"I saw through my father’s eyes ‘the bravest man I ever hanged’, the soldier who had come home from the South African War and found his wife unfaithful. He carried his little daughter in his arms up the stairs of his North London home, and cut her throat, and then tore down the decorations which had been put up for his return, and took a Union Jack from them and placed it over the child’s body. Then he went to the police and gave himself up. They asked why he had done it. ‘So that she would not grow up like her mother,’ he replied."
