"Everything to my mind points to him as the murderer. Whether he knew all along of the existence of the compromising letters, or whether he first knew of this through the conversation between her ladyship and Clarke the day of the servants' party, it is impossible to say; certain it is that he did overhear that conversation and that he made up his mind to end the impossible situation then and there, and to put a stop once and for all to any further attempt at blackmail. "It was easy enough for him on that day to pass in and out of the house unperceived. No doubt his primary object in going to Hardacres was to purchase the letters from Miss Clarke, money down; perhaps she proved obstinate, perhaps he merely thought that dead men tell no tales. This we shall never know. "After the hideous deed, which must have revolted his otherwise fastidious senses, he must have become conscious of an overwhelming hatred for the man who had, as it were, pushed him into crime, and my belief is that the elaborate _mise en scène_ of the khaki tunic, and the circumstantial lie that when he came out of the smoking-room Arthur Clarke had obviously just come in from outside was invented, not so much with the object of averting any suspicion from himself, as with the passionate desire to be revenged on Clarke. "Think it over," the Old Man in the Corner concluded, as he stuffed his beloved bit of string into his capacious pocket; "time, opportunity, motive, all are in favour of my theory, so do not be surprised if the early editions of to-morrow's evening papers contain the final sensation in this interesting case." He was gone before I could say another word, and all that I saw of him was his spook-like figure disappearing through the swing-door. There was no one now in the place, so a moment or two later I too paid my bill and went away. §5 The Old Man in the Corner proved to be right in the end. At eleven o'clock the next morning the street corners were full of newspaper placards with the flaring headlines: "Sudden death of Lord Foremeere." It was reported that on the previous evening his lordship was examining a new automatic which he had just bought and explaining the mechanism to his valet. At one moment he actually made the remark: "It is all right, it isn't loaded," but apparently there was one cartridge left in one of the chambers. His lordship, it seems, was looking straight down the barrel and his finger must accidentally have touched the trigger; anyway, according to the valet's story, there was a sudden explosion, and Lord Foremeere fell shot right between the eyes.
