Where is Mimi? Kim, Franzi, and Marie meet their friends Nele and Juri at Café Pfote. The two have come here for different reasons. Nele particularly likes the cat Mimi because she reminds her of her tomcat Moppel, who has disappeared without a trace. Juri's parents do not want to have a pet. When the three return to the café the next day, there is great excitement: Mimi is gone. Juri is acting strangely. The three find themselves in a new case and receive support for it. An interactive book for learning to read, featuring simple print, four-color illustrations, and a riddle after each chapter.
