A woman ahead of her time, Molly Murphy is determined to be a private detective. Having inherited the cases of her deceased mentor, Paddy Reilly, she's following philandering husbands, tracking down a runaway Dublin debutante, and working in a sweatshop to discover who's purloining dress designs. None of her jobs seem dangerous...at first. When a woman's body is fished out of the East River, Molly fears it's the missing society girl. Then Molly's sometime beau, police captain Daniel Sullivan, reveals that another corpse may be the girl's scalawag lover, Mike Kelly. But Molly has to know their identities for certain. Now as threads of passion and greed weave a tapestry of violence, Molly descends into the underworld of the gangs of New York. It's no place for a lady, and even a scrappy Irish lass may need more than her street smarts to get the truth...and get out alive.
