Since Josslyn Hay, 22nd Earl of Erroll, was discovered dead in his car with a bullet through his head just outside Nairobi in 1941, speculation has not ceased as to the culprit and motive for his murder. The authorities seemed satisfied with the highly sensationalised trial of the only suspect, Jock Broughton, the cuckolded husband of Erroll’s last lover, Diana. A not-guilty verdict was returned after a baffling display of confusing evidence and clumsy police work. Trzebinski, who has lived in Kenya for 30 years, was not satisfied with the conflicting gossip on the case, none of whose evidence adds up, including that of the celebrated White Mischief by James Fox. In this gripping evocation of a glamorous, decadent and sinister life, Trzebinski uses her renowned biographer’s skill to unlock the mystique surrounding the man, and the mystery enveloping his death. Her investigations lead her to astonishing conclusions about the true motive for his murder and a conspiracy of confusion that finds its source in Whitehall’s War Office.
