"Since the Germans didn't, I'm inclined to," admitted Kane. "We know that more things are possible than German imagination can swallow; we've got several such things here. Of course, it's always just possible that you're German spies, using a crazy wheels-within-wheels stunt to get on the inside. I don't think so, though, and fortunately I don't have to guess." He turned to Vzryvov. "Got the apparatus set up?" "Since an hour ago," said the Russian. Kane slid off the table top. He became brusque. "If you'll just step into the next room, we'll read your minds and settle all doubts." * * * * * Fifteen minutes later, Igor Vzryvov switched off the psychoanalyzer. Manning glanced up under the spidery hemisphere of wire that gathered the faint broadcasts of the brain, and met Kane's warm smile. The underground leader tossed aside the graphs he had been studying, and extended a welcoming hand. "You're genuine, all right. No need to examine your friend--your mind says he came with you out of the past, and that's enough and to spare." "Swell!" said Dugan. "I didn't much like the idea of having that thing poking around inside my head." Kane caressed the machine affectionately. "This is one of the best achievements of cellar science. Thanks to it, we've got the only leak-proof organization this sinful world has ever seen. The Nazi party is one of the tightest setups ever created without benefit of the psychoanalyzer, and we've got men inside it--but we _know_ that all our members are loyal and stable." His expression darkened. "Of course, if this and our other psychoelectronic developments got into German hands, we'd be sunk. With their resources, they could exploit the field a lot more thoroughly than we can. For example, Igor here has invented a death ray that kills by just convincing a man he's dead--but to make it an effective weapon would take a lot more power. We get a good deal of leakage here from the Long Island station, but we have to be careful about antennas." The four of them sat around the table in the outer room. Harry Clark had disappeared--literally, and then gone out to pass the word to the agents scattered around New York that the men they sought had been found. "Now," said Kane, "since you're really time travelers, I'm on fire to hear how you did it. A time machine might be a useful addition to our arsenal, though it sounds like a tricky thing to use...." "I'm afraid we can't help on that score," said Manning, and related the whole story of their experience with Herr Doktor Kahl's _Zeitfahrer_. Kane rubbed his chin thoughtfully. "So you're stranded in our time. I feel for you! At least the Germans didn't get the machine, either--though they have got the inventor. We may have to do something about that. And what about you? Have any plans?"
