The 4 friends and Daisy the dog investigating at the school theatre.
The rehearsals for the school play are chaotic, to put it mildly. The main characters keep forgetting their lines, and Daisy tries to out-bark the musical instruments. So nobody except the 4 ½ friends notices that the play director keeps getting suspicious phone calls. When Friedhelm then goes and finds a blackmail letter, it is a clear-cut case for the 4 ½ friends: they will have to shadow the director.
