As she worked along the cliff above Dunbuy Haven, where the rock overhung the water, she seemed to increase both her interest and her caution. I followed round the rude wall which ran parallel to the cliff, so that I might be as near to her as possible. Dunbuy Haven is a deep cleft in the granite rock in the shape of a Y, the arms of which run seawards and are formed by the mother cliff on either hand and the lofty crags of the island of Dunbuy. In both these arms there is deep water; but when there is a sea on, or when the wind blows strong, they are supremely dangerous. Even the scour of the tide running up or down makes a current difficult to stem. In fair weather, however, it is fairly good for boating; though the swell outside may be trying to those who are poor sailors. I had often tossed on that swell when I had been out with the salmon fishers, when they had been drawing their deep floating nets. Presently I saw Gormala bend, and then disappear out of sight. She had passed over the edge of the cliff. I went cautiously after her, and throwing myself on my face so that she could not see me, peered over. There was a sort of sheep track along the face of the cliff, leading downward in a zigzag. It was so steep, and showed so little foothold, that even in the state of super-excitement in which I then was, it made me dizzy to look at it. But the old woman, trained on the crags of the western islands, passed along it as though it were the broad walk of a terraced garden. CHAPTER XLIX GORMALA'S LAST HELP After Gormala had disappeared down the zigzag under the rock, where I could no longer see her movements, I waited for her return. At the end of the Haven, where the little beach runs up to the edge of the cliff, there is a steep path. Even this is so steep that it is impracticable to ordinary persons; only fisher folk, dalesmen and hunters can use such ways. For myself I dare not leave my post; from the end of the Haven I could not see any part at all of the coast I had come to watch, except the narrow spot between great cliffs where the channels ran right and left of the Rock of Dunbuy. So I crept back to my hiding place behind the angle of the wall, from which I could watch the entrance to the track down which she had passed. Time wore away slowly, slowly; and the mist kept coming in more frequent belts, heavier and more dank. After the sunset the fog seemed to come more heavily still, so that the promise of the night was darkness invincible. In Aberdeen, however, the twilight is long, and under ordinary conditions it is easy to see for hours after sunset. All at once, after the passing of a belt of mist, I was startled by a voice behind me:
