The Cosgood Players are knocking 'em dead. Literally. No matter what's on the playbill, the shabby repertory company seems to specialize in mysteries as members of the troupe shuffle off this mortal coil in alarmingly rapid succession. Luckily, the Players have a detective in the cast: their newest (if not quite an ingenue) thespian, the redoubtable Miss Marple. Margaret Rutherford takes her final bow as Miss Marple in Murder Most Foul, a mystery most fun inspired by Agatha Christie's Mrs. McGinty's Dead. Ron Moody (Oliver!) costars in an ingenious baffler abounding in suspects, clues and red herrings -- all ending in the unmasking of the murderer during a performance. Curtain up!
