The Mephisto Club

About “The Mephisto Club”

A Latin phrase scrawled in blood at the scene of a young woman's murder—I HAVE SINNED—draws Boston medical examiner Maura Isles and Detective Jane Rizzoli into a case linked to controversial psychiatrist Joyce O’Donnell, a member of the Mephisto Club. This secret group studies the nature of evil, exploring whether it has a scientific explanation or a physical presence, and delves into dark historical data and religious symbolism to support their theory that Satan exists among them. A corpse appears on the club's doorstep, suggesting a killer is at large. The club members grow fearful, wondering if the killer is one of their own or if they have awakened something dangerous. Maura and Jane investigate the most unsettling case of their careers, facing a malevolent force more terrifying than anything they have encountered before.
