Sentinel : A Spycatcher Novel

With the US and Russia on the brink of war, Will Cochrane - the master spy introduced in the critically acclaimed SPYCATCHER - must find and unmask a double agent.

CIA headquarters in Langley receive a cryptic message from an agent operating deep undercover in Russia: 'He has betrayed us and wants to go to war.' Unable to make contact, the Director of Operations is forced to turn to one of his most deadly field officers - Will Cochrane. His mission: infiltrate the remote submarine base in eastern Russia's Avacha Bay and decode the message - or die trying.

It's a near-impossible task. When Will locates the base, the undercover agent is dying, his final words are, 'Only Sentinel can stop him.' With tensions between the two superpowers building, it's up to Will to uncover the true meaning of the dying man's words - and discover the identity of the legendary operative known only as 'Sentinel.'
