Cadfael (TV series 1994-1996)

At and around the Shewsberry abbey, Brother Cadfael is a monk with a difference. Given a choice, he would enjoy just being a simple gardener and herbalist for his home. However too often, events force him to use his other talent as a master sleuth in response to mysterious crimes happening in his community. While he investigates these crimes, he often finds himself at odds with the contemporary attitudes of the times with his own ahead of his time beliefs. - IMDb
