MI6 operative Luke Carlton returns in his most exciting and unnervingly up-to-the-minute mission yet . . . this is the new edge-of-your-seat spy thriller from the bestselling author.
In the dying light of an Arctic afternoon a monstrous black shape slips beneath the waters of Murmansk bay. Murmansk in the Arctic Circle is where Russia’s fleet of nuclear-powered submarines is based – and the Novorossiya is one of their navy’s most advanced – and dangerous – vessels . . .
Acting on information received from a high-ranking mole deep inside Russia’s FSB, Britain’s security services are convinced that the submarine is about to deploy a terrifying, game-changing device. As Europe goes into a state of high alert, MI6 operative Luke Carlton is sent into the hot zone that is the Finnish-Russian border. His mission to secure the safe extraction of this valuable MI6 asset and the intel he has in his possession – because it seems the West could be staring Armageddon in the face.
It’s then that things start to go devastatingly wrong . . .
