In this "smart and satisfying" (Booklist) award-winning mystery from William Kent Krueger's stunning Cork O'Connor series, the charismatic detective faces his most dangerous case to date.

Back in the saddle as sheriff of Tamarack County, Cork O'Connor is lured to the nearby Ojibwe reservation on what appears to be a routine call--only to become the target of sniper fire. Soon after, he's called to investigate a mutilated body found perched above the raging waters of Mercy Falls. The victim is Eddie Jacoby, a Chicago businessman negotiating an unpopular contract between his management firm and the local Indian casino.

Sparks fly when the wealthy Jacoby family hires a beautiful private investigator to consult on the case. But once Cork discovers an old and passionate tie between one of the Jacoby's sons and his own wife, Jo, he begins to suspect that dark, personal motives lurk behind recent events. Murder, greed, sex, and jealousy hide around every corner in this maze of danger. But somewhere beneath the turbulent Mercy Falls lies the truth--and Cork is determined to find it.
