The parlourmaid, summoned, led Poirot upstairs. I remained with the lovely and unfortunate woman. It was hard to know whether to speak or remain silent. I essayed one or two general reflections to which she responded absently, and in a very few minutes Poirot rejoined us.

“I thank you for all your courtesy, madame. I do not think you need be troubled any further with this matter. By the way, do you know anything of your husband’s financial position?”

She shook her head.

“Nothing whatever. I am very stupid over business things.”

“I see. Then you can give us no clue as to why he suddenly decided to insure his life? He had not done so previously, I understand.”

“Well, we had only been married a little over a year. But, as to why he insured his life, it was because he had absolutely made up his mind that he would not live long. He had a strong premonition of his own death. I gather that he had had one hæmorrhage already, and that he knew that another one would prove fatal. I tried to dispel these gloomy fears of his, but without avail. Alas, he was only too right!”

Tears in her eyes, she bade us a dignified farewell. Poirot made a characteristic gesture as we walked down the drive together.

Eh bien, that is that! Back to London, my friend, there appears to be no mouse in this mouse-hole. And yet——”

“Yet what?”

“A slight discrepancy, that is all! You noticed it? You did not? Still, life is full of discrepancies, and assuredly the man cannot have taken his own life—there is no poison that would fill his mouth with blood. No, no, I must resign myself to the fact that all here is clear and above-board—but who is this?”
