Children's literature R. M. Ballantyne and G. A. Henty specializing in the production of adventure fiction for boys. This inspired writers who normally catered to adult audiences to write for children, and an example is Robert Louis Stevenson's (1850–94) classic pirate story "Treasure Island" (1883). In the years after the First World War, writers such as Arthur Ransome (1884–1967) developed the adventure genre by setting the adventure in Britain rather than distant countries. Ransome began publishing in 1930 his Swallows and Amazons series of children's books about the school-holiday adventures of children, mostly in the English Lake District and the Norfolk Broads.
Swallows and Amazons by Catherine Poole, Peggy by Jackie Swainson and Uncle Jim by Nicholas Le Prevost. The Royal National Theatre started developing a musical version of "Swallows and Amazons" in 2007. Helen Edmundson wrote the book and lyrics while The Divine Comedy's frontman Neil Hannon wrote the music. The musical premiered at the Bristol Old Vic on 1 December 2010 and played at the Vaudeville Theatre, in London's West End, from 15 December 2011, prior to going on tour around the UK from January to May 2012. The production features adults playing the children and has been received favourably by reviewers. Swallows
