“That was the starting point of the book, and then I became ill, I had gallstones removed. But when I came out of the hospital, I came back to work with Mike and he had struck something which I had not really thought about.
“He had re-organised the book and made it more compelling. It kept changing shape, and in the end, we had a book that was not like a normal biography but it’s about a family.
“It’s about a remarkable man, my father, but it’s more than that, it’s about family life,” he added.
