“I thought—I thought it was the master—it looked like ’im.”

I saw Mrs. Maltravers give a terrified start, and my mind flew to the old superstition that a suicide cannot rest. She thought of it too, I am sure, for a minute later, she caught Poirot’s arm with a scream.

“Didn’t you hear that? Those three taps on the window? That’s how he always used to tap when he passed round the house.”

“The ivy,” I cried. “It was the ivy against the pane.”

But a sort of terror was gaining on us all. The parlourmaid was obviously unstrung, and when the meal was over Mrs. Maltravers besought Poirot not to go at once. She was clearly terrified to be left alone. We sat in the little morning-room. The wind was getting up, and moaning round the house in an eerie fashion. Twice the door of the room came unlatched and the door slowly opened, and each time she clung to me with a terrified gasp.

“Ah, but this door, it is bewitched!” cried Poirot angrily at last. He got up and shut it once more, then turned the key in the lock. “I shall lock it, so!”

“Don’t do that,” she gasped, “if it should come open now——”

And even as she spoke the impossible happened. The locked door slowly swung open. I could not see into the passage from where I sat, but she and Poirot were facing it. She gave one long shriek as she turned to him.

“You saw him—there in the passage?” she cried.

He was staring down at her with a puzzled face, then shook his head.
