Eyes sparkling and tweeds impeccable, Julia McKenzie (Cranford, Notes on a Scandal) returns as Agatha Christie's spinster sleuth in three new mysteries set in 1950s England. Murder is afoot, and Miss Marple is up to the task of determining whodunit. She may look like a pensioner, but she doesn't miss a clue on the way to solving heinous crimes, whether the weapon is a gun, a cocktail, or the color blue. Each story unfolds against a rich background of grand English estates, gorgeous scenery, and post-WWII period detail. Julia McKenzie proves "delightful to watch" (Los Angeles Times), and she's supported by a stellar cast of veteran British actors including Lindsay Duncan, Joanna Lumley, Hugh Bonneville, Edward Fox, Caroline Quentin, Jonas Armstrong, Sharon Small, Kevin McNally, and Toby Stephens. 3 or 4 episodes; approx. 267 min., plus 66 minutes of bonus programming. 4 DVD or Blu-ray discs.
