Kidnapped in Venice by a Russian defector, Kate knows she's in trouble. But all is not as it seems. The spy offers her conclusive evidence that the British Prime Minister is a live agent working for Moscow. Kate’s holiday quickly becomes the start of her next mission. With proof of the PM involved in a sordid scandal and a financial paper trail that undeniably links him to the Russians, the evidence seems bulletproof. But the motives of the defector are anything but clear. And, more worryingly, it seems that there are key people at the heart of the British Establishment who refuse to acknowledge the reality in front of them.
