Quarantined in his aunt's and uncle's stuffy flat, ten-year-old Tom is restless and bored. Intrigued by a grandfather clock, Tom is startled one night to hear it strike 13! Slipping out of bed he discovers a beautiful 1880s Victorian garden, which before was just a small back yard. In the garden he meets unhappy orphan, Hatty. A special friendship develops between Tom and Hatty as they share fun and adventures together in the magical garden. Philippa Pearce's 1950s classic is brilliantly adapted for the stage by David Wood.
