Through the heather the two swung, the Master thinking now with a smile of David and Maggie; wondering what M'Adam had meant; musing with a frown on the Killer; pondering on his identity--for he was half of David's opinion as to Red Wull's innocence; and thanking his stars that so far Kenmuir had escaped, a piece of luck he attributed entirely to the vigilance of Th' Owd Un, who, sleeping in the porch, slipped out at all hours and went his rounds, warding off danger. And at the thought he looked down for the dark head which should be travelling at his knee; yet could not see it, so thick hung the pall of night. So he brushed his way along, and ever the night grew blacker; until, from the swell of the ground beneath his feet, he knew himself skirting the Giant's Chair. Now as he sped along the foot of the rise, of a sudden there burst on his ear the myriad patter of galloping feet. He turned, and at the second a swirl of sheep almost bore him down. It was velvet-black, and they fled furiously by, yet he dimly discovered, driving at their trails, a vague hound-like form. “The Killer, by thunder!” he ejaculated, and, startled though he was, struck down at that last pursuing shape, to miss and almost fall. “Bob, lad!” he cried, “follow on!” and swung round; but in the darkness could not see if the gray dog had obeyed. The chase swept on into the night, and, far above him on the hill-side, he could now hear the rattle of the flying feet. He started hotly in pursuit, and then, recognizing the futility of following where he could not see his hand, desisted. So he stood motionless, listening and peering into the blackness, hoping Th' Owd Un was on the villain's heels. He prayed for the moon; and, as though in answer, the lantern of the night shone out and lit the dour face of the Chair above him. He shot a glance at his feet; and thanked heaven on finding the gray dog was not beside him. Then he looked up. The sheep had broken, and were scattered over the steep hill-side, still galloping madly. In the rout one pair of darting figures caught and held his gaze: the foremost dodging, twisting, speeding upward, the hinder hard on the leader's heels, swift, remorseless, never changing. He looked for a third pursuing form; but none could he discern. “He mun ha' missed him in the dark,” the Master muttered, the sweat standing on his brow, as he strained his eyes upward. Higher and higher sped those two dark specks, far out-topping the scattered remnant of the flock. Up and up, until of a sudden the sheer Fall dropped its relentless barrier in the path of the fugitive. Away, scudding along the foot of the rock-wall struck the familiar track leading to the Scoop, and up it, bleating pitifully, nigh spent, the Killer hard on her now. “He'll doon her in the Scoop!” cried the Master hoarsely, following with fascinated eyes. “Owd Un! Owd Un! wheer iver are yo' gotten to?” he called in agony; but no Owd Un made reply.
