"That is as near as Fred can make it."
"Go on with your story," he said. "I'm interested in this. You were saying that Fred saw the lights go out, and then this woman came out of the house and walked away."
"Well, Fred got into the house through one of the windows at the side—the one Hill had told him to try," continued the girl. "But first of all he waited about half an hour in the garden, so as to give Sir Horace time to go to sleep. He was able to find his way about the house as Hill had given him a plan. He felt his way upstairs and finding a door open he went into the room and flashed his electric torch. By its light he saw Sir Horace Fewbanks lying huddled up in a corner with a big pool of blood beside him on the floor. He felt him to see if he was dead. The body was quite warm, but it was limp. Sir Horace was dead. Fred says he lost his nerve and ran for it as hard as he could. He rushed down stairs and out of the house and got back to the flat as fast as he could.
"The three of us sat there shaking with fear and wondering what to do. Hill was the first to recover himself. In his cunning plausible way, he pointed out that it was altogether unlikely that suspicion would fall on Fred or him. All we had to do was to keep quiet and say nothing; then we'd have no awkward questions put to us. It was his suggestion that we should send an anonymous letter to Scotland Yard telling them Sir Horace had been murdered. That would be much better, he said, than leaving the body there until he went over and found it when he had to go over to Riversbrook to take a look round, in accordance with the instructions that had been given him when Sir Horace went to Scotland. Knowing what he did, he was afraid that if he was allowed to discover the body and inform the police, he would let something slip when the police came at him with their hundreds of questions. We printed the letter to Scotland Yard, each one doing a letter at a time. Hill took it with him, saying he would post it on his way home.
"When he left, Fred and I sat there thinking. Suddenly it came to me as clear as daylight that Hill had committed the murder, and had fixed up things so as to throw suspicion on Fred. He must have known Sir Horace was coming back from Scotland that night, and he had laid in wait for him and shot him. Then he had come over to my flat in order to persuade Fred to carry out the burglary, and direct suspicion to Fred for the murder, if the police worried him. I told Fred what I thought, but he only laughed at me and said I was talking nonsense. But I was right, for a week afterwards the police came and arrested Fred at the flat."
"How did they get him?" asked Kemp.
"I saw them coming along the street from the window, and I pointed them out to Fred. He tried to get away through the kitchen window along the ledge and down the spouting. He almost got away, but one of the detectives saw him before he reached the ground, and they dashed down stairs and got him in the street. Next day I saw in the papers that Hill had made an important statement to the police, and this had led to Fred's arrest. Hill is the murderer, Kincher. The cunning, wicked, treacherous villain told the police about Fred being up there. He wants to see Fred hang in order to save his own neck." The girl's voice rose to a shriek, and she sprang to her feet with blazing eyes. "Kincher," she cried, "you've got to help me put the rope round this wretch's neck. Do you hear me?"
Kemp's impassivity was in marked contrast to the girl's hysterical excitement.
"What do you want me to do?" he asked.
"Fred wants you to get up an alibi for him. He sent me over to ask you to arrange it without delay. He wants you and two or three others to swear that he was over here on the night of the murder. That will be sufficient to get him off."
