Colthurst said of the experience, "She was enormously enthusiastic to have her story out there, she knew exactly what she was doing. He brought her questions from Morton and recorded tapes of her answers to bring back to him. In 1991, Colthurst conducted secret interviews with the Princess of Wales in which she talked about her marital issues and difficulties. Colthurst was a "middle-man" between Diana and Morton, who wrote the biography on the princess. In October 1986, while escorting the Princess of Wales on an official royal visit to St Thomas' Hospital where she opened a new CT scanner in James Colthurst's X-ray department, he met royal journalist Andrew Morton. At the time of publication, Buckingham Palace denied any cooperation between the princess and Morton, but it was later revealed that Diana was the main source behind the book's content. The book was controversial as it detailed out Diana's suicidal unhappiness within her marriage and her struggles with depression. The book was published in the United Kingdom in hardcover format on 16 June 1992 by Michael O'Mara Books.
