 “You are wrong, Hastings. He could not blackmail her, for she had the whip hand. Georges Conneau, remember, is still wanted for murder. A word from her and he is in danger of the guillotine.”

I was forced, rather reluctantly, to admit the truth of this.

“Your theory,” I remarked acidly, “is doubtless correct as to all the details?”

“My theory is the truth,” said Poirot quietly. “And the truth is necessarily correct. In your theory you made a fundamental error.

“The letter to you?”

“That was the first we knew of it, but it is not the proper
