Lord Edgware Dies

S7, E2: When Lord Edgware mysteriously dies there is a long list of shifty-looking suspects - including the butler. Poirot has his work cut out to unmask the murderer. Lord Edgware was a brute and hated by many, including his beautiful actress wife Jane. She claims she visited him on the night of his murder, but witnesses place her somewhere else at the same time. How could this be? Unearthing the killer is harder, not least because Poirot's 'leetle grey cells' are focused on the woman and not the crime.
