In 1969 James Fox and Cyril Connolly began investigating the case for an article in "The Sunday Times" called "Christmas at Karen". When Connolly died in 1974 Fox inherited his notes and theories, and returned to Kenya to undertake further research. The result was the book "White Mischief", published in 1982. The title came from "Black Mischief", Evelyn Waugh's satirical novel set in the mythical African kingdom of Azania. "The New York Times" called it "a fascinating book." "The Boston Globe" said "had ‘White Mischief’ been a work of fiction it would have required the collaboration of Agatha Christie and P. G. Wodehouse." While researching the book Fox also collected information about Beryl Markham, which was turned into the film "".
