An incident has occurred! Opera City has become a chaotic maze!
A high-quality maze and hidden picture series for young detectives with a talent for mystery.

One day, a letter arrives at Pierre's detective agency, where he solves cases by solving mazes and finding his way through them.
The unidentified villain X stole the maze stone from the museum.
This theft turns Opera City into a maze of chaos.
Can labyrinth detective Pierre recover the stolen labyrinth stone and save Opera City from peril? Join detective Pierre and his assistant and friend, Carmen, on their adventure.

From a museum with lost labyrinth stones to a bustling city festival, an exciting shopping street selling various goods, a hot air balloon festival flying through a sky maze, the eerie Dracula's mansion, the sea, a mine, and a strange flea market underground, you will search through 15 unique locations, each transformed into a maze, and chase after the villain X.

How to read this book with enjoyment
Here's a fun way to follow the structure of this fascinating book:


▶First, read the first chapter, ‘How to Enjoy This Book,’ carefully to figure out how to enjoy the activities.
▶Look at the picture as a whole and find the departure sign with Pierre and the arrival sign next to the villain X.
▶Read the story about the place carefully and set out to find clues to solve the maze.
▶After solving the maze, you can look at the picture in detail and solve the items lost by the residents, quizzes in newspaper articles, and even the challenges of Villain X.
▶ After completing the maze and hidden picture puzzle, you can move on to the next chapter.


After completing all the adventures, the answers to the activities in the text are included in the last chapter, so even children who struggle with the mazes or haven't found all the hidden pictures can solve the problems again.
Additionally, bonus problems and trivia quizzes are hidden on every page, allowing you to enjoy solving new problems.
This book helps develop the brain by helping children figure out what objects they need to find while reading and by examining each detailed picture one by one using concentration and cognitive skills.


It's worth collecting because of its detailed illustrations that are fun to look at in every nook and cranny!
The large format allows you to find not only mazes but also hidden treasures and items throughout the game!

IC4 Design, an illustration group that has won numerous design and advertising awards including the Cannes Lions International Festival of Creativity, the ADC Awards, the D&AD Awards, and the NYX Awards, said that the direction of the group was determined by a single word from the chief art director when working on the cover of the New York Times: “I want illustrations that can be looked at for five minutes, not five seconds.”
This picture book took three years to create, from idea to sketch to publication, to achieve such delicate and rich illustrations.

Pierre's adventure begins after an introduction that introduces the characters and how to read the book, as if starting a game, and a cover featuring typography from the 1920s and 1930s, which is the era in which Pierre embarks on his adventure.
This picture book combines maze and search elements with a chase story, and the overall content is an intuitive structure of chasing the villain X.
But the new locations that unfold with each turn of the page provide the pleasure of being sucked into a new adventure each time.
Children who read the book can develop their observation and spatial perception skills by guessing which path to take to chase down Villain X.
Publisher's Weekly commented, "Pierre's adventures, reminiscent of Sherlock Holmes, combine detailed illustrations and storytelling on par with the international bestselling Where's Waldo? series, a delight for discerning readers."


Another fun element is taking a look back at the people, cafes, and other buildings in the city that you missed while solving the problem.
This picture book is a feast for the eyes, with over 100 hot air balloons of various sizes and shapes in the hot air balloon festival, people resting and enjoying themselves in the cafe, various animals of various shapes and colors, and even small, simple mazes hidden throughout.
