As Caesar marches on Rome and panic erupts in the city, Gordianus the finder discovers, in his own home the body of Pompey's favourite cousin. Before fleeing the city, Pompey exacts a terrible bargain from the finder of secrets - to unearth the killer, or sacrifice his own son-in-law to service in Pompey's legions, and certain death. Amid the city's sordid underbelly, Gordianus learns that the murdered man was a dangerous spy. Now, as he follows a trail of intrigue, betrayal, and ferocious battles on a land and sea, the Finder is caught between the chaos of war and the terrible truth he must finally reveal.
