“I thought you were just saying it for the sake of saying something,” I confessed.
“Ah, quelle idée! Later you observed me measuring the overcoat of M. Jack Renauld. Eh bien, M. Jack Renauld wears his overcoat very short. Put those two facts together with a third, namely that M. Jack Renauld flung out of the house in a hurry on his departure for Paris, and tell me what you make of it!”
“I see,” I said slowly, as the meaning of Poirot’s remarks bore in upon me. “That letter was written to Jack Renauld—not to his father. He caught up the wrong overcoat in his haste and agitation.”
Poirot nodded.
“Précisement! We can return to this point later. For the moment let us content ourselves with accepting the letter as having nothing to do with M. Renauld père, and pass to the next chronological event.”
“May 23rd,” I read, “M. Renauld quarrels with his son over latter’s wish to marry Marthe Daubreuil. Son leaves for Paris. I don’t see anything much to remark upon there, and the altering of the will the following day seems straightforward enough. It was the direct result of the quarrel.”
“We agree, mon ami—at least as to the cause. But what exact motive underlay this procedure of M. Renauld’s?”
I opened my eyes in surprise.
“Anger against his son of course.”
“Yet he wrote him affectionate letters to Paris?”
