It all starts with Paavo's tall tales. He is the new kid in school and actually quite nice. But he wants to be the best at everything, and his father is supposedly the most famous film director in the world. If the others don't believe him, they just need to come along on Saturday when he visits him in the city. But suddenly, Paavo disappears. Does he want the others to look for him? They might as well give it a try. Ella and her friends embark on a treasure hunt and create a huge mess. The seventh Ella book by the bestselling author from Finland - for everyone who loves to laugh until they cry while reading (or being read to).
