Divorced and down on his luck, Gaius Petreius Ruso has made the rash decision to seek his fortune in an inclement outpost of the Roman Empire, namely Britannia. In a moment of weakness, after a straight thirty-six hour sift at the army hospital, he succumbs to compassion and rescues an injured slave girl, Tilla, from the hands of her abusive owner. Now he has a new problem: a slave that won't talk, can't cook, and drags trouble in her wake. Before he knows it, Ruso is caught in the middle of an investigation into the deaths of prostitutes working out of the local bar. Now Ruso must summon all his forensic knowledge to find a killer who may be after him next.
