Gabriel Dax, travel writer and accidental spy, is back in the shadows. Unable to resist the allure of his MI6 handler, Faith Green, he has returned to a life of secrets and subterfuge. Dax is sent to Guatemala under the guise of covering a tinderbox presidential election, where the ruthless decisions of the Mafia provoke pitch-black warfare in collusion with the CIA.

As political turmoil erupts, Gabriel's reluctant involvement deepens. His escape plan leads him to West Berlin, where he uncovers a chilling realisation: there is a plot to assassinate magnetic young President John F. Kennedy. In a race against time, Gabriel must navigate deceit and danger, knowing that the stakes have never been higher.
