On 14 June 2006, the elderly writer Allan Chappelow was found buried under his own manuscripts at number 9 Downshire Hill in Hampstead. Who killed him? Why was the trial held in secret? What is the truth? The explosive new book from Hanns and Rudolf author Thomas Harding tells an extraordinary tale of isolation, deception, espionage and brutal violence, stretching from the quiet streets of North London to the Palace of Westminster and beyond. Thomas Harding will be in conversation with journalist and author Duncan Campbell.
