Atticus by Ron Hansen

Colorado rancher Atticus Cody receives word that his wayward younger son, Scott, has committed suicide in Resurrection, Mexico. When Atticus travels south to recover Scott's body, he is puzzled by what he finds there and begins to suspect murder. Illuminating those often obscure chambers of the human heart, Atticus is the story of a father's steadfast and almost unfathomable love for his son, a mystery that Ron Hansen's fiction explores with a passion and intensity no reader will be able to resist.
