Thus murdered she was found by her mother on her return, after inquiring in vain for the gentleman who was said to be waiting for her. Suspicion fell on Houssart, who was arrested and tried, but for want of the boy's evidence acquitted of the murder. But he was detained in Newgate to take his trial for bigamy. While waiting sentence, the boy, a lad of thirteen, who knew of the murder and arrest, and who thought he would be hanged if he confessed that he had carried the message to Mrs. Rondeau, came forward to give evidence. He was taken to Newgate into a room, and identified Houssart at once among seven or eight others. The brother of the deceased, Solomon Rondeau, as heir, now lodged an appeal, in the names of John Doe and Richard Roe (an ancient form of legal procedure), against Houssart, who was eventually again brought to trial. Various pleas were put forward by the defence in bar of further proceedings, among others that there were no such persons as John Doe and Richard Roe, but this plea, with the rest, was overruled, the fact being sworn to that there was a John Doe in Middlesex, a weaver, also a Richard Roe, who was a soldier, and the trial went on. The boy's evidence was very plain. He remembered Houssart distinctly, had seen him by the light of a lantern at a butcher's shop; he wore a whitish coat. The boy also recognized Mrs. Rondeau as the woman to whom he gave the message. Others swore to the white coat which Houssart had on; but the most damning evidence was that of a friend whom he had summoned to see him in Newgate, and whom he asked to swear that they had been drinking together in Newgate Street at the time the murder was committed. Houssart offered this witness a new shirt, a new suit of clothes, and twenty guineas to swear for him. The prisoner, however, owned that he did give the boy a penny to call the old woman out, and that he then went in and gave his wife "a touch with the razor, but did not think of killing her." The prisoner was found guilty and hanged at the end of Swan yard in Shoreditch.
