Kate stood wondering at their beauty, without the least idea that these oily swirls and boiling hummocks of smooth green water were among the most dangerous sea perils to be met with all the way from Pentland to Solway. Suddenly her eyes lit on a dark speck far away out upon the bright plain. It might have been the head of a swimming seal, or the black razor-edge of a large skerry showing over the rush of the tide. But, as she watched, the dot grew blacker and larger. A boat was certainly approaching the island. Kate stood trembling. For the issue meant life and death to her. It might be her tyrant come to claim his captive. It might be her saviour come to save. CHAPTER XXVII THE TIDE-RACE OF SULISCANNA Kate McGhie stood looking across the boiling, hillocky water of the Suck of Suliscanna in the direction of the boat, which moment by moment blackened and grew larger, rising steadily towards her out of the east. The day was so still, the tide so smooth as it swept inshore after passing the oily "bullers" of the roost, that she had no idea of the world of danger those in the adventurous bark had to pass before her prow could grate on the white sand of the landing-beach between the opposing headlands of Aionaig and Lianacraig. Kate's heart beat strangely, almost painfully. It was wonderful, she thought, that men should undergo perils and cross a world's seas for a simple girl's sake. Yet there was pleasure, too, in the thought; for somehow she knew that those who approached loved her and came from far seeking her good. "It is he--it is surely he!" so her soul chanted its glad triumph within her. "Did I not say that he could break prison-bands and come to find me--that he would overpass unruly seas only to look on my face? Has any maid in the world a lover true like mine? And he will break my prison also and take me away. And with him I am ready to go to the ends of the earth, fearlessly as though he had been my mother." Poor lassie! Little she knew the long, weary travel she had before her ere it could come to that. But even as she watched she became conscious of a quick stir and movement among the usually so indolent islanders behind her. Hardly she dared to lift her eyes from the approaching boat, which came on with a little square sail rigged on a temporary mast as long as the wind held, and then with flashing dips of rhythmic oars whenever the breeze dropped away. The voices of the men of Suliscanna crying harshly to each other among the craig-heads and cliff-edges high above her sounded to Kate's ears like a louder brawling of the sea-fowl. The sound had an edge on it, shrill, keen, and bitter as the east wind in mid-January. Yet there was something in it, too, of new. The girl had heard the like of it before, at the kennels of Cumlodan, when the bloodhounds for the Whig-tracking were waiting to be fed, and springing up with their feet on the bars.
