Agatha Crispy is traveling around the world! But at every stop, strange things happen! Thefts, disappearances, kidnappings: a multitude of cases await her... With your help, she will manage to solve all the puzzles! Eight funny cases that require observation and critical thinking. A series of activity books where the child is invited each time to solve 8 mysteries, each set in a different environment, e.g., at the station, at school, at the bank, in the lab, at the circus, in the museum, etc. The mysteries are independent, but each book has a common theme and always the same heroine, Agatha Crispy. To solve the mysteries, the child must look for details in the picture and answer questions using logic, observation, and critical thinking.
