In the late 1950s the author Geoffrey Jenkins had suggested to Fleming that he write a Bond novel set in South Africa, and sent him his own idea for a plot outline which, according to Jenkins, Fleming felt had great potential. After Fleming's death, Jenkins was commissioned by Bond publishers Glidrose Productions to write a continuation Bond novel, "Per Fine Ounce", but it was never published. Starting with Kingsley Amis's "Colonel Sun", under the pseudonym "Robert Markham" in 1968, several authors have been commissioned to write Bond novels, including Sebastian Faulks, who was asked by Ian Fleming Publications to write a new Bond novel in observance of what would have been Fleming's 100th birthday in 2008.
