It was eleven o’clock when he crossed the fields to the postern gate, on the alert all the time for the soft-footed Bhag. The postern was closed and locked—a contingency for which he was prepared. Unstrapping his bag, he took therefrom a bundle of rods, and screwed three together. To the top he fastened a big, blunt hook, and, replacing the remainder of the rods, he lifted the hook till it rested on the top of the high wall, tested its stability, and in a few seconds had climbed his “ladder” and had jumped to the other side. He followed the path that he had taken before, keeping close to the bushes, and all the time watching left and right for Penne’s monstrous servant. As he came to the end of the hedge, the hall door opened and two men came out. One was Penne, and for a moment he did not recognize the tall man by his side, until he heard his voice. Mr. Sampson Longvale! “I think she will be all right. The wounds are very peculiar. It looks almost as if she had been scratched by some huge claw,” said Longvale. “I hope I have been of assistance, Sir Gregory, though, as I told you, it is nearly fifty years since I engaged in medical work.” So old Longvale had been a doctor! Somehow this news did not surprise Michael. There was something in the old man’s benevolence of countenance and easy manner which would have suggested a training in that profession, to one less analytical than Michael Brixan. “My car will take you down,” he heard Sir Gregory say. “No, no, thank you; I will walk. It is not very far. Good night, Sir Gregory.” The baronet growled a good night and went back into the dimly-lit hall, and Michael heard the rattle of chains as the door was fastened. There was no time to be lost. Almost before Mr. Sampson Longvale had disappeared into the darkness, Michael had opened his canvas bag and had screwed on three more links to his ladder. From each rod projected a short, light, steel bracket. It was the type of hook-ladder that firemen use, and Michael had employed this method of gaining entrance to a forbidden house many times in his chequered career. He judged the distance accurately, for when he lifted the rod and dropped the hook upon the sill of the little window, the ladder hung only a few inches short of the ground. With a tug to test the hook, he went up hand over hand, and in a few seconds was prying at the window sash. It needed little opening, for the catch was of elementary simplicity, and in another instant he was standing on the step of a dark and narrow stairway.
