In spite of myself, my opinion of his sagacity was immeasurably heightened. I would never have dreamt of suspecting the doctor, had not Poirot put it into my head. Yes, decidedly, the little man was clever.

After some reflecting, I decided to take John into my confidence, and leave him to make the matter public or not, as he thought fit.

He gave vent to a prodigious whistle, as I imparted the news.

"Great Scot! You _were_ right, then. I couldn't believe it at the time."

"No, it is astonishing until you get used to the idea, and see how it makes everything fit in. Now, what are we to do? Of course, it will be generally known to-morrow."

John reflected.

"Never mind," he said at last, "we won't say anything at present. There is no need. As you say, it will be known soon enough."

But to my intense surprise, on getting down early the next morning, and eagerly opening the newspapers, there was not a word about the arrest! There was a column of mere padding about "The Styles Poisoning Case," but nothing further. It was rather inexplicable, but I supposed that, for some reason or other, Japp wished to keep it out of the papers. It worried me just a little, for it suggested the possibility that there might be further arrests to come.
