Agatha Christie: Twelve Radio Mysteries: Twelve BBC Radio 4 Dramatisations - Full Cast, Tom Hollander, Julia McKenzie, Agatha Christie,  Emilia Fox
This is really good.
I listened to 3 more stories last night...way beyond my bedtime...and the only one that was a little underwhelming was Witness for the Prosecution. I'm sure knowing the play already had something to do with it but I didn't feel it had the same clarity or doom as the other ones.
I really want to look up Christie's original stories/plays that the 12 productions are based on, especially Swan Song and Philomel Cottage so far.
