An exceptionally talented undercover policewoman, Grace Flint nearly dies in a botched sting operation. Months later, physically healed but psychologically scarred, she gets an unexpected clue about her attacker, and disappears on a mission of revenge - unaware that she is about to pull the first string that will unravel a vastly complex web of international treachery, extortion, and murder.
Pursuing her, using whatever clues he can find, is Harry Cohen, the former chief legal advisor to the British Security Services, who has been drawn back in as an impartial outsider because everybody is worried about Flint's safety. Or are they?

For there are many kinds of betrayal, and some of them are worse than others . . . Download and start listening now!
