Just finished Dorothy Sayers', Clouds of Witness (you are right, Marcie). I think I will have to read another before I form a firm opinion. Lots of wonderful plot twists and clues, but I turned my nose up a little at his Lordship's conversation. It sounded so "dead common" rather than the Oxford English you might hear from an aristocratic mouth. I refer, mostly, to Wimsey's habit of endin' his endings and investigatin' rather than investigating, if you get my drift. The story lends itself well to a TV production, I think.
