Purgatory Ridge: a Cork O'Connor mystery

"Not far from Aurora, Minnesota (population 3,752), lies an ancient expanse of great white pines, sacred to the Anishinaabe tribe. When an explosion kills the night watchman at wealthy industrialist Karl Lindstrom's nearby lumber mill, it's obvious where suspicion will fall. Former sheriff Cork O'Connor agrees to help investigate, but he has mixed feelings about the case. For one thing, he is part Anishinaabe. For another, his wife, a lawyer, represents the tribe. Meanwhile, near Lindstrom's lakeside home, a reclusive shipwreck survivor and his sidekick are harboring their own resentment of the industrialist. And it soon becomes clear to Cork that harmony, both at home and in Aurora, will be on the back burner for some time."--Back cover.
