New York Times–bestselling author: An LAPD undercover cop goes missing in this crime novel by "one of the great American writers of our time" (Los Angeles Times).
There was never a better cop than Jungle Jack Herzog. A wiry man whose strength exceeded his frame, his ability to navigate the darkest corners of the City of Angels drew him repeated citations for bravery. Nicknamed the Alchemist for his uncanny ability to fake new identities, he did his best work as an undercover agent in the vice squad, disappearing into the underworld in the name of justice. Now he has disappeared for good.
It's a bad sign that Lloyd Hopkins catches Jungle Jack's case, because Hopkins works homicide. As he attempts to discover what happened to the missing cop, he investigates a strange murder committed with a revolver that predates the Civil War. There is a horrifying secret behind the cop's disappearance, but Lloyd Hopkins does not fear the truth.
