Kate Summerscale’s latest book, The Haunting of Alma Fielding, is a gripping narrative that follows the investigation of supernatural experiences in the shadow of war, and the unraveling of a story of trauma, loss and alienation. Summerscale is  also the author of  bestsellers The Suspicions of Mr Whicher and The Queen of Whale Cay. In conversation with historian and author Ira Mukhoty, Summerscale explores the 1930s case of the ‘Croydon Poltergeist’ and the hidden folds of the human mind.
