"It came to me suddenly, with the recollection of the line under the murdered man's window--one of the clues which I had discarded--and the whole of this baffling sinister mystery became clear in my mind. The murder was committed by Charles, who got out of the window by which he had entered just before Benson came into the room. Charles saw a light in the room he had left, and returned to the window to investigate. Crouching outside the window, he saw Benson in the room, examining the body, and it came into his mind as he watched that his employer had conceived the same idea as himself--had seized on the presence of a stranger staying at the inn in order to rob Mr. Glenthorpe, hoping that the crime would be attributed to the man who slept in the next room. Charles was quick to see how Benson's presence in the room might be turned to his own advantage. Charles had taken precautions, in committing the murder, to leave clues in the room which should direct suspicion to Penreath, but the innkeeper's visit to the room suggested to him an even better plan for securing his own safety. When Benson left the room Charles got through the window again, and followed him downstairs. "Charles' story, told to me when he was dying, filled in the gaps which I have omitted. He said that he watched the whole of Benson's movements from the window. He saw him searching for the money, saw him feel the body, and saw the blood on his hands. When Benson turned to leave the room he forgot the candle, and it was then that the idea of following him leapt into Charles' mind. He divined that Benson would go downstairs and wash the blood off his hands. Charles' idea was to go after him and surprise him in the act. He followed him swiftly, and was never more than a few feet behind. While Benson was striking a match and lighting the kitchen candle Charles slipped into his own room, lit his own candle, and then emerged from his door as though he had been disturbed in his sleep. The rest of his plan was easily carried out through the fears of Benson, who agreed, in his own interests, to conceal the body of the man whom the other had murdered. "The clue by which Penreath was virtually convicted--the track of bootmarks to the pit--was an accidental one so far as Charles was concerned. It is strange to think that Chance, which removed the clues Charles deliberately placed in the room, should have achieved Charles' aim by directing suspicion to Penreath in a different, yet more convincing manner. "The murderer's revelation clears up those points which I was unable to settle this afternoon. He entered Mr. Glenthorpe's room during the heaviest part of the storm. He carried a box, under his arm, because he was too short to get into the window without something to stand on, he shielded himself from the rain with an umbrella, which got caught on the nail by the window, and he lit a tallow candle which he had brought from the bar.
