London, 1888. A monster prowls the gaslit streets, and the police are looking in all the wrong places, at all the wrong suspects. But three women refuse to stay silent. Emma, the chief detective’s sharp-witted wife, sees the investigation failing. Maggie, a private investigator, exposes men’s darkest secrets. Bet, a police station cleaner, overhears what others ignore. Together, they form an alliance to hunt down the killer dubbed Jack the Ripper. But as the women weave through the slums, brothels, and smoke-filled parlours of London’s underworld, they uncover corruption more sinister than they ever imagined. The city belonged to men – until now.
