It’s time for a marvellous mini adventure with secret agents Miss Sophie Taylor and Miss Lillian Rose!

Sophie and Lil are on their very first case for the Secret Service Bureau in this thrilling adventure. They travel to the seaside town of Rye where – despite its sleepy appearance – they have evidence that a band of German spies are plotting dastardly deeds. Can our two brave detectives navigate smugglers tunnels, make it through treacherous sea mists and decode a secret message to solve the mystery?
