As a private investigator, Kathleen Stone relies on her ability to blend into the background. With a little help from the best wigmaker on the Atlantic seaboard, Kathleen can take on a variety of personas, from a posh real estate agent to a petulant teenage boy. She was once a valuable undercover cop for the New York City Police Department, but since her early retirement following a botched case, she has gone a little soft. These days, with the assistance of a street-smart drag queen, she mostly catches cheating spouses in flagrante. When one husband ends up not so much adulterous as dead, Kat must tune up her rusty skills to catch a killer.

She begins investigating the upper echelons of New York, a city that can swing from glamorous to lethal in an instant. She soon finds herself stepping on the toes of her former best friend, Detective Ellis Dekker, as well as a sadistic kingpin she hoped to never see again. Not only do memories of Salvatore Magrelli's knife-friendly tendencies give her the heebie-jeebies, but his connection to the case makes Kat a possible suspect, too. She needs to move fast...if she is to avoid becoming the next victim.
