The Wycliffe series had a good cast, it is entertaining. The production quality is quite high. I hope they continue to release all the series - I believe there are 5 series, and also the pilot movie, and the special. If you like British (specifically Cornwall) mysteries, these are great. They are slightly dated by some of the technology but not too bad. My only gripe is that it doesn't have captioning - sometimes the British slang needs to be interpreted, but I have trouble figuring out exactly what they did say.
The episodes in Series Three are: Dead on Arrival, Number of the Beast, Slave of Duty, Total Loss, Crazy for You, Faith, Last Judgement, and Old Habits.
