for a sign. Within ten minutes after their entry, three men had come in and sat down, two of them together. They might have been ordinary customers, but to Manning's covertly searching gaze they did not look sufficiently undernourished to be twenty-first century Americans. They looked like Germans. The next arrivals were a youthful couple, and then for a while no one came in. Manning ordered another cup of "coffee." Then he got a shock. For when he looked down, reaching for his cup, it was gone. He blinked, and it was there, solid, chipped and stained. He glanced briefly up at the unnoticing Dugan, then back to the cup—and there was no cup. And then there was, and he sat and squinted at it, struggling with a glimmer of understanding that this was what he had been waiting for. Their table was for four.

Further instructions then. Act natural!" Despite the final injunction, Manning hardly knew how they got out onto the street. Out of possible earshot of their shadows, he explained hurriedly to Dugan. "I thought they'd try to contact us. We have the Gestapo itself to thank for that, I'll bet. Even if it can't put the finger on the underground, it must know enough about them so that we were dumped off here for bait, it could let the word go out so that the underground would hear about us and grab at the bait right away.
