On Saturday, February 20, 1892 Wilde's play Lady Windermere's Fan premiered in London at the St. James Theatre.Lady Windermere's Fan follows the life of a high society wife (Lady Windermere) who suspects her husband is unfaithful. She devises a plot to catch him in his infidelity, invites his mistress to a birthday party, and finds herself in a tenuous half-friendship with the woman before it's revealed she is (spoiler alert) Windermere's own mother. The play was well received by audiences. This came at a stark contrast to his first two plays, Vera, or The Nihilists and Duchess of Padua, which were marked failures that Wilde acknowledged as such. Wilde's Lady Windermere's Fan earned a triumphant review from the St. James Gazette, who wrote, "the play, it need hardly be stated, has been superbly mounted, every detail being cared for with praiseworthy taste and liberality".
