NEW YORK CITY, 1925.
By day, Penny Fox runs The Sly Fox detective agency, helping women escape dangerous marriages and catching philandering husbands in the act.
By night, Penny manages The Primrose, the glittering cabaret and speakeasy she inherited after her father's sudden death--a venue that exists at the mercy of mob boss Sonny Hargrave.
As if juggling two dangerous professions wasn't enough, Penny finds herself falling for Cora Bellinger, a woman she rescued from an abusive relationship--complicating Penny's already precarious engagement.
But when the dancers from her cabaret begin disappearing and their bodies later discovered, Penny realizes a serial killer is stalking the women of The Primrose. Now she must use every detective skill she possesses to catch a murderer before he claims another victim.
In a world where women are expected to know their place, Penny Fox refuses to back down--even when facing the deadliest threat of all.
