Unable to make any progress in locating the missing Indavara, a desperate Cassius has been given an unrewarding assignment in Antioch. But when an old ally's daughter is kidnapped, he feels duty-bound to repay a long standing debt. Disillusioned with the tawdry demands of the Imperial Security Service, he disobeys his superiors and leaves Syria, determined to do some good.
Accompanied by nomadic chieftain Kabir and a trio of warriors, Cassius soon finds himself in Greece hunting a vicious band of slave-traders trafficking women across the Empire. But these are no common criminals, and as Cassius sets out to bring them down, he finds himself up against ruthless, cunning men with powerful friends and a lot to lose.
For the Agent of Rome, desperate times call for desperate measures.
