The King Must Die is the story of Theseus, hero of Greek myth, but addressed through the lens of the real-world archeological record. The story removes the mythical elements of Theseus's journey and substitutes a more realistic narrative without monsters, gods, or supernatural events. It follows Theseus from his childhood in Troizen and throughout his life as a wandering soldier, sailor, and merchant until he reaches Naxos where he reigns as king in his prime.
