Edward Fosca is a murderer. Of this Mariana is certain. But Fosca is untouchable. A charismatic Greek Tragedy professor at Cambridge University, Fosca is adored by staff and students alike. Particularly by the members of a secret society of female students known as The Maidens. Mariana Andros is a brilliant but troubled group therapist who becomes fixated when one of The Maidens, a friend of Mariana's niece Zoe, is found murdered. Mariana, who was once herself a student at the university, suspects that behind the idyllic beauty of the spires and turrets, lies something sinister. And she becomes convinced that, despite his alibi, Edward Fosca is guilty of the murder. But why would the professor target one of his students?
