Plot summary
Indy and Remy work aboard a ship as they sail from Mexico to Ireland on their way to London to join the war. In Dublin, Indy meets a girl called Maggie, her brother Seán Lemass, and her friend Nuala, then learns some things from local playwright Seán O'Casey. Indy and Seán take a disliking to each other even after Maggie dumps him when she finds out Indy isn't an American millionaire after all, and Indy gets into a fight with Seán before they see the pointlessness of fighting and become friends. The Easter Rising breaks out and, though most of the rebels are shot, Seán is imprisoned.
