A specific grouping, but I know there's at least four...
Someone has been uploading German adaptations of the Wimsey short stories to YouTube - I assume they are radio productions. There's
The Undignified Melodrama of the Bone of Contention,
The Man Without a Face and
The Incredible Elopement of Lord Peter Wimsey. Listening to the first part of Bone I can't help thinking it would benefit from the attentions of the BBC Radiophonics workshop. Also, Wimsey's voice is a bit low. However these details naturally loom large when I understand one word in ten.
