ABC Murders - Agatha Christie [76]
Poirot interrupted.
“You are quite wrong. He admits the fact.”
“What?” Clarke looked really startled.
“Oh, yes,” said Poirot gently. “I had no sooner spoken to him than I was aware that Cust believed himself to be guilty.”
“And even that didn’t satisfy M. Poirot?” said Clarke.
“No. Because as soon as I saw him I also knew that he could not be guilty! He has neither the nerve nor the daring—nor, I may add, the brains to plan! All along I have been aware of the dual personality of the murderer. Now I see wherein it consisted. Two people were involved—the real murderer, cunning, resourceful and daring—and the pseudo murderer, stupid, vacillating and suggestible.
“Suggestible—it is in that word that the mystery of Mr. Cust consists! It was not enough for you, Mr. Clarke, to devise this plan of a series to distract attention from a single crime. You had also to have a stalking horse.
“I think the idea first originated in your mind as the result of a chance encounter in a city coffee den with this odd personality with his bombastic Christian names. You were at that time turning over in your mind various plans for the murder of your brother.”
“Really? And why?”
“Because you were seriously alarmed for the future. I do not know whether you realize it, Mr. Clarke, but you played into my hands when you showed me a certain letter written to you by your brother. In it he displayed very clearly his affection and absorption in Miss Thora Grey. His regard may have been a paternal one—or he may have preferred to think it so. Nevertheless, there was a very real danger that on the death of your sister-in-law he might, in his loneliness, turn to this beautiful girl for sympathy and comfort and it might end—as so often happens with elderly men—in his marrying her. Your fear was increased by your knowledge of Miss Grey. You are, I fancy, an excellent, if somewhat cynical judge of character. You judged, whether correctly or not, that Miss Grey was a type of young woman ‘on the make.’ You had no doubt that she would jump at the chance of becoming Lady Clarke. Your brother was an extremely healthy and vigorous man. There might be children and your chance of inheriting your brother’s wealth would vanish.
“You have been, I fancy, in essence a disappointed man all your life. You have been the rolling stone—and you have gathered very little moss. You were bitterly jealous of your brother’s wealth.
“I repeat then that, turning over various schemes in your mind, your meeting with Mr. Cust gave you an idea. His bombastic Christian names, his account of his epileptic seizures and of his headaches, his whole shrinking and insignificant personality, struck you as fitting him for the tool you wanted. The whole alphabetical plan sprang into your mind—Cust’s initials—the fact that your brother’s name began with a C and that he lived at Churston were the nucleus of the scheme. You even went so far as to hint to Cust at his possible end—though you could hardly hope that that suggestion would bear the rich fruit that it did!
“Your arrangements were excellent. In Cust’s name you wrote for a large consignment of hosiery to be sent to him. You yourself sent a number of A B C’s looking like a similar parcel. You wrote to him—a typed letter purporting to be from the same firm offering him a good salary and commission. Your plans were so well laid beforehand that you typed all the letters that were sent subsequently, and then presented him with the machine on which they had been typed.
“You had now to look about for two victims whose names began with A and B respectively and who lived at places also beginning with those same letters.
“You hit on Andover as quite a likely spot and your preliminary reconnaissance there led you to select Mrs. Ascher’s shop as the scene of the first crime. Her name was written clearly over the door, and you found by experiment that she was usually alone in the shop. Her murder needed nerve, daring and reasonable luck.
“For the letter B you had to vary your tactics. Lonely women in shops might conceivably
