He went back and slammed his door, and I made his coffee.  I steeped a cup of tea for Mrs. Ladley at the same time.  He opened the door just wide enough for the tray, and took it without so much as a “thank you.”  He had a cigarette in his mouth as usual, and I could see a fire in the grate and smell something like scorching cloth.

“I hope Mrs. Ladley is better,” I said, getting my foot in the crack of the door, so he could not quite close it.  It smelled to me as if he had accidentally set fire to something with his cigarette, and I tried to see into the room.

“What about Mrs. Ladley?” he snapped.

“You said she was ill last night.”

“Oh, yes!  Well, she wasn’t very sick.  She’s better.”

“Shall I bring her some tea?”

“Take your foot away!” he ordered.  “No.  She doesn’t want tea.  She’s not here.”

“Not here!”

“Good heavens!” he snarled.  “Is her going away anything to make such a fuss about?  The Lord knows I’d be glad to get out of this infernal pig-wallow myself.”

“If you mean my house—­” I began.

But he had pulled himself together and was more polite when he answered.  “I mean the neighborhood.  Your house is all that could be desired for the money.  If we do not have linen sheets and double cream, we are paying muslin and milk prices.”

Either my nose was growing accustomed to the odor, or it was dying away:  I took my foot away from the door.  “When did Mrs. Ladley leave?” I asked.

“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.
