Beautiful young women are disappearing by the dozen. A celebration is cut short when a concerned father crashes Detective Inspector Lindsay Boxer's party. His daughter is missing - and she's not the only one. DI Lindsay Boxer has been tracking a chilling pattern: a Jane Doe washed ashore, a body in Golden Gate Park, a string of missing women across San Francisco. Someone is hunting the city's most vulnerable, and the count keeps rising. When Lindsay reaches out to Interpol, their warning is stark: these cases are nearly impossible to solve, and the women are almost never found alive. But 'impossible' has never stopped the Women's Murder Club before.
