Following the events in Turks & Caicos (2014) Johnny Worricker and Margot Tyrell are in Europe trying to stay one step ahead of the Security Service. Through his old friend and colleague Rollo, he's managed to plant a story in The Independent about the source of the Prime Minister's "bridge" fund, but it gains little traction. Running low on cash, Worricker realizes that they'll have to go home. He pursues getting the story out by contacting The Independent's editor Belinda Kay and telling her the whole story. Meanwhile Jill Tankard, the head of MI-5, begins feeding information to Deputy Prime Minister Anthea Catcheside suggesting that the PM may be on his way out. For Worricker, he realizes too late that he too is a pawn in a much larger game.—garykmcd
