Until he puts it on and discovers its magic properties. Suddenly our hero becomes a spy, under surveillance by a mysterious other. In order to lose his tail, he travels to an oasis, the desert and even crosses the ocean in a boat. That's when his mother calls him to go to bed. But he's not upset: He can keep reading his favorite book of adventure stories, and decides after all that his grandfather's old hat might be ugly, but he likes it. A love letter to the imagination with which the reader shares in the adventures and identifies with the child narrator.
