With a gentle smile and a probing mind, Agatha Christie's Miss Marple often finds herself at the center of trouble — a witness to betrayals, poisonings and all manner of mayhem. Knitting needles in hand and a cup of tea always at the ready, Marple quietly earns confidence while uncovering secrets and exposing killers.

In Series V, premiering in the summer of 2010 on Masterpiece Mystery!, Miss Marple tackles three tough new cases — The Mirror Crack'd from Side to Side (May 23), The Secret of Chimneys (June 20) and The Blue Geranium (June 27). In the new episodes, McKenzie is supported by a lineup of top-notch acting talent. They include Joanna Lumley (Absolutely Fabulous), Lindsay Duncan (Alice in Wonderland), Stephen Dillane (God on Trial), Sharon Small (The Inspector Lynley Mysteries) and Toby Stephens (Jane Eyre) among others.
