The Mystery of the Battersea Attacks

In 1837, Polly Adams and Mary Stevens were attacked by a mysterious man. The attacks left both women with serious injuries but also permanently traumatized. Three months later, the Lord Mayor of London received a letter from an unnamed aristocrat who claimed it had all been a prank put on as part of a dare. Researchers have speculated for over a century as to who the nobleman might have been, but no theories have ever panned out.
