A good listen even if it didn't follow the story as closely as I would've liked.  Of course, it is difficult to get some of the details in any story into a 40 minute radio show, so it's understandable.  I do really like this story of Dupin and wish Poe had written him into more than 3 stories, but I enjoy the ones that were written.  I always think more of Hercule Poirot rather than Sherlock Holmes (due to the French sounding name) when I think of Dupin, but they all have the same type of thinking processes (starting with Dupin).
