The Assassini
Thomas Gifford
 Set in 1982, while the Roman Catholic Church's papal conclave is preparing to elect a new pope as the old one is dying, the book describes the attempts of lawyer Ben Driskill to solve the murder of his sibling, Sister Valentine, a nun who was an outspoken activist and a thorn in the Church's side. Driskill's world-spanning investigation leads him to the discovery of a document from a forgotten monastery in Ireland, which proves the existence of the Assassini, an age-old brotherhood of killers, once hired by princes of the Church to protect it in dangerous times; and the person who now controls them in his Machiavellian bid for power.
