Surely a peaceful holiday in the Welsh mountains will keep the children out of trouble! But the mystery of a rumbling mountain soon has them thirsty for more adventure.
Philip, Dinah, Lucy-Ann and Jack are determined to explore the mountain and uncover its secret, but first they must escape from a pack of ravenous wolves and a mad genius who plans to rule the world!
