Los Angeles, 1908. Anna Blanc is a former so-so socialite, a flailing police matron, and a killer detective.
Ex-heiress, Anna Blanc, is precariously employed by the Los Angeles Police Department, reforming delinquent children and minding lady jailbirds. What she really wants is to hunt criminals and be alone with Detective Joe Singer–both no-nos that could get her fired. On a lover’s tryst in Griffith Park, Anna and Joe discover the body of a young gambler. Anna can’t resist. She’s on the case. As her murder investigation stalls, and her police matron duties start piling up, strange floral arrangements begin arriving from an unknown admirer. Following the petals leads Anna to another crime–one close to home. Suddenly pitted against Joe, Anna must examine her loyalties and solve the crimes, even if it means losing the man she loves.
