“Anyway,” interrupted Penne, “even if you can’t be bought, you’re a secretive old devil, and that suits me. There’s a girl up at my house who is very ill. I don’t want any of these prying country doctors nosing around my private affairs. Would you come along and see her?” The old man pursed his lips thoughtfully. “I should be most happy,” he said, “but I am afraid my medical science is a little rusty. Is she a servant?” “In a way,” said the other shortly. “When can you come?” “I’ll come at once,” said Mr. Longvale gravely, and went out, to return in his greatcoat. The baronet looked at the ancient garment with a smile of derision. “Why the devil do you wear such old-fashioned clothes?” he asked. “To me they are very new,” said the old man gently. “The garments of to-day are without romance, without the thrill which these bring to me.” He patted the overlapping cape and smiled. “An old man is entitled to his fancies: let me be humoured, Sir Gregory.” At the moment Mr. Sampson Longvale was driving to Griff Towers, Mike Brixan, summoned by messenger, was facing Jack Knebworth in his office. “I hope you didn’t mind my sending for you, though it was a fool thing to do,” said the director. “You remember that we shot some scenes at Griff Towers?” Michael nodded. “I want you to see one that we took, with the tower in the background, and tell me what you think of—something.” Wonderingly, Michael accompanied the director to the projection room. “My laboratory manager pointed it out to me in the negative,” explained Jack as they seated themselves and the room went dark. “Of course, I should have seen it in the print.” “What is it?” asked Michael curiously. “That’s just what I don’t know,” said the other, scratching his head, “but you’ll see for yourself.” There was a flicker and a furious clicking, and there appeared on the small screen which was used for projection purposes, a picture of two people. Adele was one and Reggie Connolly the other, and Michael gazed stolidly, though with rising annoyance, at a love scene which was being enacted between the two. In the immediate background was the wall of the tower, and Michael saw for the first time that there was a little window which he did not remember having seen from the interior of the hall; it was particularly dark, and was lighted, even in daytime, by electric lamps. “I never noticed that window before,” he said. “It’s the window I want you to watch,” said Jack Knebworth, and, even as he spoke, there came stealthily into view a face.
