was married to someone else at the time; the relationship fuelled Aldous Huxley's jealousy. During the 1920s, Arlen rented rooms opposite 'The Grapes' public house in Shepherd Market, then a bohemian Mayfair address. He later used Shepherd Market as the setting for The Green Hat. Fame and fortune After "The London Venture", Arlen worked on romances, spicing them with elements of psychological thrills and horror, including The Romantic Lady, These Charming People, and "Piracy": A Romantic Chronicle of These Days. In These Charming People, for instance, Arlen wrote tales which included elements of fantasy and horror, in particular "The Ancient Sin" and "The Loquacious Lady of Lansdowne Passage". The volume also introduced a 'gentleman crook' reminiscent of Raffles in the story "The Cavalier of the Streets". The title of another story, "When a Nightingale Sang in Berkeley Square", was the inspiration for the popular song of the same name. These works culminated in the book that would launch Arlen's fame and fortune in the 1920s: The Green Hat, published in 1924. The Green Hat narrates the short life and violent death of Iris Storm, a femme fatale and dashing widow, the owner of a yellow Hispano-Suiza as well as the green hat of the title. Arlen adapted the novel for a 1925 Broadway play, starring Katharine Cornell and Leslie Howard in his most successful Broadway appearance to date. An almost simultaneous but less successful adaptation in London's West End starred Tallulah Bankhead. The book figures in A Question of Upbringing by Anthony Powell as representative of life in Shepherd Market. The novel was adapted for the silent 1928 Hollywood film A Woman of Affairs starring Greta Garbo and John Gilbert. The Green Hat was considered provocative in the United States; hence, the movie was not allowed to make any references to it. The film obscured or altered plot points in the novel concerning homosexuality and venereal disease. It was adapted a second time in 1934, as Outcast Lady, with Constance Bennett and Herbert Marshall in the main roles. After the publication of The Green Hat, Arlen became almost instantly famous, rich, and as with celebrities today, incessantly in the spotlight and newspapers. During this period of his fame, the mid-1920s, Arlen frequently travelled to the United States and worked on plays and films, including Dear Father and These Charming People. According to Noël Coward's biographer Sheridan Morley, in 1924 Arlen
