I can't help you with that! I much preferred the old episodes, with Barnaby and his wife, rather than the newer ones featuring his nephew!!! Have you noticed that there are TWO murders in almost EVERY episode? Soon Midsomer will have no citizens left!!!
My husband I have had the same thought -- they're going to run out of citizens! Just caught the last episode of Dr. Blake's Murder Mysteries and discovered it was the series finale. No more Dr. Blake. DH and I really enjoyed this series and are sorry to see it ending.
