All aboard for a fast-paced, Jazz Age–era murder mystery set aboard a Chicago-bound train! It’s 1923, and thirteen-year-old Bobby Lee Claremont is leaving the Sisters of Charitable Mercy orphanage in New Orleans, certain a better life awaits in Chicago’s glamorous-sounding mob scene. But his plans unravel when he boards his train and meets the recently widowed Nanette O’Halloran, her two traveling companions, and a cop who suspects the trio of murdering Nanette’s husband. Bobby Lee is sure Nanette’s innocent. But what about her companions? As Bobby Lee digs for answers, he discovers the mob, Prohibition, segregation, and a famed jazz band are all pieces of an increasingly dangerous puzzle. A Junior Library Guild selection.
