Blue/Orange

Blurb of the Published edition:
In a London psychiatric hospital, an enigmatic patient claims to be the son of an African dictator-a story that becomes unnervingly plausible. BLUE/ORANGE is an incendiary tale of race, madness and a Darwinian power struggle at the heart of a dying National Health Service.
(The blurb is not entirely accurate: the play does not situate itself in the NHS, and the patient's stories never appear to be very plausible, but this blurb serves as a good guide nonetheless for those curious.)
