Retired Chicago detective Leo Townsend's quiet suburban life is shattered when his obsessive-compulsive neighbor, Arthur Pendelton, vanishes—leaving behind a cryptic envelope addressed to Leo containing a motel key card and a menacing text about "the missing hour." Ignoring police orders to stay uninvolved, Leo follows the trail to a seedy lakeside casino town, where he uncovers a thirty-two-year-old murder, a dying cop's deathbed confession, and a kidnapper desperate to bury the truth forever. A gripping, human-hearted thriller about justice, redemption, and second acts.
