When he finally emerged from the inn, in no very pleasant temper, he caught sight, first, of the weekly steamer already half way up the loch, inward bound, and then of Sallie at a bend of the road in the distance, on her way back to the castle from the village. There was some one with her. It was Carthew.

Captain Dove became still more incensed, and, his mind a good deal inflamed by his recent potations, set off up the hill in pursuit of them, breathing noisily, not even pausing to scowl at the children who scurried indoors as he passed with the skirts of his long black coat streaming out behind him.

He had heard from Slyne that Herries, the factor, had formally appointed the young American his deputy until he should be able to undertake his own duties again. And, in spite of all Slyne and he could say to Sallie, she had obstinately refused to assist in getting rid of Carthew. He had heard from Slyne that Carthew was making far too many occasions for seeing her, and when he had cautioned Sallie on that score she had shown no disposition at all to take his advice.

"I've warned her often enough," he muttered with steadily rising wrath, "to quit monkeying with that fellow. And she'll get right out of hand now, unless I let her see, once and for all, who's going to be master here. Where would I come in if he managed to get married to her! He's got to go. That's all there is to it. I can't afford to have him hanging about here any longer."

The couple in front seemed to be in no hurry, however. He had almost overtaken them before he paused at a hazel-clump to cut himself a stout cudgel. By the time he had got that trimmed to his taste, they had almost reached the castle.

"I'll wait till she's gone in," said Captain Dove to himself. He had noticed that Carthew was carrying what looked like a woodman's axe. But that did not daunt him at all in his purpose. He lingered along the edge of an alder-thicket until at length Sallie shook hands in very friendly fashion with the young American and went her own way, while Carthew took to a trail through the woods and made off at a round pace, notwithstanding his limp, axe on shoulder, whistling blithely.

The path he was following wound in and out among plantations of pine and great groves of grey, leafless birches, until, at a distance of half a mile, it found the clear edge of the cliffs overlooking the circular inlet which forms the head of the loch, and finally faded away at the marge of a smooth plateau of bare rock enclosed on three sides by a thick tangle of woodland and rank undergrowth.

Captain Dove stalked him with all precaution, stepping from stone to stone among the wet snow which was rapidly melting, so that he might leave no traceable footprints on the soft, spongy soil or damp, dead leaves. And once, when Carthew halted to light a pipe, the old man, with murder in his mind, dropped into cover behind a moss-grown boulder at one side of the path—because that would have been a most unadvisable spot at which to attack a man armed with an axe. Then, as Carthew moved on, he once more took up the pursuit, through the clumps of bramble and bracken between the dark trunks of the firs about him.

Carthew stepped unconcernedly out of the dusk of the woods into the open space at the end of the path, and stopped there, axe on shoulder, to look about him. But Captain Dove did not immediately spring upon him as he had been minded to do, for he had just observed, at a corner of the convenient plateau, a round hut, stone-built and roofed with heather, which might or might not be inhabited. Captain Dove wormed his way round toward it, within the thicket.

The windows of the hut were shuttered and its door pad-locked on the outside. Captain Dove was delighted. He turned to squint across at Carthew from behind a bush and judge his distance, but still delayed his attack.
