He remembered well how first the notion of killing her came into his head, just a little seed, small as that of mustard, which lay long in barrenness. Only the bare idea of it was there, like an abstract proposition. Then imperceptibly in the fruitful darkness of his mind, it must have begun to sprout, for presently a tendril, still soft and white, prodded out into the daylight. He almost pushed it back again, for fear that she, by some divining art, should probe his purpose. But when next she came for supplies, he saw no gleam of surmise in her red-rimmed eyes, and she took her money and went her way, and his purpose put forth another leaf, and the stem of it grew sappy. All autumn through it had flourished, and grown tree-like, and fresh ideas, fresh details, fresh precautions, flocked there like building birds and made it gay with singing. He sat under the shadow of it and listened with brightening hopes to their song; never had there been such peerless melody. They knew their tunes now, there was no need for any further rehearsal. He began to wonder how soon he would be back on the road again, with face turned from this buffeting wind, and on his way home. His business would not take him long; the central deed of it would be over in a couple of minutes, and he did not anticipate delay about the setting to work on it, for by seven o’clock of the evening, as well he knew, she was usually snoring in the oblivion of complete drunkenness, and even if she was not as far gone as that, she would certainly be incapable of any serious resistance. After that, a quarter of an hour more would finish the job, and he would leave the house secure already from any chance of detection. Night after night during these last ten days he had been up here, peering from the darkness into the lighted room where she sat, then listening for her step on the stairs as she stumbled up to bed, or hearing her snorings as she slept in her chair below. The out-house, he knew, was well stocked with paraffin; he needed no further apparatus than the whipcord and the matches he carried with him. Then back he would go along the exact route by which he had come, re-entering the village again from the eastwards, in which direction he had set out.
