“Think, my friend,” said Poirot’s voice encouragingly. “Arrange your ideas. Be methodical. Be orderly. There is the secret of success.”

I endeavoured to obey him, casting my mind back over all the details of the case. And reluctantly it seemed to me that the only clear and possible solution was that of Giraud—which Poirot despised. I reflected anew. If there was daylight anywhere it was in the direction of Madame Daubreuil. Giraud was ignorant of her connection with the Beroldy Case. Poirot had declared the Beroldy Case to be all important. It was there I must seek. I was on the right track now. And suddenly I started as an idea of bewildering luminosity shot into my brain. Trembling I built up my hypothesis.

“You have a little idea, I see, mon ami! Capital. We progress.”

I sat up, and lit a pipe.

“Poirot,” I said, “it seems to me we have been strangely remiss. I say we—although I dare say I would be nearer the mark. But you must pay the penalty of your determined secrecy. So I say again we have been strangely remiss. There is some one we have forgotten.”

“And who is that?” inquired Poirot, with twinkling eyes.

“Georges Conneau!”

An Amazing Statement
