Michener developed four fictional pieces of land in Maryland to build the locations of his novel: Patamoke and The Neck; The Turlock Marsh; Peace Cliff; and Devon Island on which Rosalind's Revenge was built. All of these locations were placed by the open water of the Choptank. The location of Devon Island would be immediately north of Todds Point, approximately 3 miles southeast of the southern tip of Tilghman Island. The town of Patamoke lies on a fictitious promontory on the Choptank opposite Cambridge.
