It's the mid-1960s and the British secret intelligence service has been hit by a series of defection scandals. Facing considerable personal danger, Jane Moneypenny joins forces with 007 to try to smoke out a mole that she is convinced is buried deep in the heart of MI6. But when 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, begins to suspect that her aunt's death was not an accident. She is sure the answers to what happened lie in the search for the mole – somewhere between the glamour of Jamaica to the treacherous beaches of the Outer Hebrides. But as she pieces the clues together, she realises that there are significant forces determined to prevent her learning the truth . . . Final Fling is the last entry in Kate Westbrook's Moneypenny Diaries trilogy.
