I have long been a fan of this series. Hetty is a more modern Miss Marple. She uses her ordinariness to solve crimes. No one suspects the charming senior housewife. Several years after seeing this episode, I was reading a novel by Nicolas Frieling. Of course his detective is male and lives in Holland. So as I read my way through his novel Double-Barrel, I realize that the plot seemed terribly familiar. Someone in a remote area of Holland is writing poison pen letter's which are having a rather disastrous effect upon a small community. Our hero is assigned to discover who is writing these and put an end to it. He goes undercover. If you have seen this episode of Hetty, You will realize that it is the same as the Freeling novel. I think Freeling did it better but I have found no record of him getting credit for the Hetty episode.
