The master of making history fun, Terry Deary, tells the tales of fifty brutal betrayals across history. Did you know that the oldest story in the world is about the traitor Enkidu, who dared to rise up against King Gilgamesh? You might already know about Caesar and his unfaithful senators, but have you heard about Walter Tirel, the Norman knight who went out hunting with King William the Conqueror? Well, only one man returned. Walter claimed it was an accident, but he had a pretty good track record with his aim... There have always been people who are willing to switch sides, let down a friend, betray their country and turn traitor. Sometimes they do it for love, often because of their beliefs, maybe out of pride . perhaps even greed. (And sometimes just for fun.) Nothing could ever make you become a traitor though . could it?
