Windsor Castle is a novel by William Harrison Ainsworth serially published in 1842. It is a historical romance with gothic elements. The focus of the novels is on the events surrounding Henry VIII's replacing Catherine of Aragon with Anne Boleyn as his wife. During Henry's pursuit of Boleyn, the novel describes other couples, including the Earl of Surrey and Lady Elizabeth Fitzgerald, a match Henry does not support. However, some of the individuals oppose Henry and his desires for Boleyn, including Thomas Wyat who wants her for himself and Cardinal Wolsey, who uses his own daughter, Mabel Lyndwood, to lure Henry away from Boleyn. Eventually, Wolsey turns to outting Wyat's desires for Boleyn to the Court, which almost results in Wyat's execution but is stopped before that point. Wolsey is then kicked out of the court and is executed himself. Intertwined with the Court is the story of Herne the Hunter, a spirit of Windsor Forest. He is an evil force that seeks to take the souls of various individuals, and Henry tries to stop him, but is never able to do so. Eventually, Wyat and Lyndwood are captured by Herne. The two fall in love and try to escape, but Mabel drowns. As the main plot progresses, Catherine accepts her fate but also warns Boleyn that Henry will treat her in the same way. It is revealed that Boleyn was involved with Henry Norris, and Henry uses this as evidence to have Boleyn executed. The story ends with Boleyn being replaced by Jane Seymour.
