These BBC Radio adaptations of Agatha Christie's Hercule Poirot mystery series are well-suited for occasions when you'd like to listen to something short and engaging in full - bedtime, doing a bit of housework, running errands, commuting, or sitting in a waiting room. This is one of my favourites so far because of the particular method of questioning that Poirot puts to the potential murder suspects. And the cast is quite good, including John Moffatt as Poirot.
I listened to this one several times using my iPad and the Libby app from Overdrive Libraries - my valued go-to source of audiobooks courtesy of my local library system.
