This true crime history delves into an unsolved murder in Victorian London that may have been the grim final act of Jack the Ripper. In the early hours of a cold February morning in 1891, the murdered body of Frances Coles was discovered beneath a railway arch in London's Swallow Gardens. The nature of her wounds, the weapon used to inflict them, and the murder site itself were clear indicators for many that London's most famous serial killer, Jack the Ripper, had returned. Whitechapel's notorious serial killer was thought to be long gone by the time of Frances Coles' death. The notion that he reappeared to complete his reign of terror was contentious then, and still is today. But there's no doubting the facts surrounding the killing are just as mysterious as those that involved the murders of Polly Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, Mary Jane Kelly and, intriguingly, several others. However, unlike in those previous cases, there was a serious suspect in the case of Frances Coles. Was that suspect the killer? And if so, did he have anything to do with any of the other Whitechapel murders? These questions have remained unanswered, until now.
