Not one of us must breathe a word of what we've found. It's a dark and stormy night. Jim, the inn-keeper's granddaughter, opens the door to a terrifying stranger. At the old sailor's feet sits a huge sea-chest, full of secrets. Jim invites him in - and her dangerous voyage begins. Treasure Island, Robert Louis Stevenson's classic story of murder, money and mutiny, premiered at the National Theatre, London, in December 2014, in a thrilling adaptation by Bryony Lavery.
