Sarah Wise is the author of four works exploring occluded aspects of life in Britain. Her debut, The Italian Boy re-examined a serial killing spree in Regency London. Subsequent ‘dark’ histories include life in the East End’s poorest slum; and the Mental Deficiency Act, 1913 – stories of lives often missing from history books. misssarahwise.co.uk and www.sarahwise.co.uk
