Timewatch (1982) : 7x7

Bizarre theories have surrounded the unexplained killings in Whitechapel since they hit the headlines in 1888. This film dispels the grisly fiction, revealing for the first time the true contents of the police and Home Office files on the case, drawing on the expertise of historians and of those who have encountered today's killers - on the street or behind bars. Revisiting the sites of the crimes, piecing together evidence from Victorian locations across London, the invention of the legend becomes clear, as Christopher Frayling unravels the circumstances which turned a killer into a Gothic hero.
