Auntie Poldi and the Fruits of the Lord

Auntie Poldi is annoyed: first they shut off her water then someone offs her friend's dog. For crying out loud! Her investigations take her to the wine-grower Avola. Unfortunately he is not only a suspect but also an extremely attractive guy - and after a hot night with him Poldi discontinues her investigations. Instead the following morning the police show up at Avola's door. Between his vines they found the dead body of a fortune-teller Madame Sahara. Commissario Montana is anything but pleased that Poldi can provide Avola with an alibi. Moreover the question remains: who killed the fortune-teller - and why?
