Montalbano goes to The Potter's Field

The penultimate episode in this second run of Inspector Montalbano, at 9pm on 3 November, is The Potter's Field, based on The Potter's Field book, the thirteenth in Camilleri's series. The Potter's Field (which I loved) is arguably a perfect crime novel and won the 2012 CWA International Dagger.

As torrential rain pours down on Vigata, a plastic bag containing a body cut into pieces is found in a clay field. All the signs point to an old-fashioned Mafia killing. But why is Montalbano's trusted colleague and friend Mimi Augello suddenly irritable and short-tempered, and why is he insisting that the investigation be assigned to him? Could Mimi somehow be involved in the case?
