He smiled. “Bien. From my good friend Catchpool, I shall endeavor to learn the comportement straightforward. I start immediately!” He produced an envelope from his pocket. “This arrived for me an hour ago. You might not welcome my interference in your personal affairs, Catchpool—you may think, ‘Poirot, he sticks in his oar where it is not wanted’—but this letter expresses gratitude for that very vice of mine that you find so intolerable.”

“If you’re referring to Fee Spring, she is not my ‘personal affairs’ and never will be,” I said, eyeing the missive in his hand. “Which poor stick’s private business have you meddled in now? And gratitude for what?”

“For bringing together two people who love each other very much.”

“Who is the letter from?”

Poirot smiled. “Dr. and Mrs. Ambrose Flowerday,” he said. And he handed it to me to read.
