In April 1961, shortly before the second court case on "Thunderball", Fleming had a heart attack during a regular weekly meeting at "The Sunday Times". While he was convalescing, one of his friends, Duff Dunbar, gave him a copy of Beatrix Potter's "The Tale of Squirrel Nutkin" and suggested that he take the time to write up the bedtime story that Fleming used to tell to his son Caspar each evening. Fleming attacked the project with gusto and wrote to his publisher, Michael Howard of Jonathan Cape, joking that "There is not a moment, even on the edge of the tomb, when I am not slaving for you"; the result was Fleming's only children's novel, "Chitty-Chitty-Bang-Bang", which was published in October 1964, two months after his death.
