Vallonian background briefing was stored: they'd been firing questions at a set of memories that didn't speak English. I grinned, then laughed out loud. Luck was still in the saddle with me. * * * * * The glass was in double panels, set in aluminum frames and sealed with a plastic strip. The space between the two panels of glass was evacuated of air, creating an insulating barrier against the heat of the sun. I ran a finger over the aluminum. It was dural: good tough stuff. If I had something to pry with, I might possibly lever the metal away from the glass far enough to take a crack at the edge, the weak point of armor-glass ... if I had something to hit it with.
