"Mon ami, for the moment it is an open question. I would just point out to you that Claud Darrell has been in China and America—a fact not without significance, perhaps, but we must not allow ourselves to be unduly biased by that point. It may be a mere coincidence."

"And the next step?" I asked eagerly.

"Affairs are already in train. Every day cautiously worded advertisements will appear. Friends and relatives of one or the other will be asked to communicate with my solicitor at his office. Even to-day we might—Aha, the telephone! Probably it is, as usual, the wrong number, and they will regret to have troubled us, but it may be—yes, it may be—that something has arisen."

I crossed the room and picked up the receiver.

"Yes, yes. M. Poirot's rooms. Yes, Captain Hastings speaking. Oh, it's you, Mr. McNeil! (McNeil and Hodgson were Poirot's solicitors.) I'll tell him. Yes, we'll come round at once."

I replaced the receiver and turned to Poirot, my eyes dancing with excitement.

"I say, Poirot, there's a woman there. Friend of Claud Darrell's. Miss Flossie Monro. McNeil wants you to come round."

"At the instant!" cried Poirot, disappearing into his bedroom, and reappearing with a hat.

A taxi soon took us to our destination, and we were ushered into Mr. McNeil's private office. Sitting in the arm-chair facing the solicitor was a somewhat lurid looking lady no longer in her first youth. Her hair was of an impossible yellow, and was prolific in curls over each ear, her eyelids were heavily blackened, and she had by no means forgotten the rouge and the lip salve.

"Ah, here is M. Poirot!" said Mr. McNeil. "M. Poirot, this is Miss—er—-Monro, who has very kindly called to give us some information."
