A young man is invited to dinner by his best friend and his wife (with whom he's secretly in love). The other guests include the man's uncle, a respected psychiatrist, an outgoing lady (Carol Drinkwater, in a fun performance), and the icing on the cake, a female medium who will hold a seance in the house. Just as he's getting dressed, our hero receives "the red signal" - a sort of premonition that warns him that something bad is about to happen. And later in the night, the medium agrees...."The Red Signal" is probably the most traditionally Agatha Christie-ian episode of this series: a tricky whodunit (but also for a while a who-will-it-be-done-to), with a hint of the supernatural, which counts on the viewer's misinterpretation - in a crucial scene, you think you're seeing one thing, but in fact you're seeing another. Gripping story and intelligent dialogue (about the nature of madness and the power of the subconscious) make this one of the best episodes in the series. *** out of 4.
