Leo Sable runs a Boston gallery specializing in macabre history. When railroad heir Arthur Pendleton arrives with a mysterious letter from a 19th-century artist, Leo is drawn into a century-old murder. The discovery of a painting hidden in the Pendleton attic—depicting a young woman with a broken neck—unravels a dark family secret. With help from Leo's researcher father and a descendant of the victim, they uncover evidence of twelve murdered women, their deaths covered up by Boston's elite. A haunting mystery about justice, memory, and ghosts that refuse to stay buried.
