But in the rooms under the roof in Bloomsbury it was different, for there it was perfectly clear to Jones that Thorpe had come to take up his abode with him. He never saw him, but he knew all the time he was there. Every night on returning from his work he was greeted by the well-known whisper, "Be ready when I give the sign!" and often in the night he woke up suddenly out of deep sleep and was aware that Thorpe had that minute moved away from his bed and was standing waiting and watching somewhere in the darkness of the room. Often he followed him down the stairs, though the dim gas jet on the landings never revealed his outline; and sometimes he did not come into the room at all, but hovered outside the window, peering through the dirty panes, or sending his whisper into the chamber in the whistling of the wind. For Thorpe had come to stay, and Jones knew that he would not get rid of him until he had fulfilled the ends of justice and accomplished the purpose for which he was waiting. Meanwhile, as the days passed, he went through a tremendous struggle with himself, and came to the perfectly honest decision that the "level of a great forgiveness" was impossible for him, and that he must therefore accept the alternative and use the secret knowledge placed in his hands--and execute justice. And once this decision was arrived at, he noticed that Thorpe no longer left him alone during the day as before, but now accompanied him to the office and stayed more or less at his side all through business hours as well. His whisper made itself heard in the streets and in the train, and even in the Manager's room where he worked; sometimes warning, sometimes urging, but never for a moment suggesting the abandonment of the main purpose, and more than once so plainly audible that the clerk felt certain others must have heard it as well as himself. The obsession was complete. He felt he was always under Thorpe's eye day and night, and he knew he must acquit himself like a man when the moment came, or prove a failure in his own sight as well in the sight of the other. And now that his mind was made up, nothing could prevent the carrying out of the sentence. He bought a pistol, and spent his Saturday afternoons practising at a target in lonely places along the Essex shore, marking out in the sand the exact measurements of the Manager's room. Sundays he occupied in like fashion, putting up at an inn overnight for the purpose, spending the money that usually went into the savings bank on travelling expenses and cartridges. Everything was done very thoroughly, for there must be no possibility of failure; and at the end of several weeks he had become so expert with his six-shooter that at a distance of 25 feet, which was the greatest length of the Manager's room, he could pick the inside out of a halfpenny nine times out of a dozen, and leave a clean, unbroken rim.
