Today we speak of an 'Achilles' heel'. But who was Achilles, and what exactly was the story of his heel? Why was he considered the finest hero in the Trojan War, and what caused him to fall out with King Agamemnon so that he refused to fight? Did he survive the war, or was he killed? All these questions are answered in this Put it in Your Pocket booklet, the fourth in a series of six on the Trojan War.
