1180 BC. Young Acheron is a liar. Everybody knows it. Troy is under siege and Acheron tells tales of Trojan bravery to entertain Prince Paris and the beautiful Helen at the palace. But when a stranger comes to the city to announce that the Greeks have departed, leaving a special gift of a wooden horse, Acheron is suspicious. He races to tell Prince Paris about the Greek plot, but will anyone at the palace believe him? Er, no, actually! As Aesop said, "There is no believing a liar, even when he speaks the truth."
