Simon Sharman is out for revenge, pursuing the assassin of his former colleague across war-torn Ukraine. Back in London, a Russian spy ring at the heart of the British Establishment remains active and a secret, yet desperate, struggle is underway to limit its attempts to sabotage the West's support for Ukraine.
On the battlefields of the Donbas, Simon may have a chance to locate the assassin but larger forces are at work and he finds himself sucked into a terrifying shadow conflict between Russia and the West.
Can a lone spy at war make a difference to the course of a conflict?
From the rubble strewn streets of Bakhmut to the meeting rooms of Whitehall, from dirty bombs to dirty politics, A Spy at War takes the reader behind the scenes of the war in Ukraine and the war for the hearts and minds of the international community.
