“Poirot," I said. "I have been thinking.""An admirable exercise my friend. Continue it.”

“What are you doing, Poirot?""I dissect rucksacks. It is very interesting.”

“Life can be very terrible," he said. "One needs much courage.""To kill oneself? yes, I suppose one does.""Also to live," said Poirot, "one needs courage.”
