Orphaned Mary Lennox is sent to live at her uncle's gloomy house on the Yorkshire moors. Wandering the grounds, befriended only by a robin, she finds a key - the key to a garden her uncle locked away ten years before. This is not the only discovery Mary is to make at the Manor. She meets Dickon, the boy who can charm wild animals. And there is a strange crying in the night that only she seems able to hear . . .
