CHAPTER XVII.

AT POST BRIDGE HALL.

The warders stared into each other's faces.

"It's a bad job. You're sure he's dead----"

"I wouldn't have done it for anything," the man who had fired the shot whispered. "I aimed at his legs, too. Damn the gun!"

He threw it into the heather, and turned away to hide his emotion.

The second warder glanced back over his shoulder. The fog was slipping down the hillside again. The stone wall and the ponies were already lost to view.

"Fire off your gun again; they'll hear it on the road. I'd better go back for the ponies, or we shall lose 'em."

"Which way did the other fellow go?"

"I don't know. You get the ponies--I'll wait here."

The second warder hurried up the hillside towards the stone wall and disappeared into the fog. The one who had fired the fatal shot stooped to pick up his gun. As he did so, the figure of the convict lying on the heather stirred. A second later he was on his feet, running for dear life!

He was gone before the warder could realise what had happened. He swung round and stared open-mouthed at the wall of fog surrounding him on all sides.

"Well, I'm damned!" he ejaculated.

Jamming a cartridge into his gun, he fired it off.

* * * * *

When the fatal shot was fired Rupert was a few yards ahead of 303, and he felt a sharp sting at the point of his shoulder as he heard the shot whiz by. Thinking that the shot was aimed at him, and feeling himself hit, he swerved to the right and made for a low wall which ran down towards the powder-magazine, intent only on reaching its shelter. The shock of being fired at had put all thought of his comrade for the moment out of his mind, and it was not until he was over the wall and heading for the small clump of trees, through the top of which he could see the ruined chimney of the old powder-mill which instinct told him was his only chance, did he think of 303.

Slackening his pace, he glanced back over his shoulder--but he could see nothing. He turned once more and sped towards the trees which were now only a few hundred yards away, and the fold in the ground hid him from the road and also from the hill above. On reaching the trees, his breath coming in great gasps, worn out with excitement, he threw himself upon a bed of rushes growing beside the Cherry Brook, which flowed within the walls that enclosed the powder mills.

He was consumed with raging thirst, and when he had recovered his breath sufficiently, he crawled to the brook and buried his face in the cool, clear stream. As he sat up he saw his right hand dripping with blood, and for the first time remembered his wound. Taking off his broad-arrowed coat, he felt his throbbing shoulder, and was relieved to find the bullet had but grazed his flesh. He went to the stream and dipped his coat into the water--when he was startled by the dull thud of horses' hoofs approaching.

The powder mill buildings were mere ruined shells. There was no shelter there--but suddenly his eye caught the chimney, a circular stack about thirty feet high. The horseman had reached the wall; he heard him check the horse and dismount. Rupert remembered that he had often swarmed up the inside of the chimney when a boy. The sound of the pony's hoofs striking the stones of the wall as the warder led him through the gap caused Rupert to spring towards the chimney. In a second he was within the ruined furnace, grasping the iron bar which crossed the chimney some six feet above the ground.

He swung himself up, and placing his knees against the round wall in front of him, and with his back against the other side, he slowly worked himself up the narrow shaft until he was some twelve feet up. By jamming his feet in a niche from which the mortar had fallen out, and with his back thrust against the opposite wall, he made himself secure for the moment.

He heard the warder and the pony stumbling over the rubble which strewed the mouth of the ruined chimney; his heart was in his mouth. Pony and man were within the furnace, and the voice of the warder almost beneath him made Rupert look down in momentary expectation of meeting his upturned gaze; he saw his arm and shoulder already beneath the chimney--another moment he would be discovered.

A voice outside hailed the warder, and he stepped back--and disappeared.

For some little time Rupert heard the voice of men talking in the precincts of the powder mill. He strained his ears to try and hear what they said, but only caught odd words. He gathered that they were still searching both for him and Convict 303. He was relieved to know that his friend had not been caught; yet in his heart he realised it was only a matter of time. Once he reached home--if indeed he were lucky enough to succeed in doing so--he would only wait long enough to discover how things were with his father and sister, and to warn them that a fortune might still be lying within their grasp. He did not know how much of the little property had been mortgaged to Sir Reginald Crichton; he almost hoped the disused tin mine was included. As long as the interest was paid, the mortgage would remain undisturbed; and Sir Reginald had proved himself to be not only an upright gentleman, but a kind friend.

It was his one-time friend, Robert Despard, the man who had called himself his pal, whom he feared. Almost the last words the latter had spoken to him echoed ironically in his brain:

"I'll keep the secret about our radium mine, old man, never fear. It's safe with me!"

Various schemes flashed with lightning-like rapidity through Rupert's brain as he clung to his perilous position in the chimney above the furnace. He began to think that the men outside intended to remain there for the night--it seemed so long before they moved away, and he heard the beat of their ponies' hoofs growing fainter and fainter. But at last he knew they were really gone. Even then he waited awhile before he commenced to painfully clamber to the ground.

He was stiff and sore. His shoulder ached and throbbed where the stray buckshot had struck him. There was blood upon his hand, too, where he had cut it.

But he was still free. At first he moved cautiously, examining the country as much as was visible in all directions. The fog had partially cleared away, but it still lay in patches here and there.

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.

It was rough going. Rocks and boulders and gorse bushes impeded the progress, invisible in the mist. Now and again he struck a boggy patch of ground and had to make a wide detour to avoid it. He had been walking for upwards of an hour, and he began to fear lest he had missed his way and perhaps been going round in a circle, when suddenly he stepped out into a clear, starlit night. Below him he saw the tiny village of Post Bridge, and almost directly in front of him red lights gleaming through the belt of trees.

Post Bridge Hall! Down on the bridge itself, near the little post office, he saw figures moving to and fro. He dropped on to his hands and knees behind the shelter of a rock. He heard the barking of a sheep dog, the voices of men and women travelled up to him.

Of course the news of the escape had spread, and the place was alive with people searching.

How eager men and women were to hunt their kind! He remembered how as a boy he had joined in just such a hunt.

He commenced to crawl along on all fours towards Post Bridge Hall. The trees there might shelter him, but it would be useless to try and cross the patch of country on the other side. He climbed a couple of stone walls, crossed a field, scrambled over a fence, and dropped straight into the garden of the Hall itself.

Lights gleamed from the windows. The front door stood wide open, and not a hundred yards away from him he saw the outer door of the glass conservatory which abutted from the drawing-room. He saw with surprise that this was open too.

For a long time he lay waiting, watching, afraid to go on--because he knew the fog would not descend again. The million eyes of the night watched him from a cloudless sky.

Presently from the woods behind him he heard voices and the barking of dogs. A gang of men were beating the spinney, searching for the two convicts.

Within sight of home he would be caught. He rose to his feet, crossed the narrow stretch of turf and walked boldly up the drive.

He stood a moment outside the conservatory door, listening. He heard nothing but the voices of the men in the wood and the barking of the dogs.

He stepped inside the conservatory, closed the door, and then, fumbling for the key, found it. He locked it, and drew the bolts top and bottom which he knew were there. Stooping down he crawled beneath the broad shelf which ran the length of the glass-house. The leaves of a palm and the fronds of a large fern gave him complete shelter.

He stretched himself out full length so as to lie perfectly flat, and as he did so his foot struck a pile of empty flower-pots. They fell over with a crash. He stopped breathing. He thought he detected a woman's voice in the drawing-room. A minute passed, but no one came.

He breathed again. He was safe for the time being. The conservatory door was locked. They would never search Sir Reginald Crichton's house! He was still a free man. And freedom to him now was more than anything else in the world. More than love or honour, or the wealth that might be lying hidden in the tin mine at home, waiting for his father and sister.
