He had abandoned his private practice almost entirely, and I know that at this time he refused some remarkably handsome fees. True, he would sometimes investigate cases which intrigued him, but he usually dropped them the moment he was convinced that they had no connection with the activities of the Big Four.
This attitude of his was remarkably profitable to our friend, Inspector Japp. Undeniably he gained much kudos for solving several problems in which his success was really due to a half-contemptuous hint from Poirot.
In return for such service Japp supplied full details of any case which he thought might interest the little Belgian, and when he was put in charge of what the newspaper called "The Yellow Jasmine Mystery," he wired Poirot, asking him whether he would care to come down and look into the case.
It was in response to this wire that, about a month after my adventure in Abe Ryland's house, we found ourselves alone in a railway compartment whirling away from the smoke and dust of London, bound for the little town of Market Handford in Worcestershire, the seat of the mystery.
Poirot leant back in his corner.
"And what exactly is your opinion of the affair, Hastings?"
I did not at once reply to his question; I felt the need of going warily.
"It all seems so complicated," I said cautiously.
"Does it not?" said Poirot delightedly.
"I suppose our rushing off like this is a pretty clear sign that you consider Mr. Paynter's death to be murder—not suicide or the result of an accident?"
