"I don't know, Mademoiselle," said Poirot. "See, I admit it frankly. As a rule I know everything, but in this case, I—well, I do not. You, perhaps, know better than I do."

"You believe he did it?" she said abruptly.
Poirot shrugged his shoulders.
"The police say so."
"Ah," said Lenox, "hedging, are you? So there is something to hedge about."
Again she was silent, frowning. Poirot said gently:
"You have known Derek Kettering a long time, have you not?"
