John Bunyan in Bedfordshire. The novelist Rachel Joyce joins Henry as they follow in the footsteps of Bunyan’s pilgrim Christian, as he walks from Bedford, or the City of Destruction, to London, the Celestial City. Along the way they visit the Slough of Despond (Elstow), the Palace Beautiful (Houghton House) and Vanity Fair (Ampthill). They start at the Bunyan Meeting House, where they meet John Pestell, and finish at Bunyan’s resting place, Bunhill Fields.
