A handsome and charismatic Greek tragedy professor at Cambridge University, Edward 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 on The Maidens when one member, a friend of Mariana’s niece Zoe, is found murdered in Cambridge. She becomes convinced that, despite his alibi, Edward Fosca is guilty of the murder. When another body is found, Mariana’s obsession with proving Fosca’s guilt spirals out of control, threatening to destroy her credibility as well as her closest relationships.
