The man who cast two shadows

Detective Kathleen Mallory is a brilliant but socially detached hacker-turned-cop who operates by her own rules in the heart of New York City. When a woman is found murdered wearing Mallory's own clothes, the investigation becomes a personal hunt for a killer who seems to know her every move. She must navigate a web of deception and her own dark past to find the truth before the shadow of the killer catches up to her.
