The past never stays buried in Chicago. When retired detective Frank Mallory receives a rain-soaked envelope containing a photograph of a woman who died twenty years ago, old ghosts come clawing back. Ellie Walsh was a nightclub singer with a voice that could stop a room cold. Her murder was ruled solved. The city moved on. Mallory never did. Driven by guilt and unfinished business, he digs back into the case and uncovers something worse than a mistake — a lie. One that points to his former partner… and a department that wanted the truth buried. What begins as a cold case turns into a dangerous hunt through Chicago's underbelly of dirty cops, fading loyalties, and long-hidden secrets. Because someone is still watching. And they'll kill to keep the past quiet. Perfect for fans of gritty noir, slow-burn mysteries, and hardboiled detective fiction. The Last Case of Detective Mallory is a sharp, atmospheric crime novella about memory, justice, and the cost of the truth.
