force of ill, a moral and spiritual monster, and the more dangerous, because of a subtlety and resource which had kept him immune from the law. He outstripped the law, whose blood-hounds had no scent keen enough for him. He had broken the law, but always in such a way that there was not, and never could be, any proof. There had not been even suspicion. There had been knowledge on Gordon's part, and Mrs. Swing's, but knowledge without proof is more helpless than suspicion with it. The man was unassailable, free to go his way, working evil. Again Gordon thought he heard the nearing trot of a horse, and again the dog growled. Gordon was not quite sure that time that a horse had not passed the house. He told himself in despair that he could not be sure of knowing when James and Clemency came, and again the awful thought seized him, and again he reflected upon the man outside. Suppose, instead of wearing the semblance of humanity, he had worn the semblance of a beast, then his course would have been clear enough. Suppose it were a hungry wolf watching out there, instead of a man, and this man was worse than any wolf. He was like the weir-wolf of the old Scandinavian legend. He had all the cowardly cruelty of a wolf, he was a means of evil, but he had the trained brain of a man. Gordon thought he heard footsteps, and the man made a very slight motion. Gordon thought joyfully that Aaron had left the balky mare, and had returned, but it was not so. He had heard nothing except the pulsations of the blood in his own overwrought brain.
