Imperium Characters

Robert Harris

Rome's greatest orator takes on its most corrupt governor — armed only with words and a secretary's shorthand.

Part 2: The Crucified Citizen
Part 3: The Devil's Offer
Part 4: The Highest Office
Themes:
Words as weapons
The price of every favor
New man versus old blood
