In this, the third Ian and Sovra story, the pair discover that life in Edinburgh can be as thrilling as life in their own Western Highlands. For there they meet Cathie, who's escaped from an orphanage. They smuggle her out to a secret hut on the coast, where, after her rides in lorries and rolls of carpet, she's only too delighted to enjoy the free outdoor life of her new friends, while Ian and Sovra do a spot of detection for her. How they solved the mystery and found that this land of mountains, lochs and white sand really was Cathie's home is told in this exciting new adventure.
