La ladra di lettere. L’alfabeto che scompare

Margherita is a teacher in a school where, during class, the letter ‘H’ disappears from the alphabet, from all the books, from every word! It is a mistery, and without the H also questions disappear: ‘How are you doing?’ ‘How many pizzas are we going to eat?’ After words, also numbers start disappearing. So 3 rolls over 6 as it doesn’t have the help of 4 and 5 anymore. Margherita can’t sit idle: she needs to find out who is the thief of letters. To solve the mistery she needs the help of a squad of special detectives: Nonna, Luly (the girl with strong pigtails), her dog Seby and the letter enchanter.
