After two years in the Seattle Police Department, homicide detective Alice Madison has finally found a measure of peace she has never known before—a sense of belonging. When a local burglary escalates into a gruesome murder, Madison takes charge of the investigation, only to discover that this is no ordinary killing. She finds herself tracking a serial assassin who has haunted the city for years—and whose brutality is the stuff of legend among the super-max prisons of the Pacific Northwest. As she delves deeper into the case, Madison learns that the widow of one of the victims is being stalked—is the killer poised to strike again? As pressures mount, Madison will stop at nothing to save the next innocent victim, but when her own past comes under scrutiny from enemies close to home, Madison's position on the force—and the fate of the case itself—are suddenly thrown into jeopardy.
