I listened to this one BBC Radio 4. If you'd like to listen to it, it still has three weeks and can be found here.
I could swear I have listened to something like this before but I can't remember who did it or when it was. This version was quite good, a full cast brought the scenes to life and John Moffatt does a very passable Hercule Poirot. I'll admit, I'm partial to David Suchet but I quite like this version of the great detective.
The mystery, which I remembered partially but not enough to be sure who did it, was very good and, which short, ranks high in Poirot's mysteries for me.
Audible seems to have several of these available...I think my wish list on there is going to grow.
