While spending a holiday at Bertram's hotel in London, a hotel that caters to those who prefer the Edwardian formality of a past era, Miss Marple (Joan Hickson) can't help but feel that something is wrong with the surroundings. Everything looks and feels authentic but there's an atmosphere of falsity that encompasses the milieu. When an absent minded clergyman (Preston Lockwood) disappears, the hotel's dark secret begins to unravel. Not one of Agatha Christie's best late works but for the most part, there are enough twists and turns to keep the viewer engrossed in the proceedings. Hickson is, of course, the definitive Miss Marple to anyone who has read the Christie's Marple mysteries. The ending is a bit of a letdown though with a rather silly chase that would have had Christie cringing. Directed by Mary McMurray and with Joan Greenwood, whose beauty has faded but there's no mistaking that plum voice of hers, George Baker and Caroline Blakiston as an aging, international playgirl whose past is a key to solving the mystery.
