They are holy men. But they are ambitious. And they have rivals.

Over the next 72 hours, one of them will become the most powerful spiritual figure on earth. Who will it be?

That is, until family friend Chris comes to stay.

He’s been on the path to uncover a sinister think-tank, founded at Cambridge University in the 1980s, that’s been scheming to push the British government in a more extreme direction. One that’s finally poised to put their plans into action.

But speaking truth to power can be dangerous – and power will stop at nothing to stay on top.

As Britain finds itself under the leadership of a new Prime Minister whose tenure will only last for seven weeks, Chris pursues his story to a conference being held deep in the Cotswolds, where events take a sinister turn and a murder enquiry is soon in progress. But will the solution to the mystery lie in contemporary politics, or in a literary enigma that is almost forty years old?

Darting between decades and genres, THE PROOF OF MY INNOCENCE is a wickedly funny and razor-sharp new novel from one of Britain’s most beloved novelists, showing how the key to understanding the present can often be found in the murkiest corners of the past.
