Most background to this series will be found in my review here for the first in this grouping of four television dramas, 4.50 from Paddington.
All we need to say here is that if you enjoyed the first, you'll want this one. It fleshes out quite a bit more of the character of Miss Marple, here played by Geraldine McEwan in the absolute best film dramatisation yet of Agatha Christie's famous spinster-heroine.
The victim here is village-bigshot Colonel Prothero, played by Derek (I Claudius) Jacobi. Prothero has his finger in every village-pie, and is universally detested. About the only person in the drama without a motive for his murder is the butler. Does that mean that this time the butler dunnit?
This is a beautiful realisation of an Agatha Christie novel, with skillful adaptation of the original story to make it more appealing to a wider general audience than the original mysteries reached. And if you think Joan Hickson did a good job as Marple -- well, you ain't seen nothing yet.
The transfer is anamorphic, and is of reasonably good, though not outstanding, quality. It's certainly sound enough to make this pleasant viewing, and the stereo sound is impressively detailed.
There are no extras of any sort. The Region One extras accompanying their Miss Marple box are detailed in my review of 4.50 from Paddington.
