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!"

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.

"I saw him—my husband—you must have seen him too?"
"Madame, I saw nothing. You are not well—unstrung———"
"I am perfectly well, I———Oh, God!"
