Poirot

5.55PM, ITV3

David Suchet’s Poirot investigates The ABC Murders, the case that John Malkovich’s Poirot is looking into at 9pm on BBC1. Here, the Belgian is joined by the cheerily idiotic Hastings (Hugh Fraser, near left, with Suchet) as they arrive at a murder scene where the killer has left them a single clue: an ABC Railway Guide.
