D. V. Bishop is the pseudonym of award-winning writer David Bishop. His love for the city of Florence and the Renaissance period meant there could be only one setting for his crime fiction. The first book in the Cesare Aldo series, City of Vengeance, won the Pitch Perfect competition at the Bloody Scotland crime writing festival and the NZ Booklovers Award for Best Adult Fiction Book. It was also shortlisted for the Wilbur Smith Adventure Writing Prize. Bishop was awarded a Robert Louis Stevenson Fellowship while writing that novel. He teaches creative writing at Edinburgh Napier University. Ritual of Fire is the third novel in the Cesare Aldo series following The Darkest Sin.

Set during a scorching Italian summer, Ritual of Fire is a historical crime novel set in 1530s Renaissance Florence and is the sequel to City of Vengeance and The Darkest Sin.
