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?"

Manning met his eyes squarely. "A hundred years ago, we were fighting a war. It seems we lost it—how or why, I don't know. I don't think we lost it in the fighting, but probably before it ever began, when we were complacent and let the Germans get a head start in preparation and invention. Anyway, for us that's still unfinished business."

"And we'd like the chance to finish it!" stated Dugan bluntly.

Kane smiled with a touch of sadness. Vzryvov said explosively, "The end may be soon!" and his eyes burned.

In Manning's memory flashed the vision of a mocking face. He asked abruptly: "What did Schwinzog mean: 'A message for America—one week to live'?"

The shadow on Kane's face deepened, but he did not show surprise. "I guess he meant just that. That the Germans are about ready to do to America what they did to Russia fifty years ago.... But of course you don't know anything about the history of the last century. If you want to catch up on the missing chapters, I've got a fair-sized collection of books on the subject. All the ones dealing with events since the War of the Conquest are German, of course—English has just about stopped being a written language—and you'll probably find they don't even agree on what you know. You said, didn't you, that you were with an American army advancing into Germany?"
