Perhaps five minutes passed. Then Cecilie and Dr. Preston suddenly emerged from the reception room. Evidently the maid was anxious to get away, perhaps afraid to be seen with him. With a word, she almost ran down the corridor in the direction of the rear elevators, and Preston, with a queer look on his face, came slowly toward me.

Instinctively I drew back into a telephone booth; then it occurred to me that if I emerged just as he passed he would not be likely to suspect anything, and I might have a chance to study him.

I did so, and was quite amused at the look of surprise on his face as I greeted him. Still, I do not think he thought I was shadowing him. We paused for a moment on the street, after a conventional exchange of remarks about the tragedy to poor little Rawaruska.

"That Miss Hoffman seems to be a very capable woman," I remarked, by way of dragging the conversation into channels into which it seemed unlikely to drift naturally.

"Y-yes," he agreed, as I caught a sidelong glance from the corner of his eye. "I believe she has had a rather checkered career. I understand that she was a nurse, a trained nurse, once."

There was something about the remark that impressed me. It was made deliberately, I fancied. What his purpose was, I could not fathom, but I felt that in the instant while he had hesitated he had debated and made up his mind to say it.

My face betraying nothing to his searching glance, he pulled hastily at his watch. "I'm going downtown on the subway—to clear up some of the muss that this European business has got me in with my bankers," he said quickly. "I'd be glad to have you call on me at any time at the Charlton, just up the avenue a bit. Good-day, sir. I'm glad to have met you. Drop in on me."

He was gone, scarcely waiting for me to reply, leaving me to wonder what was the cause of his strange actions.

Mechanically I looked at my own watch and decided that I had left Craig undisturbed long enough.
