What if the CIA and British intelligence began spying on each other? This is the question at the heart of David McCloskey's thrilling fifth novel. A new US Administration has taken office, installing a brash and unconventional CIA Director determined to disrupt the Agency and sceptical of its close relationship with their cousins across the Atlantic. Case officers, including newly installed London Chief of Station, Artemis Procter, must now navigate a tense environment as old friends become adversaries and no one knows who to trust. When agents run by both services begin dying, Procter and her team at London Station must decide whether loyalty to the Mission and their friends means disobeying the Agency they serve.

Immersing readers in the technological revolution upending intelligence tradecraft, David McCloskey's brilliant new thriller depicts the nuts-and-bolts mechanics of how CIA and MI6 collaborate and explores what happens when politics threaten to destroy the 'Special Relationship' between America and Britain.
