Outside o the two Miss Marple collection sets are three videos that are more of a made for television series. This is one "A Pocketful of Rye"
Rex Fortescue (Timothy West) is out of character as he arrives at is office. You immediately know something is wrong because this is England and Rex has ordered his tea much too early. Yep mean old nasty Rex is found later dead. Thorough detectives have determined that there was some mysterious grain in his pocket. If you remember the nursery rime you can follow the story.
So how does Jane become involved? She trained the maid and is afraid for her safety. If you remember the maid was also in the nursery rime along with several of the other characters.
Naturally at several places in the mystery Miss Marple (Joan Hickson) points out the obvious to Det. Sergeant Hay (Jon Glover) who realizes and corrects the error of not listening to her.
As with most Miss Marple stories several people make the most obvious suspects in foul play. And as in many of her stories the most obvious tends to be the next victim.
Aside from the story you will notice that as with most Joan Hicks/Marple movies many of the actors are major English actors and can be seen in other movies and TV series.
There is only one repugnant scene where you have to watch Rex eat. Other than that it is a thoroughly enjoyable mystery.
