Penny had noted that the key was taken from a mailbox which bore the number, 381.

“So my friend, the gardener, has an alias,” she mused. “Several of them, perhaps.”

Another half hour elapsed while the girl waited patiently in her chair. Each time the elevator descended she watched the people alight. At exactly six forty-five Mr. Hammil stepped out of the lift, and without glancing toward the girl, dropped his key on the desk and went into the dining room.

The clerk, busy with several newcomers at the hotel, did not notice. Thinking that she saw her chance, Penny slipped from her chair, sidled toward the desk and picked up the key. Her heart pounded as she walked toward the elevator, but no one called to her. Her action had passed unobserved.

“Third floor,” said Penny, and the elevator shot upward.

She located room 381 at the far end of the hall, and with a quick glance in both directions, unlocked the door and entered.

An open suitcase lay upon the luggage rack by the dresser. In systematic fashion Penny went through it, finding an assortment of interesting articles—a revolver, and two wigs, one of gray hair, the other black. There were no letters or papers, nothing to positively identify the owner of the luggage. But in the very bottom of the case Penny came upon a photograph. It was a picture of Sylvia Kippenberg.

Penny slipped the picture into the front of her dress, hastily replaced everything as she had found it, relocked the door, and returned to the lobby. As she went toward the desk intending to rid herself of the key, she stopped short.

Jerry Livingston stood there talking earnestly with the clerk.

“But I was told to come here,” she heard him protest.
