This story starts in 2012. Oliver is a dashing young diplomat, working in Afghanistan. Charlie is a graduate newly arrived in London, trying to find her feet in the world. The pair meet online and she falls in love. But only a few months later, she discovers that the story Oliver has told her about his life is not what it seems. 

A decade later, this man has climbed to the top of academia, the civil service, and into the world of national security, eventually founding a billion-dollar company selling AI to the military. 

But a mystery hangs over Charlie: did the untruths continue, and if they did, why haven’t caught up with him?
