It was growing cold, as the afternoon settled down. It had not been as warm a day to begin with, he suspected, as it had been in his Berlin. He wondered how it might be, that Germany's losing a war could change the weather, but the important thing was that he was shivering. He was beginning to attract attention not only for his suit but for his lack of a coat.

He had now no place to go, no place to stay the night, no way of getting food. He had no papers, and no knowledge of where to get them or what sort of maneuver would be required to keep him safe from arrest. If anything could save him from arrest. By Russians.

Professor Kempfer began to walk with dragging steps, his body sagging and numb. More and more of the passersby were looking at him sharply. They might well have an instinct for a hunted man. He did not dare look at the occasional policeman.

He was an old man. He had run today, and shaken with nervous anticipation, and finished fifteen years' work, and it had all been a nightmarish error. He felt his heart begin to beat unnaturally in his ears, and he felt a leaping flutter begin in his chest. He stopped, and swayed, and then he forced himself to cross the sidewalk so he could lean against a building. He braced his back and bent his knees a little, and let his hands dangle at his sides.

The thought came to him that there was an escape for him into one more world. His shoulder-blades scraped a few centimeters downward against the wall.

There were people watching him. They ringed him in at a distance of about two meters, looking at him with almost childish curiosity. But there was something about them that made Professor Kempfer wonder at the conditions that could produce such children. As he looked back at them, he thought that perhaps they all wanted to help him—that would account for their not going on about their business. But they did not know what sort of complications their help might bring to them—except that there would certainly be complications. So none of them approached him. They gathered around him, watching, in a crowd that would momentarily attract a volkspolizier.

He looked at them dumbly, breathing as well as he could, his palms flat against the wall. There were stocky old women, round-shouldered men, younger men with pinched faces, and young girls with an incalculable wisdom in their eyes. And there was a bird-like older woman, coming quickly along the sidewalk, glancing at him curiously, then hurrying by, skirting around the crowd....

There was one possibility of his escape to this world that Professor Kempfer had not allowed himself to consider. He pushed himself away from the wall, scattering the crowd as though by physical force, and lurched toward the passing woman.

"Marthe!"
