Stephanie Theobald Stephanie Theobald (born 29 August 1966) is a British novelist and journalist, author of "Biche" and three other novels. The Times described her as “One of London’s most celebrated literary lesbians.” She was dubbed a “notorious lesbian author” by the "Daily Mail" in 2007. In a "Varsity" 2011 interview with Theobald the paper described her as “No ordinary female writer.” She has been the subject of controversy – punk designer Vivienne Westwood is a vociferous anti-fan of Theobald’s work. At a London society party in 2009 she approached her to announce that she ‘hated’ Theobald’s novels adding that "A Partial Indulgence" was “Like vomit coming at you off the page.”
