Wonderful Joan Hickson I have never thought that Margaret Rutherford was the perfect actress to portray Christie's famous lady detective.Angela Landsbury,who portrayed her in "the mirror cracked" was not an ideal choice either.Joan Hickson was Miss Marple as I see her ,discreet ,insightful,mischievous,terribly observant.She and the detective inspector make a funny pair,like Poirot and Japp. Unlike Poirot,Marple does not really investigate.She never questions the suspects (some of whom even use her as their alibi)but has a rare talent for observation.
