Shadows of the Jackal

Between Spartacus and his freedom stands the gladiator Crixus, whose legend begins with his battle against the horrifying Gargan Twins. Feral, evil cannibals from birth, Decimus and Tiberius Gargan are finally captured and thrown in the arena, where they devour anything--and anyone--in their path. If Crixus can't stop them, there's no man alive who can!
