A fictionalized account of the conspiracies set around the murder of Julius Caesar at the dawn of his dictatorship, in which Calpurnia, Caesar's wife, hires Gordianus to save her husband, but he only agrees after his close friend was murdered for attempting to do the same task.
Gordianus, a young man in 92 B.C., embarks upon a voyage to see the Seven Wonders of the World with his tutor Antipater of Sidon, and along the way they encounter murder, witchcraft, and ghostly hauntings.
As the forces of Julius Caesar and Pompey the Great fight a bloody battle for supremacy, the city of Rome becomes a hotbed of intrigues, espionage, profiteering, and betrayals.
Gordianus the Finder, drawn back from the country to Rome to keep an eye on his patron Cicero's rival Catilina, is swept into a dangerous mystery when he discovers a headless corpse in his stables.
Gordianus the Finder is charged by Pompey the Great to discover what really happened on the Appian Way on January, 52 B.C. after Publius Clodius is found murdered and Titus Milo stands accused.
