Pierre the Maze Detective has a new case! Mr X has stolen the Maze Stone — a powerful artifact with the ability to turn all of Opera City into a maze. Join Pierre and his friend Carmen as they race through underground cities, hot-air balloon adventures, tree-top towns, and haunted houses, hunting for clues to crack the case before it's too late. Every page is a richly illustrated puzzle waiting to be solved, and a full solutions section at the back means no one gets left behind.
