This is probably the most densely plotted of the three Margaret Rutherford Marple films I've seen so far - it is based on a Hercule Poirot story ("Mrs. McGinty's Dead") which has already been adapted for the screen as part of the David Suchet series, but although I have seen that film, I did not remember much of it beyond the initial setup, so I was caught up in the various murders and red herrings that follow. I also think this might be Rutherford's top performance as Marple - she has some great facial expressions (like when she's teasing Mr. Stringer), some great lines ("A Marple's word is her bond!"), some great tricks (a small mirror attached to an umbrella!), and at the end she even gets to fire a gun - something that would be unthinkable for any other actress who ever played this character, but fits perfectly with her portrayal! The supporting cast is also strong in this one. The only problem with the film is the same with the previous entries: occasionally it moves like molasses. *** out of 4.
