He turned the folded sheet over and saw on the addressed side of it the postmark Hintondean, and the prosaic detail “2d. to pay.” He got up slowly, leaving his lunch unfinished—the letter had come by the one o’clock post—and went into his study. He rang for his housekeeper, and told her to go round the house at once, examine all the fastenings of the windows, and close all the shutters. He closed the shutters of his study himself. From a locked drawer in his bedroom he took a little revolver, examined it carefully, and put it into the pocket of his lounge jacket. He wrote a number of brief notes, one to Colonel Adye, gave them to his servant to take, with explicit instructions as to her way of leaving the house. “There is no danger,” he said, and added a mental reservation, “to you.” He remained meditative for a space after doing this, and then returned to his cooling lunch. He ate with gaps of thought. Finally he struck the table sharply. “We will have him!” he said; “and I am the bait. He will come too far.” He went up to the belvedere, carefully shutting every door after him. “It’s a game,” he said, “an odd game—but the chances are all for me, Mr. Griffin, in spite of your invisibility. Griffin _contra mundum_ ... with a vengeance.” He stood at the window staring at the hot hillside. “He must get food every day—and I don’t envy him. Did he really sleep last night? Out in the open somewhere—secure from collisions. I wish we could get some good cold wet weather instead of the heat. “He may be watching me now.” He went close to the window. Something rapped smartly against the brickwork over the frame, and made him start violently back. “I’m getting nervous,” said Kemp. But it was five minutes before he went to the window again. “It must have been a sparrow,” he said. Presently he heard the front-door bell ringing, and hurried downstairs. He unbolted and unlocked the door, examined the chain, put it up, and opened cautiously without showing himself. A familiar voice hailed him. It was Adye. “Your servant’s been assaulted, Kemp,” he said round the door. “What!” exclaimed Kemp. “Had that note of yours taken away from her. He’s close about here. Let me in.” Kemp released the chain, and Adye entered through as narrow an opening as possible. He stood in the hall, looking with infinite relief at Kemp refastening the door. “Note was snatched out of her hand. Scared her horribly. She’s down at the station. Hysterics. He’s close here. What was it about?” Kemp swore. “What a fool I was,” said Kemp. “I might have known. It’s not an hour’s walk from Hintondean. Already?” “What’s up?” said Adye. “Look here!” said Kemp, and led the way into his study. He handed Adye the Invisible Man’s letter. Adye read it and whistled softly. “And you—?” said Adye. “Proposed a trap—like a fool,” said Kemp, “and sent my proposal out by a maid servant. To him.” Adye followed Kemp’s profanity. “He’ll clear out,” said Adye. “Not he,” said Kemp.
