The Missing Harmonica
Findus is bored. To put him in a good mood, Pettson entrusts him with his old harmonica, which the little cat is allowed to play for a change. Findus promises to take the best possible care of it and immediately starts playing with the valuable heirloom outside in the yard until he takes a little break. Shortly afterwards the harmonica has disappeared. Does Beda Andersson's cow have anything to do with it?
