Fiction. Mystery. Suspense. Thriller. In William Kent Krueger's "finest work" (Michael Connelly), detective Cork O'Connor unravels a mystery for his old friend Henry Meloux, only to get caught in the blistering crossfire of jealousy and revenge. The promise, as I remember it, happened this way. Happy and content in his hometown of Aurora, Minnesota, Cork O'Connor has left his badge behind and is ready for a life of relative peace, setting up shop as a private investigator. But his newfound state of calm is soon interrupted when Henry Meloux, an Ojibwe medicine man and Cork's spiritual adviser, makes a request: Will Cork find the son that Henry fathered long ago? With little to go on, Cork uses his investigative skills to locate Henry Wellington, a wealthy and reclusive industrialist living in Thunder Bay, Ontario. When a murder attempt is made on old Meloux's life, all clues point north across the border. But why would Wellington want his father dead? This question takes Cork on a journey through time as he unravels the story of Meloux's 1920s adventure in the ore-rich wilderness of Canada, where his love for a beautiful woman, far outside his culture, led him into a trap of treachery, greed, and murder. The past and present collide along the rocky shores of Thunder Bay, where a father's unconditional love is tested by a son's deeply felt resentment, and where jealousy and revenge remain the code among men. As Cork hastens to uncover the truth and save his friend, he soon discovers that his own life is in danger and is reminded that the promises we keep-even for the best of friends-can sometimes place us in the hands of our worst enemies.
