This is the box set DVD for season 5 of the Miss Marple remake made in 2004-2013 (in IMDB you can find this series of remade movies as Marple (2004-2013)). The lead in season 5 was Julia McKenzie. There are 4 movies in this season; The Pale Horse, The Secret of Chimneys, The Blue Geranium and The Mirror Crack’d from Side to Side.
The two linked films are both wrong (wrong title and wrong lead), these are earlier versions from the 80s and 90s.
