While juggling a charming ex-fiancé, a friend with benefits, and a partner who is too darn handsome for his own good, Harlee begins socializing with the potential suspects outside of work...until the killer learns of her double identity. This mystery has a perfect blend of humor, sexiness, and suspense.
