Agatha Christie: The Mysterious Affair at Styles

CHAPTER 13. POIROT EXPLAINS (continued)

"Well, my friend, I saw there was just one chance. I was not sure then if Inglethorp was the criminal or not, but if he was I reasoned that he would not have the paper on him, but would have hidden it somewhere, and by enlisting the sympathy of the household I could effectually prevent his destroying it. He was already under suspicion, and by making 190> the matter public I secured the services of about ten amateur detectives, who would be watching him unceasingly, and being himself aware of their watchfulness he would not dare seek further to destroy the document. He was therefore forced to depart from the house, leaving it in the spill vase."

"But surely Miss Howard had ample opportunities of aiding him."

"Yes, but Miss Howard did not know of the paper's existence. In accordance with their prearranged plan, she never spoke to Alfred Inglethorp. They were supposed to be deadly enemies, and until John Cavendish was safely convicted they neither of them dared risk a meeting. Of course I had a watch kept on Mr. Inglethorp, hoping that sooner or later he would lead me to the hiding-place. But he was too clever to take any chances. The paper was safe where it was; since no one had thought of looking there in the first week, it was not likely they would do so afterwards. But for your lucky remark, we might never have been able to bring him to justice."

"I understand that now; but when did you first begin to suspect Miss Howard?"

"When I discovered that she had told a lie at the inquest about the letter she had received from Mrs. Inglethorp."

"Why, what was there to lie about?"

"You saw that letter? Do you recall its general appearance?"

"Yes--more or less."

"You will recollect, then, that Mrs. Inglethorp wrote a very distinctive hand, and left large clear spaces between her words. But if you look at the date at the top of the letter you will notice that 'July 17th' is quite different in this respect. Do you see what I mean?"
