The ABC Murders by Agatha Christie

being in any way associated with a failure, when on July 25th it was suddenly revived.
    I had not seen Poirot for a couple of days as I had been away in Yorkshire for the weekend. I arrived back on Monday afternoon and the letter came by the six o’clock post. I remember the sudden, sharp intake of breath that Poirot gave as he slit open that particular envelope.
    â€œIt has come,” he said.
    I stared at him—not understanding.
    â€œWhat has come?”
    â€œThe second chapter of the A B C business.”
    For a minute I looked at him uncomprehendingly. The matter had really passed from my memory.
    â€œRead,” said Poirot and passed me over the letter.
    As before, it was printed on good-quality paper.
    Dear Mr. Poirot,—Well, what about it? First game to me, I think. The Andover business went with a swing, didn’t it?
    But the fun’s only just beginning. Let me draw your attention to Bexhill-on-Sea. Date, the 25th inst.
    What a merry time we are having! Yours etc.
    A B C
    â€œGood God, Poirot,” I cried. “Does this mean that this fiend is going to attempt another crime?”
    â€œNaturally, Hastings. What else did you expect? Did you think that the Andover business was an isolated case? Do you not remember my saying: ‘This is the beginning’?”
    â€œBut this is horrible!”
    â€œYes, it is horrible.”
    â€œWe’re up against a homicidal maniac.”
    â€œYes.”
    His quietness was more impressive than any heroics could have been. I handed back the letter with a shudder.
    The following morning saw us at a conference of powers. The Chief Constable of Sussex, the Assistant Commissioner of the CID, Inspector Glen from Andover, Superintendent Carter of the Sussex police, Japp and a younger inspector called Crome, and Dr. Thompson, the famous alienist, were all assembled together. The postmark on this letter was Hampstead, but in Poirot’s opinion little importance could be attached to this fact.
    The matter was discussed fully. Dr. Thompson was a pleasant middle-aged man who, in spite of his learning, contented himself with homely language, avoiding the technicalities of his profession.
    â€œThere’s no doubt,” said the Assistant Commissioner, “that the two letters are in the same hand. Both were written by the same person.”
    â€œAnd we can fairly assume that that person was responsible for the Andover murder.”
    â€œQuite. We’ve now got definite warning of a second crime scheduled to take place on the 25th—the day after tomorrow—at Bexhill. What steps can be taken?”
    The Sussex Chief Constable looked at his superintendent.
    â€œWell, Carter, what about it?”
    The superintendent shook his head gravely.
    â€œIt’s difficult, sir. There’s not the least clue towards whom the victim may be. Speaking fair and square, what steps can we take?”
    â€œA suggestion,” murmured Poirot.
    Their faces turned to him.
    â€œI think it possible that the surname of the intended victim will begin with the letter B.”
    â€œThat would be something,” said the superintendent doubtfully.
    â€œAn alphabetical complex,” said Dr. Thompson thoughtfully.
    â€œI suggest it as a possibility—no more. It came into my mind when I saw the name Ascher clearly written over the shop door of the unfortunate woman who was murdered last month. When I got the letter naming Bexhill it occurred to me as a possibility that the victim as well as the place might be selected by an alphabetical system.”
    â€œIt’s possible,” said the doctor. “On the other hand, it may be that the name Ascher was a coincidence—that the victim this time, no matter what her name is, will again be an old woman who keeps a shop. We’re dealing, remember, with a madman. So far he hasn’t given us any clue as to motive.”
    â€œHas a madman any motive, sir?” asked the
