Compare this to _They Do It with Mirrors (1991) (TV)_ and you see why even Agatha Christie thought 'Joan Hickson' (qv) the perfect Miss Marple. Not even Sir 'John Mills' (qv), 'Bette Davis' (qv) and 'Helen Hayes' (qv) can make this film truly enjoyable. The producers must have been unable to afford to set the film in its time, and just dropped it 40 or 50 years out-of-time: doomed from the start.
