"IT ISN'T STRYCHNINE, IS IT?"
He laughed with apparent enjoyment, raising his arms to heaven in mock despair, in what I could not but consider the worst possible taste.
"And, anyway," I said, with increasing coldness, "as Mrs. Inglethorp took her coffee upstairs with her, I do not see what you expect to find, unless you consider it likely that we shall discover a packet of strychnine on the coffee tray!"
Poirot was sobered at once.
"Come, come, my friend," he said, slipping his arm through mine. "Ne vous fâchez pas! Allow me to interest myself in my coffee cups, and I will respect your coco. There! Is it a bargain?"
He was so quaintly humorous that I was forced to laugh; and we went together to the drawing-room, where the coffee cups and tray remained undisturbed as we had left them.
Poirot made me recapitulate the scene of the night before, listening very carefully, and verifying the position of the various cups.
"So Mrs. Cavendish stood by the tray—and poured out. Yes. Then she came across to the window where you sat with Mademoiselle Cynthia. Yes. Here are the three cups. And the cup on the mantel-piece, half drunk, that would be Mr. Lawrence Cavendish's. And the one on the tray?"
"John Cavendish's. I saw him put it down there."
