Mark Gatiss steps into the mind of M.R. James, the enigmatic English master of the supernatural story. How did this donnish Victorian bachelor, conservative by nature and a devout Anglican, come to create tales that continue to chill readers more than a century on? Mark attempts to uncover the secrets of James's inspiration, taking an atmospheric journey from James's childhood home in Suffolk to Eton, Cambridge and France, venturing into ancient churches, dark cloisters and echoing libraries along the way.

Robert Lloyd Parry visits Felixstowe in search of the inspirations for M.R. James' ghost story Oh, Whistle and I'll Come to You My Lad.
