This is an automatically translated description

The headmaster of the School of Magical Animals has his favourite slippers stolen. The shadow of suspicion falls on the students... And only Detective Murphy, the polar bear, can expose the thief. The child will be so immersed in the search for the missing slippers that he or she will not even notice how the last page is turned. A crossword puzzle at the end of the book will help you find out how attentive the little reader (and detective!) was. And to make reading even easier and more interesting, the syllables in difficult words have different colours.
