Detroit debutante-turned-investigative journalist Iris Edwards gets more truth than she can handle when she tackles her rich and infamous grandfather's tell-all biography. By accepting his challenge to find his "Unforgivable Sin" and write the true story of his life, she'll have to unravel a web of Machiavellian intrigues dating back to the days of copper mines, gangsters, and rum-runners to find a deadly secret that could rewrite history.Joe Falcon, the governor's Native American physician, is on his own quest for the truth. He's lived his whole life in shadow of the powerful Edwards family, and with the old man's death, Iris becomes his only hope to solve his mother's thirty year-old murder. But before their childhood friendship can grow into something more, they'll have to understand Andrew Edwards' world; where, "Winning was everything and whoever carried the biggest stick won the game." With only a charred pocket watch and clues hidden in half-forgotten bedtime stories, they dodge Iris' gangster-wannabe ex-husband to trace his life from an Upper Peninsula ghost town to an insane asylum and the Henry Ford Museum--to find a killer, a hero, and the real meaning of truth, love and sacrifice.
