Blood Debts. Leonidas the Gladiator Mysteries

Leonidas, freeman, former slave gladiator and champion of the Roman Colosseum, now must fight the full might of the Roman Empire.  A man who owed him money was murdered, and Leonidas is a prime suspect.  With the formidable assistance of Cassia, a greek scribe who is also his unwanted slave, Leonidas fights the treachery of justice in the courts and back lanes of Imperial Rome.  And if he loses, he faces a short, painful future back in the Colosseum, without friends, arms, or hope.
