Out of her depth, Martha no longer knows who can be trusted.Escaping failure as an undergraduate and a daughter, not to mention bleak 1970s England, Martha marries Kit - who is gay. Having a wife could keep him safe in Moscow in his diplomatic post. As Martha tries to understand her new life and makes the wrong friends, she walks straight into an underground world of counter-espionage. "Sarah Armstrong has delivered a mesmerising, evocative novel in which characterisation and narrative tension are in perfect balance." BARRY FORSHAW
