 "And if there was salt in it, sir, it wasn't me. I never took the salt near it."

"What makes you think there was salt in it?" asked Poirot.

"Seeing it on the tray, sir."

"You saw some salt on the tray?"

"Yes. Coarse kitchen salt, it looked.  I never noticed it when I took the tray up, but when I came to take it into the mistress's room I saw it at once, and I suppose I ought to have taken it down again, and asked Cook to make some fresh.  But I was in a hurry, because Dorcas was out, and I thought maybe the coco itself was all right, and the salt had only gone on the tray.  So I dusted it off with my apron, and took it in."

I had the utmost difficulty in controlling my excitement. Unknown to herself, Annie had provided us with an important piece of evidence. How she would have gaped if she had realized that her "coarse kitchen salt" was strychnine, one of the most deadly poisons known to mankind. I marvelled at Poirot's calm. His self-control was astonishing. I awaited his next question with impatience, but it disappointed me.

"When you went into Mrs. Inglethorp's room, was the door leading into Miss Cynthia's room bolted?"

"Oh! Yes, sir; it always was. It had never been opened."
