The friendly Mr. Knorps arrives and does his best to solve the problem - but suddenly the refrigerator heats up, an ice layer forms in the oven, and the light goes out when you pick up the phone receiver. From then on, Mr. Knorps comes every day, and the apartment becomes cozier and cozier! Bilingual Arabic-German edition.
