There was not a soul in sight. Not a sound to be heard save the purling waters of the little Cherry Brook on his left. He knelt down and washed the blood from his hand, then took a drink. And suddenly he laughed under his breath. It was good to be alive again—for he had not been living those past months in prison. He had been less alive than a caged animal. He had slept, eaten, worked, and exercised with mechanical-like precision. Even the agonies of mind he had undergone seemed unreal now. They did not even seem to matter—nothing mattered but the fact that he was free! Free to sit or stand, to walk or run, to laugh or to cry. Free to move as he liked, look where he liked, do what he liked. He dug his hands into the soft peat and tore it up, and sniffed the sweet scent. He stood upright and stretched out his arms, then laughed aloud. It was indeed good to be alive again. It was wonderful! The next moment he was trembling from head to foot, and his body broke out in a sweat. He was not to be alive for long. Even if he reached Blackthorn Farm and delivered his message he would have to give himself up and go back to prison. Back to that living grave! He had told poor 303 that escape was absolutely impossible. Even if a man got outside Dartmoor and reached Tavistock or Exeter or Plymouth he was certain to be detected and brought back. His father would never hide him or help him—he knew that. Yet if he once succeeded in getting home he could remain there hidden long enough to disguise himself, to grow a beard. And then one day, so altered as to be hardly recognisable, he might ship off to Canada or Australia. His head swam: he put his hands up before his eyes for a moment. The sudden draught of freedom had intoxicated him. Once again he gazed round the moorland. It was growing dark, the sun had set, and the western sky was still glowing red. Now and then a faint puff of wind stirred the trees surrounding the powder mill, and he saw stray banks of fog driving here and there, shifting their position. By crossing the stream he could step right into the white bank of mist. Freedom! The thought of it had become an obsession now. Taking a run he cleared Cherry Brook and plunged into the fog. He knew his way now; he could have found it blindfold. But he went cautiously, for no man can be sure of himself if he once misses his way when a Dartmoor fog is down. To reach Blackthorn Farm he would have to pass Post Bridge Hall, which lay between him and the East Dart. He kept edging towards the valley, for though it was near the main road, the fog lay more thickly there than in the higher ground.
