Tilly's moonlight fox

'The fox called again. Its eerie cry echoed into the night. The sound wove in and out of the night garden, and into Tilly's dreams.' One night, awoken by a strange noise, Tilly looks out of her bedroom window and sees a wild fox watching her from the lawn. Tilly follows it through a hidden gate and is amazed to discover a secret, moonlit garden. She returns the following night but this time a young girl called Helen is already there waiting for her. Tilly is delighted to have found a new friend, but is Helen real or is she a ghost?
