From Net Flix:

“Detective Chief Inspector Tom Barnaby (John Nettles) can’t
help but notice that more people than ever before seem
interested in the work of long-dead composer Joan Alder,
who wrote the well-known song ‘Midsomer Rhapsody.’ First,
Alder’s former music teacher turns up dead, and an early
draft of her most famous piece is found among his
possessions. But the plot thickens when Alder’s
long-lost daughter, Sarah, comes back into town.

Thanks to Nora for suggesting this series. Unfortunately for Kathy and for
me there are no subtitles. We have trouble understanding the male actors.
NetFlix claims to have 300 different Midsomer Murders. I stopped counting
at 30 installments. Kathy and I prefer the “Touch of Frost” series if only
because it offers subtitles.
