“But the tramp. Where does he come in?”
Poirot shrugged his shoulders.
“Giraud would say that he was an accomplice—an apache who helped young Renauld to commit the crime, and who was conveniently put out of the way afterwards.”
“But the hair round the dagger? The woman’s hair?”
“Ah,” said Poirot, smiling broadly. “That is the cream of Giraud’s little jest. According to him, it is not a woman’s hair at all. Remember that the youths of today wear their hair brushed straight back from the forehead with pomade or hairwash to make it lie flat. Consequently some of the hairs are of considerable length.”
“And you believe that too?”
“No,” said Poirot with a curious smile. “For I know it to be the hair of a woman—and more, which woman!”
“Madame Daubreuil,” I announced positively.
“Perhaps,” said Poirot, regarding me quizzically.
But I refused to allow myself to get annoyed.
