Between May 1887 and February 1891, a succession of horrific murders shook Victorian London. The police at the time believed these crimes against women were perpetrated by two unrelated killers, yet much of the evidence was deposited in the authorities' Jack the Ripper file. No one was ever prosecuted for these crimes and no convincing suspect has been put forward. Taking a fresh look at the facts, Drew Gray and Andrew Wise arrive at an original, convincing explanation that finds the individual who had the means, motive, and opportunity.
