John presents her novel The Haunting of Henry Twist – a mysterious love story set in 1926 that recalls the power and strangeness of Stevenson’s Dr Jekyll and Mr Hyde. Arnott’s The Fatal Tree is set 200 years earlier and is about the true story of Edgeworth Bess, which mesmerised C18th society: a riveting, artful tale of crime and rough justice, love and betrayal. Rich in the street slang of the era, it vividly conjures up a murky world of illicit dens and molly-houses; a world where life was lived on the edge, in the shadow of that fatal tree – the gallows.
