Alan smiled wryly. "I threw him out once—a snaky sort of fellow. We want none of him—do we, sister?"

"No," she said. "Tell Edward about Dr. Turber's life—father's theory."

"It wouldn't mean much to you, Ed. There were things—so father thought—of mystery about this Turber. Things inexplicable. His curious, unexplained absences from the hospital. Things about him which father sensed. And the searchlight, that for no apparent reason for years now has been occasionally flashing from the hospital roof. It marks Turber's absence, I know that much."

Had there actually been a policeman, there in the park, who had seen it? And was there existing, here in New York today, this girl of the shadows?

We waited, and the thing turned tangible indeed! Became a reality, for presently we learned that it had touched others than ourselves.

The early afternoon papers carried a small item. Some of them put it on the front page. But it was only a joke—a little thing to read, to laugh at, and forget. There had been in actuality, a policeman at dawn in Central Park; and he had been less reticent, more incautious than ourselves. He had told what he saw. And the newspapers wrote it:
