Downton Abbey star Phyllis Logan was joined by her real-life husband, Kevin McNally, in the latest episode of 5's new crime drama, Murder Most Puzzling.
Based on author Parnell Hall's best-selling series, The Puzzle Lady Mysteries, the drama follows Cora Felton, the eponymous Puzzle Lady, whose talent for crossword-solving is unexpectedly called upon by the local police of a quiet town.
Kevin, known for his roles in the Pirates of the Caribbean franchise, The Crown and Unforgotten, plays Cora's potential love interest, Gilbert. According to the episode synopsis, "Cora is distracted by love, as she's wooed by a charming suitor, Gilbert. When Sherry says he seems too good to be true, it causes a rift between the women but plants a seed of doubt in Cora's mind."
