When the keen air upon his bare head had driven him indoors, he sat down again to formulate his good resolutions, he found that his candles of expediency and morality had gone out.  The light which was there instead was the Presence of God; but so diffused was this light, so dim, that it was as hard for him now to see distinction between right and wrong as it would have been outside upon the snow to see a shadow cast by rays which had left their stars half a century before.  All, all of which he could think seemed wrong, because it was not God; all, all of which he could think seemed right, because it was part of God.  The young man’s face sank on his arms and lay buried there, while he thought, and thought, and thought, trying to bring a life of which he could think into relation with that which is unthinkable.

Was ever reverie more vain!  He raised his head and stared about him.  The glaring lamp showed all the details of the room, and made it seem so real, so much more real than mere thoughts, let alone that of which one cannot think.  He got up to alter the stove-damper, pushing it shut with a clatter of iron, burning his fingers slightly, and sat down again, feeling it a relief to know, if by the smart, that he had touched something.

The wood within the stove ceased blazing when the damper was shut, and when its crackling was silenced there was a great quiet.  The air outside was still; the flame of the lamp could hardly make sound.  Trenholme’s watch, which lay on the table, ticked and seemed to clamour for his attention.  He glanced down at it.  It was not very far from midnight.

Just then he heard another sound.  It was possibly the same as that which came to him an hour ago, but more continuous.  There was no mistaking this time that it was an unusual one.  It seemed to him like a human voice in prolonged ejaculatory speech at some distance.

Startled, he again looked out of his door.  At first he saw nothing, but what he had seen before—­the world of snow, the starry skies.  Yet the sound, which stopped and again went on, came to him as if from the direction in which he looked.  Looking, listening intently, he was just about to turn in for his coat and snow-shoes in order to go forth and seek the owner of the voice, when he perceived something moving between him and the nearest wood—­that very birch wood in which, more than a month before, he had sought for the man Cameron who had disappeared from his own coffin.  In an instant the mood of that time flashed back on him as if there had been nothing between.

All the search that had been made for Cameron in the first days of the snow had resulted in nothing but the finding of his coarse winding-sheet in this birch wood.  Then and since, confused rumours had come that he was wandering from village to village, but no one had been brave enough to detain him.  Trenholme knew that people on the railway line to the south believed firmly that the old man was still alive, or that his ghost walked.  Now, as his eyes focussed more intently upon the moving thing, it looked to him like a man.
