“For dinner--exactly. I want everything to be there that was present on the night of the tragedy; everything. Naturally you will have to place different flowers in the vases, but I want to see the same vases. From the soup tureen to the serviette rings, Benson, I wish you to duplicate the dinner table as I remember it, paying particular attention to the exact position of each article. Mrs. Howett will doubtless be able to assist you in this.” “Very good, sir,” said Benson--but his voice betokened bewilderment. “I will see Mrs. Howett at once, sir.” “Right. Good-bye.” “Good-bye, sir.” Replacing the receiver, Harley took a bunch of keys from his pocket and, crossing the office, locked the door. He then retired to his private apartments and also locked the communicating door. A few moments later he came out of “The Chancery Agency” and proceeded in the direction of the Strand. Under cover of the wire-gauze curtain which veiled the window he had carefully inspected the scene before emerging. But although his eyes were keen and his sixth sense whispered “Danger--danger!” he had failed to detect anything amiss. This constant conflict between intuition and tangible evidence was beginning to tell upon him. Either his sixth sense had begun to play tricks or he was the object of the most perfectly organized and efficient system of surveillance with which he had ever come in contact. Once, in the past, he had found himself pitted against the secret police of Moscow, and hitherto he had counted their methods incomparable. Unless he was the victim of an unpleasant hallucination, those Russian spies had their peers in London. As he alighted from a cab before the house of the late Sir Charles, Benson opened the door. “We have just finished, sir,” he said, as Harley ran up the steps. “But Mrs. Howett would like to see you, sir.” “Very good, Benson,” replied Harley, handing his hat and cane to the butler. “I will see her in the dining room, please.” Benson throwing open the door, Paul Harley walked into the room which so often figured in his vain imaginings. The table was laid for dinner in accordance with his directions. The chair which he remembered to have occupied was in place and that in which Sir Charles had died was set at the head of the table. Brows contracted, Harley stood just inside the room, looking slowly about him. And, as he stood so, an interrogatory cough drew his gaze to the doorway. He turned sharply, and there was Mrs. Howett, a pathetic little figure in black. “Ah, Mrs. Howett,” said Harley; kindly, “please try to forgive me for this unpleasant farce with its painful memories. But I have a good reason. I think you know this. Now, as I am naturally anxious to have everything clear before Miss Abingdon returns, will you be good enough to tell me if the table is at present set exactly as on the night that Sir Charles and I came in to dinner?”
