"I believe, Mr. Inglethorp, that you yourself poured out the coffee, and took it to your wife that evening?"

"I poured it out, yes. But I did not take it to her. I meant to do so, but I was told that a friend was at the hall door, so I laid down the coffee on the hall table. When I came through the hall again a few minutes later, it was gone."

This statement might, or might not, be true, but it did not seem to me to improve matters much for Inglethorp. In any case, he had had ample time to introduce the poison.

At that point, Poirot nudged me gently, indicating two men who were sitting together near the door. One was a little, sharp, dark, ferret-faced man, the other was tall and fair.

I questioned Poirot mutely. He put his lips to my ear.

"Do you know who that little man is?"

I shook my head.

"That is Detective Inspector James Japp of Scotland Yard- Jimmy Japp. The other man is from Scotland Yard too. Things are moving quickly, my friend."

I stared at the two men intently. There was certainly nothing of the policeman about them. I should never have suspected them of being official personages.

I was still staring, when I was startled and recalled by the verdict being given:

"Wilful Murder against some person or persons unknown."
