"Saylor puts such great detail and tumultuous life into his scenes that the sensation of rubbing elbows with the ancients is quite uncanny."--"The New York Times Book Review" "Saylor's scholarship is breathtaking and his writing enthrals."--Ruth Rendell, "Sunday Times" (London) "An excellent blending of mystery and history."--"Library Journal" "Saylor writes about ancient Rome as naturally and comfortably as if he had lived there, capturing both its glory and brutality.
