Little Mary Lennox is a bad-tempered, disagreeable child. When her parents die in India, she is sent back to England to live with her uncle in a big, lonely, old house. There is nothing to do all day except walk in the gardens - and watch the robin flying over the high walls of the secret garden... which has been locked for ten years. And no one has the key.
