On the night of 24 March 1895. Mrs Robinson (Sheila Hancock) a society palm reader agreed to see Oscar Wilde in her London Flat. Wilde's lover, Lord Alfred Douglas, 'Bosie' was urging him to sue the Marquis of Queensberry (Bosie's father) for criminal libel. But Wilde's friends, wary of Quensberry's power, were warning him to leave town. In Extremis reveals the strange turmoil of that night, as a man at the height of his fame turns to a complete stranger for advice about a potentially life-changing decision.
