By the Pricking of My Thumbs

S2 E3: Something wicked this way comes to Sunny Ridge Retirement Home for Ladies. Miss Marple's teams up with detective duo Tommy and Tuppence to investigate the suspicious death of Tommy's Aunt Ada and sudden disappearance of Ada's friend Mrs. Lancaster, both residents of Sunny Ridge. An oddly doctored painting and tantalizing crossword clues lead Tuppence and Miss Marple to Farrell St. Edmund, a village that seems straight out of a fairy tale-complete with lurking evil.
