In the confession he described how, some days before the burglary, he had, according to his custom, "spotted" the house at Whalley Range. In order to do this he always dressed himself respectably, because he had found that the police never suspected anyone who wore good clothes. On the night of the crime he passed two policemen on the road to the house. He had gone into the grounds and was about to begin operations when he heard a rustle behind him and saw a policeman, whom he recognised as one of those he had met in the road, enter the garden. With his well-known agility Peace climbed on to the wall, and dropped on to the other side, only to find himself almost in the arms of the second policeman. Peace warned the officer to stand back and fired his revolver wide of him. But, as Peace said, "these Manchester policemen are a very obstinate lot." The constable took out his truncheon. Peace fired again and killed him. Soon after the murderer saw in the newspapers that two men had been arrested for the crime. "This greatly interested me," said Peace. "I always had a liking to be present at trials, as the public no doubt know by this time." So he went to Manchester Assizes and saw William Habron sentenced to death. "People will say," he said, "that I was a hardened wretch for allowing an innocent man to suffer for the crime of which I was guilty but what man would have given himself up under such circumstances, knowing as I did that I should certainly be hanged?" Peace's view of the question was a purely practical one: "Now that I am going to forfeit my own life and feel that I have nothing to gain by further secrecy, I think it is right in the sight of God and man to clear this innocent young man." It would have been more right in the sight of God and man to have done it before, but then Peace admitted that during all his career he had allowed neither God nor man to influence his actions. How many men in the situation of Peace at the time, with the certainty of death before him if he confessed, would have sacrificed themselves to save an innocent man? Cold-blooded heroism of this kind is rare in the annals of crime. Nor did Peace claim to have anything of the hero about him. "Lion-hearted I've lived, And when my time comes Lion-hearted I'll die." Though fond of repeating this piece of doggerel, Peace would have been the last man to have attributed to himself all those qualities associated symbolically with the lion.
