When both the school bus and Sarah Jane's car break down in Snowdonia en route to their campsite, the gang find themselves stranded in the middle of nowhere. Exploring by a lake, Rani sees a shadowy figure that looks exactly like her. Then Sarah Jane hears a voice asking for help, and sees a mysterious figure outside her tent. Who is watching them, and why? How can Rani be in two places at once? And what secret does a nearby cave hold? Elisabeth Sladen, who stars as Sarah Jane in the CBBC TV series, reads this exclusive audio story by Scott Handcock.
