I think the appearance of the two Scotland Yard men was rather a shock⁠—especially to John, though of course after the verdict, he had realized that it was only a matter of time. Still, the presence of the detectives brought the truth home to him more than anything else could have done.

Poirot had conferred with Japp in a low tone on the way up, and it was the latter functionary who requested that the household, with the exception of the servants, should be assembled together in the drawing-room. I realized the significance of this. It was up to Poirot to make his boast good.

Personally, I was not sanguine. Poirot might have excellent reasons for his belief in Inglethorp’s innocence, but a man of the type of Summerhaye would require tangible proofs, and these I doubted if Poirot could supply.
