“Done?” he drawled. “Why, as soon as mother told me of the letter, I left an envelope up at the Prince Henry, as it directed.”

“With the money?” put in Craig quickly.

“Oh, no—just as a decoy.”

“Yes. What happened?”

“Well, I waited around a long time. It was far along in the day when a woman appeared at the desk. I had instructed the clerk to be on the watch for anyone who asked for mail addressed to a Dr. Hopf. The clerk slammed the register. That was the signal. I moved up closer.”

“What did she look like?” asked Kennedy keenly.

“I couldn’t see her face. But she was beautifully dressed, with a long light flowing linen duster, a veil that hid her features and on her hands and arms a long pair of motoring doeskin gloves. By George, she was a winner—in general looks, though. Well, something about the clerk, I suppose, must have aroused her suspicions. For, a moment later, she was gone in the crowd. Evidently she had thought of the danger and had picked out a time when the lobby would be full and everybody busy. But she did not leave by the front entrance through which she entered. I concluded that she must have left by one of the side street carriage doors.”

“And she got away?”

“Yes. I found that she asked one of the boys at the door to crank up a car standing at the curb. She slid into the seat, and was off in a minute.”

Kennedy said nothing. But I knew that he was making a mighty effort to restrain comment on the bungling amateur detective work of the son of our client.
