Even in the gaslit murk of the Victorian London underworld they shocked...No other crimes have exerted such an appalled fascination as the grotesque killings of five Whitechapel prostitutes in 1888. And, until now no one has been able to unmask the real killer. Published as a companion to a gripping new television series, this is Mark Daniel's unforgettably convincing and atmospheric novelization of the jack the Ripper murders. With an added twist. Four separate ending expose four possible murderers. \One of these screenings will be screened at the end of the television series. You may agree with the conclusion or you may not.
