So we mounted shoulder after shoulder of heathery hillside, like vessels that labour over endless billows of the sea against a head wind. The thunder cloud which seemed to brood upon the outer circle of the hills, and arch over the country of Macaterick and the Star, now grumbled nearer and louder. Not seldom there came a fierce, white, wimpling flash, and the encompassing mountains seemed ready to burn up in the glare. Then ensued darkness blacker than ever, and the thunder shaking the world, as though it had been an ill-builded house-place with skillets and pans clattering on the wall. We had been thus walking for some while, bearing breast to the brae all the time, and leaning forward even as a horse leans to its collar. We came in time near to the height of the pass. We could not see a yard before us. But suddenly we felt the ground begin to level in front; and lo! in a moment we were in the throat of the defile, with the hills black above us on either side. Suddenly there came a terrible white flash of lightning, brighter and longer continued than any we had seen. The very air seemed to grow blue-black like indigo. The thunder tore the heavens, galloping without ceasing. Flash followed rending flash. Immediately before us on a hillock we saw a wondrous sight. There sat Gash Gibbie, the mis-shaped idiot, crouched squat like a toad, at the head of a woman who lay with her arms straight at her sides, as though stretched for burial. As we stood illumined against the murky blackness of the pass, the monstrous thing caught sight of us, and waved his hands, dancing meantime (as it seemed) upon spindles of legs. How he had come so far and so swiftly on such a night I cannot tell. But without doubt, there he was on the highest rock of the pass, with the dead woman stretched at his feet, and the fitful blue gleam of the lightning playing about him. And I warrant you it was not a comely or a canny sight. "Come ye here," cried the idiot lad, wavering above us as though he were dancing in the reek of the nether pit, "an' see what Yon has done to my mither. I aye telled her how it wad be. It doesna do to strive wi' Yon. For Yon can gie ye your paiks so brave and easy. But my mither, she wad never hear reason, and so there she lies, dead streeked in the 'Nick o' the Deid Wife.' YON has riven the life frae my mither!" We were close at his side by this time, and we saw an irksome sight, that shook our nerves more than the thunder. A woman of desperately evil countenance lay looking past us, her eyes fixed with an expression of bitter wrath and scorn upon the black heavens. Her face and hands were stained of a deep crimson colour, either by the visitation of God or made to seem so by the flickering flame of wild-fire that played about us. CHAPTER XLIII. THE VENGEANCE OF "YON." Gash Gibbie surveyed the sight with a kind of twisted satisfaction. He went hirpling about the body round and round. He squatted with crossed legs at its head.
