There was no mistaking the sincerity of this. It was a poignant outcry. Clearly, she was at the breaking-point. He took both her hands.

"This whole experience gives me the oddest feeling," he told her gently. "In one way, I seem to be dreaming it. Under it all there's a conviction that I'm on the track of the mystery; that everything will be cleared up, for us both, in another minute or two. It's merely an instinct. I can't explain it. But one thing I know. Sooner or later—sooner, I hope—I shall be able to work it out for you."

She seemed suddenly to remember that he was holding her hands. Flushing, she gently withdrew them. Then she turned, and with a brusque gesture walked away from him.

"I'm sorry I got you into this!" she cried.

"Don't worry about me." He smiled at her from the door he was holding open. "May I come and take you to lunch to-morrow?"

"Not to-morrow. The next day, perhaps."

"We've got to look for that job, you know."

"With all this?" She indicated with the toe of her slipper a significant spot on the rug.

Laurie regarded the slipper with approval. It was a beautiful slipper, on a charming foot. It so diverted his mind from the main issue of the conversation that he was in the elevator and half-way down to the ground floor before he recalled that issue. He was not disturbed. Doris had enough to go on with; and certainly he himself had sufficient scope for thought in the revelations she had just made.

As he walked down the outer steps of the studio building and emerged on the sidewalk, a figure detached itself from the shadow of a low iron fence and stealthily followed him. It was a short figure, overcoated out of recognition. It carried its hands in its pockets, and its head was thrust forward in a peculiar way. It kept a dozen feet behind him, until he reached the pretentious entrance of the apartment building where he dwelt.
