the dark figure in the doorway. They would never help me anyway, Harry thought bitterly. He had tried that before, and met with ridicule and threats. There would be no help from the police in the Old City. Another figure came around a corner. There was something vaguely familiar about the tall body and broad shoulders as the man walked across the wet street, something Harry faintly recognized from somewhere during the spinning madness of the past few weeks. The man's eyes turned up toward the window for the briefest instant, then returned steadfastly to the street. Oh, they were sly! You could never spot them looking at you, never for sure, but they were always there, always nearby. And there was no one he could trust any longer, no one to whom he could turn. Not even George Webber. Swiftly his mind reconsidered that possibility as he watched the figure move down the street. True, Dr. Webber had started him out on this search in the first place.

He could just wait, and run, and wait— It was almost dark now and the creaking of the old board house intensified the fear that tore at Harry Scott's mind. Tonight was the night; he was sure of it. Maybe he had been foolish in coming here to the slum area, where the buildings were relatively unguarded, where anybody could come and go as he
