God's Spy

God's Spy (Espía de Dios in Spanish) is a bestselling thriller novel by Juan Gómez-Jurado originally published in Spain in 2006, and in English in 2007. It has become an instant bestseller throughout Europe with a million copies sold to date and is going to be published in 42 countries. The plot is set in the Vatican, where, in the aftermath of Pope John Paul II's death, the hunt for a serial killer and sex offender — and former priest — reveals a chilling conspiracy. It is a detective story where the psychological portrait of Victor Karosky, the serial killer (whose name is known from the first line of the book) is the spine of the novel. The action also takes place in a Maryland institution called the Saint Matthew Institute, a center for the rehabilitation of priest with a history of sexual abuse, which is based on a real-life place. This subject has aroused controversial issues in Catholic countries as Spain and Poland.
