According to Hilary and her brother Piers in their book A Genius in the Family (released in America as Hilary and Jackie), the affair was conducted with Hilary’s consent as a way of helping Jacqueline through a nervous breakdown. Reportedly, Hilary asked Jacqueline to sleep with Kiffer during her separation from Barenboim. In 1999 Clare Finzi, the daughter of Kiffer and Hilary, publicly criticised her mother’s account and laid out a different version of events, in which her father was a serial adulterer who seduced her emotionally vulnerable aunt in a time of great need in order to gratify his own ego.
Anand Tucker’s controversial 1998 film Hilary and Jackie is based on A Genius in the Family, and features Emily Watson as Jacqueline and Rachel Griffiths as Hilary. Although it was a critical and box-office success, even getting an Academy Award nomination, the film was derided by du Pre’s close friends and associates as being completely untruthful of the person they knew.
