The scene is the village of Lyme Regis on Dorset's Lyme Bay..."the largest bite from the underside of England's out-stretched southwestern leg." The major characters in the love-intrigue triangle are Charles Smithson, 32, a gentleman of independent means & vaguely scientific bent; his fiancée, Ernestina Freeman, a pretty heiress daughter of a wealthy & pompous dry goods merchant; & Sarah Woodruff, mysterious & fascinating...deserted after a brief affair with a French naval officer a short time before the story begins.
