Max and Sally expect a camping trip, but a gang of crooks searching for smugglers' treasure changes their plans. Clues take the pair from the shore towards a house on the cliff, with secret passages and traps along the way. Readers solve illustrated puzzles to help them uncover the treasure before the crooks do.
