Agatha Christie. Murder with mirrors. [videorecording (DVD)]

Marple has been summoned to the lavish country estate of her old friend Carrie Louise Serrocold (Bette Davis). Carrie's stepson has been killed, and she fears that his won't be the last corpse to befoul the estate. She's right, and the game is afoot for Miss Marple once more, with a full contingent of prime suspects (including John Mills, Leo McKern and Dorothy Tutin). Murder with Mirrors was filmed on location on a genuine 13th century British estate. If Helen Hayes seems more spirited than Bette Davis (eight years Helen's junior), it's because Bette was seriously ill prior to and during shooting.
