Gillian Bradshaw's novel is set in Roman Britain at the time of the emperor Septimius Severus and the chief character, the African scout Memnon,is based on the protagonist in an incident said to have really happened to the emperor. It is a fine novel deserving of a wider readership. What did I like about this book? Memnon himself is human and humane, talented and flawed, a well rounded personality. The scene where he rescues the emperor's secretaries is tense, violent and exciting, yet realistic. The relationship which develops between these characters and other non Romans, such as the Caledonian and Pictish rebels allows the reader the opportunity to sympathise with the various peoples inside and outside the empire. The brutality of war, and the casual attitudes of those in command are not shirked. There is underlying tension and darkness to the plot, which does not follow predictable lines. However, it is rather episodic and some of the plot lines remain slightly underdeveloped, which cost it, in my opinion, the fifth star.
