Sir Anthony Blunt is the director of the Courtauld Institute, London. While cleaning a Titian painting, Blunt has discovered a potential forgery in the Royal Collection. But the painting isn't the only fake - Blunt himself is a spy, the soon-to-be infamous 'fourth man' in the Cambridge Spy Ring. Playing on the concept of fakes, Bennett's drama explores deception, loyalty and artifice in British society, exposing the muddy waters of Cold War era politics and government. 'A Question of Attribution' premiered at the Royal National Theatre, London, in December 1988.
