"This morning, very early. I rowed her to Federal Street."

"You couldn't have had much sleep," I said dryly. For he looked horrible. There were lines around his eyes, which were red, and his lips looked dry and cracked.

"She's not in the piece this week at the theater," he said, licking his lips and looking past me, not at me. "She'll be back by Saturday."

I did not believe him. I do not think he imagined that I did. He shut the door in my face, and it caught poor Peter by the nose. The dog ran off howling, but although Mr. Ladley had been as fond of the animal as it was in his nature to be fond of anything, he paid no attention. As I started down the hall after him, I saw what Peter had been carrying—a slipper of Mrs. Ladley's. It was soaked with water; evidently Peter had found it floating at the foot of the stairs.

Although the idea of murder had not entered my head at that time, the slipper gave me a turn. I picked it up and looked at it—a black one with a beaded toe, short in the vamp and high-heeled, the sort most actresses wear. Then I went back and knocked at the door of the front room again.

"What the devil do you want now?" he called from beyond the door.

"Here's a slipper of Mrs. Ladley's," I said. "Peter found it floating in the lower hall."

He opened the door wide, and let me in. The room was in tolerable order, much better than when Mrs. Ladley was about. He looked at the slipper, but he did not touch it. "I don't think that is hers," he said.

"I've seen her wear it a hundred times."

"Well, she'll never wear it again." And then, seeing me stare, he added: "It's ruined with the water. Throw it out. And, by the way, I'm sorry, but I set fire to one of the pillow-slips—dropped asleep, and my cigarette did the rest. Just put it on the bill."
