I have to disagree with the other reviewers, and stand up for a Midsummer Nightmare, it's true the quality of the series had dipped by this point, but this episode has some real quality. The story is excellent, it's clever and well thought out, the Shakespeare theme was great. Red herrings galore, exactly what you want from a decent thriller. Jody makes a great lead character, she's interesting, and her side story with Johnny is great. Almost every single character is suspected, from the housekeeper to the Uncle.
A great cast, Brian Blessed, Freddie Jones and Norman Rodway are all great, but it is Joanna Pettet who impresses most.
The penultimate episode is a very good one, 9/10
