The Roman Empire

Gaius Petrius Ruso is a divorced and down-on-his-luck army doctor who has made the rash decision to seek his fortune in an inclement outpost of the Roman Empire, namely Britannia. After a 36-hour shift at the army hospital, he succumbs to a moment of weakness and rescues an injured slave girl, Tilla, from the hands of her abusive owner. And before he knows it, Ruso is caught in the middle of an investigation into the deaths of prostitutes working out of the local bar.

The edge of the Roman Empire is a volatile place; the tribes of the North dwell near its borders. These hinterlands are the homeland of Gaius Petreius Ruso's slave, Tilla, who has scores of her own to settle there: Her tribespeople, under the leadership of the mysterious Stag Man, are fomenting a rebellion, and her former lover is implicated in the murder of a soldier. Ruso, once again pulled into a murder investigation, is appalled to find that Tilla is still spending time with the prime suspect.

At long last, Gaius Petreius Ruso and his companion, Tilla, are headed home - to Gaul. Having received a note consisting only of the words "COME HOME!" Ruso has (reluctantly, of course) pulled up stakes and brought Tilla to meet his family. But the reception there is not what Ruso has hoped for: no one will admit to sending for him, and his brother Lucius is hoping he'll leave.

Ruso and Tilla, now newlyweds, have moved back to Britannia, where Ruso's old friend and colleague Valens has promised to help him find work. But it isn't the kind of work he'd had in mind - Ruso is tasked with hunting down a missing tax man named Julius Asper. Of course, there's also something else missing: money. And the council of the town of Verulamium is bickering over what's become of it. Compelled to delve deeper by a threat from his old sparring partner, Metellus, Ruso discovers that the good townsfolk may not be as loyal to Rome as they like to appear.
