It's 1888 -- the Autumn of Terror. Jack the Ripper is brutally murdering prostitues in Whitechapel, the poorest section of London. The police bungle the investigation and are stumied. Quee Victoria is pushing them to solve the case. Lady Sarah, a disgraced arisstocrat who runs a boarding house, takes up the quest as her own misfortunes weigh on her. Along with her brother, other aristocrats and the prostitutes who rent from her, Sarah doggedly follows the trail at her own personal peril. As the murders grow even more grisly, Lady Sarah's chase takes a number of twists and turns, like the streets of Whitechapel itself.
