One of Britain's leading historians Guy de la Bedoyere is the author of a widely admired series of books on Roman history and has appeared on progammes including Channel 4's Time Team and Channel 5's Pompeii Live. His critically- acclaimed new book tells the story of the Praetorian Guard who defended the Roman Emperors from Augustus to Constantine, exploring the history of Imperial Rome through their eyes. Vivid and accessible - and told with clarity and panache - Guy's story of the Praetorian Guard is 'warmly recommended both to aspiring tyrants and ordinary armchair historians' - The Sunday Times.
