BEFORE her death in 1976, Queen of Crime Agatha Christie described Joan Hickson as the ideal actress to play her ageing supersleuth Miss Marple.
That's a pretty good recommendation for tonight's final BBC Week offering, a Christie mystery which stars the said Ms Hickson as the said very private detective.
Agatha Christie's Miss Marple: They Do It With Mirrors (Pearl, 9.45pm, Original Running Time 111 minutes) revolves around a murder at a country mansion. The problem is Miss Marple knows whodunit, but not how they dunit.
Miss Marple is summoned to Stonygates mansion by a friend worried about the health of her sister Carrie-Louise Serrocold, played by veteran Hollywood actress Jean Simmons (Guys and Dolls).
Our intrepid spinster finds the sister in perfect health, and she's more concerned about the obvious trouble brewing among other members of the feuding family.
Husband Lewis Serrocold (Joss Ackland) is a social reformer who's making powerful enemies, and the woman's daughter and grand-daughter are constantly fighting among themselves - when they're not dosing granny up .
WORLD'S alternative is a disaster movie in more ways than one. The Concorde - Airport '79 (9.30pm, ORT 123 mins) is the last in the Alex Hailey-inspired quartet of air crash movies.
