Cracking adventures on the island of Castle Key are at the heart of this exciting series. Jack and his brother Scott are sure their holiday in this remote location in Cornwall will be dull. But, how wrong can they be? Jack and Scott team up with Emily and her bouncy dog Drift whose home is in a converted light house and soon find the Island is full of surprises and excitement. First there’s the mystery of why the caves have lost their whistle (in The Mystery of the Whistling Caves), then there’s the shock of a film star going missing (in The Mystery of the Midnight Ghost) and finally there a man who almost drowns on the beach (in The Mystery of the Drowning Man). Can the friends pull him from the water in time and can they find out who he is? With its crumbling cliffs, pounding seas and interesting cast of inhabitants, Castle Key turns out to be a wonderful place for a holiday.
