It was already night when I shut the halldoor behind me and stepped out on to the soft white covering which was already thick on the ground. The snow was still falling thickly, and the only sound I heard, as I groped my way under the arching trees of the avenue, was the occasional swishing noise of a load of snow that, dislodged by a fresh burden from the upper branch of a fir-tree, brushed the lower boughs as it fell to the earth. I am constitutionally untroubled by nervous tremors, and I was too deeply occupied with thoughts of Fabian and his wife to give much grave consideration to possible danger from the unhappy lunatic who was now in all probability hidden somewhere in the neighbourhood with a weapon in his possession; but when in the oppressive darkness and stillness the tramp of footsteps in the soft snow just behind me fell suddenly on my ears, I confess that it was with my heart in my mouth, as the dairymaids say, that I turned and raised threateningly the thick stick I carried. It was, however, only Jock, gun in hand as usual, who had run fast to overtake me, and had come upon me sooner than he expected, the small lantern he carried in his hand being of little use in the darkness. 'What made you come, Jock?' I asked, not, to tell the truth, sorry to have a companion upon the lonely forest road which seemed on this night, for obvious reasons, a more gloomy promenade than usual. 'Mistress Scott bid me gang wi' ye, sir,' answered he. 'She said the necht was sae dark ye might miss the pairth by the burn.' We walked on together in silence until, having left the avenue far behind us, we were well in the hilly and winding road which runs through the forest from Loch Muick to the Dee. At one of the many bends in the roadway Jock suddenly stopped and stood in a listening attitude. 'Deer?' said I. 'Nae,' answered he, after a pause, in a measured voice, 'It's nae deer.' He said no more, but examined the barrels of his gun by the light of the lantern, and walked on at a quicker pace. I had heard nothing, but his manner put me on the alert, and it was with a sense of coming adventure that, peering before me in the darkness and straining my ears to catch the faintest sound, I strode on beside the sturdy young Highlander. Warned as I was, it was with a sickening horror that, a moment later, I too heard sounds which had already caught his keener ears. Muffled by the falling snow, by the intervening trees, there came faintly through the air the hoarse yelping cries of a madman. I glanced at the stolid figure by my side. 'Was that what you heard, Jock?' I asked stupidly, more anxious for the sound of his voice than for his answer. 'I dinna ken, sir, if ye heard what I heard,' said he cautiously.
