Jumbo East Frisian melody

Rupert and the Annoying Mother-in-Law. It was one of those afternoons with strawberry cake and whipped cream, a wonderfully blue sky, and a gentle breeze that couldn't have been more perfect. If it hadn't been for Rupert's annoying mother-in-law, who had invited herself over for coffee. The commotion was quickly explained: out of the blue, a seagull had dropped something that definitely did not belong on Rupert's windshield - a human finger. And Rupert's neighbor, an irritating music teacher, had left the porch door open for quite some time. As Rupert approached the house, he sensed trouble. And indeed, the teacher lay dead next to the piano. A case for Super-Commissioner Rupert and his mother-in-law, who just won't be shaken off.
