Have always been quite fond of 'Murder She Wrote'. It is a fun and relaxing watch that makes you think as you try to unwind in the evening. If one wants more complex, twisty mysteries with lots of tension and suspense 'Murder She Wrote' may not be for you, but if you want something light-hearted and entertaining but still provide good mysteries 'Murder She Wrote' fits the bill just fine.
While there are better Season 4 episodes, such as "Witness for the Defense", "Old Habits Die Hard", "Trouble in Eden" and "Mourning Among the Wisterias", "Benedict Arnold Slipped Here" is still good fun, more than it had the right to be somewhat considering the fairly nasty premise. It doesn't have anything wrong with it as such, just that it doesn't quite have the spark of the best 'Murder She Wrote' episodes.
The mystery is entertaining and intriguing, with some interesting history even. It is also nowhere near as lacking-in-taste as it sounds even with the nasty heir characters. There are nice surprises, it's never confusing and it's not too much of an easy mystery to solve either.
Angela Lansbury as usual is terrific, as are the always dependable William Windom and Tom Bosley. Brian Bedford and David Clennon fare the best of the supporting cast, very strong performances.
It is the supporting acting in "Benedict Arnold Slipped Here" that is the episode's least good component. Certainly not awful, just uninspired.
Production values are slick and stylish as ever with 'Murder She Wrote'. The music has energy and has presence but also not making the mistake of over-scoring, while it is hard to forget or resist the theme tune.
Writing is thought-provoking, light-hearted and amiable.
Overall, fun and interesting episode. 8/10 Bethany Cox
