When Patrick OConnor went missing in August 1849, his friends were suspicious. The London dock worker was last seen in the company of Swiss-born Maria Manning and her husband in Bermondsey. By the time police officers discovered his remains under the kitchen floor, the couple had fled. This shocking crime sparked a race against time to bring these cold-blooded killers to justice. After almost a decade of unsolved murders in the capital, could Scotland Yard detectives find the murderous pair and restore public confidence in their sleuthing skills? The search for the Mannings spread beyond England and was closely followed by the Victorian public, including prominent writers such as Charles Dickens who was haunted by the case and later immortalised some of the key characters in _Bleak House_, which was published just four years later. To this day, the Bermondsey Murder remains a legendary crime in the history of Scotland Yard and mid-nineteenth century London. Using primary source material,this book delves into the background of the Mannings, including Marias link with royalty and Fredericks previous criminal activities. It also offers a full biography of the victim, Patrick OConnor, and his shady past, as well as presenting the original court documents which shed further light on the case and the Mannings' relationship.
