It's the mid-1960s and the British secret intelligence service is hit by a series of defection scandals. Facing considerable personal danger, Jane Moneypenny combines forces with 007 to try to smoke out a mole that she is convinced is buried deep in the heart of the Office. But as Bond is sacked and M forced into retirement, Moneypenny may have to find him alone.

Forty-two years later, Miss Moneypenny's niece and heir, Kate Westbrook, starts to suspect that her aunt's death was not an accident. She is sure the clues to what happened lie in the search for the mole. But as she pieces them together, she realises that there are significant forces determined to prevent her.

From the glamour of 1960s Jamaica to the treacherous beaches of the Outer Hebrides, Final Fling relates the thrilling adventures of the world's most famous secretary and reveals just how far people are prepared to go to defend - or betray - their beliefs.
