"No, I think not--I thank you," the stranger answered jerkily. "You are welcome, if you will," persisted the carrier. "No, I think not. I think I will walk," the tall gentleman answered. But he still stood, and watched the other's preparations with strange intentness. Even when Nickson, having wished him good day, drove briskly off, he continued to gaze after the cart until a dip in the descent--not far below--swallowed it up. Then he heaved a sigh, and looked round at the grey sky and darkening heath. He took off his hat. "Hold up! what is the matter with the mare?" the carrier cried, coming to a stop as soon, as it chanced, as the dip in the road hid him from the other's eyes. "She has picked up a stone, drat it!" He got down stiffly, and taking his knife from his pocket went to the mare's head. Having removed the stone he dropped the hoof, and stood a second while he closed the knife. In this momentary pause there came to his ear a sharp report like that of a gun, but brisker and less loud. It was difficult to suppose it the sound of a snapping stick; or of one stone struck against another. It puzzled Master Nickson, who climbed hastily to his seat again and drove on until he was clear of the dip. Then, swearing at himself for an old fool, he looked anxiously back at the top of the ridge, which had come into view again. He was looking for the tall gentleman. But the latter was not to be seen, either standing against the sky-line or moving on the intervening road. "Lord's sakes!" the carrier muttered uneasily, "what has become of him? He cannot have gone back!" He continued to stare for some moments at the place where the stranger should have been. At last giving way to a sudden conviction, he got down from his cart, and, leaving it standing, hurried back through the dip, and so to the top of the ridge. The ascent was steep, and he was breathing heavily when he reached the summit and cast his eyes round him. No, the tall gentleman was not to be seen. The brown grass and heather stretched away on this side and that, broken by no human figure. Not even a rabbit was visible on the long white strip of road that in the far distance grew hazy with the fall of night. "The devil!" the carrier said, shuddering, and feeling more lonely than he had ever felt in his life. "Then he has gone, and----" He stopped. His eyes were on a dark bundle of clothes that lay a little aside from the road between two clumps of heather. Just a bundle of clothes it seemed, but Master Nickson drew in his breath at sight of it. The peewits and curlews had gone to rest. There was not a sound to be heard on the wide moor, save the beating of his heart.
