Dr. Jekyll invents a drug that changes him into the ominous Mr. Hyde. His evil nature, however, becomes the stronger part of him and to his horror, he no longer needs the formula to transform his appearance. Weir of Herimston: Set in the time of the Napoleonic Wars, this tells the story of Archie Weir, a youth born into an upper-class Edinburgh family. Because of his Romantic sensibilities and sensitivity, Archie is estranged from his father. By mutual consent, Archie is banished from his family of origin and sent to live as the local laird on a family property in the vicinity of the Borders hamlet Hermiston. While serving as the laird, Archie falls in love.
