"Closer."
Colwyn bent his head nearer, and those standing by could see the dying man whispering into the detective's ear. He spoke with an effort for some minutes, and hurriedly, like one who knew that his time was short. Then he stopped suddenly, and his head fell back grotesquely, like a broken doll's. Colwyn felt his heart, and rose to his feet.
CHAPTER XXIX
"There are several things that I do not understand," said Superintendent Galloway to Colwyn a little later. "How were you able to decide so quickly that Benson had told the truth when he declared that he had not committed the murder, after he had made the damning admission that he had removed the body?"
"Partly because it was extremely unlikely that Benson could have invented a story which fitted so nicely with the facts. The slightest mistake in his times would have proved him to be a liar. But I had more than that to go upon. I said this afternoon that my reconstruction was not wholly satisfactory, because there were several loose ends in it. At that time I believed he was the murderer, and I was anxious to frighten the truth out of him in order to see where my reconstruction was at fault. His story proved that my original conception of the crime was the correct one, and my mistake was in departing from it, and ignoring some of my original clues in order to square the new facts with a fresh theory. I should never have lost sight of my first conviction that there were two persons in Mr. Glenthorpe's room the night he was murdered.
"When Benson told his story I asked myself, Could Charles' conduct be dictated by the desire to have a hold over Benson—with a view to blackmail later on? But he was not likely to risk his own neck by becoming an accomplice in the concealment of the murdered man's body! Charles, if he were innocent himself, must have thought that Benson was the murderer. It was impossible that he could have come to any other conclusion. He discovers a man washing blood off his hands at midnight, and this man admits to him that he has just come from a room which he had no right to enter, and found a dead man there. Why had Charles believed—or pretended to believe—Benson's story?
"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.
