"Poirot," I said, "your gaiety does not deceive me. This is a very important discovery."
"I do not know," said Poirot. "But one thing does strike me. No doubt it has struck you too."
"What is that?"
"Why, that there is altogether too much strychnine about this case. This is the third time we run up against it. There was strychnine in Mrs. Inglethorp's tonic. There is the strychnine sold across the counter at Styles St. Mary by Mace. Now we have more strychnine, handled by one of the household. It is confusing; and, as you know, I do not like confusion."Before I could reply, one of the other Belgians opened the door and stuck his head in.
