The Mystery Of Marie Roget by Edgar Allen Poe
Personally I enjoy Dupin. I see without any doubt that Conan Doyle was influenced by Poe. Though I have to say that even if Poe had carried on with Dupin for a full series, unless he took the time to develop the friendship between Dupin his companion, Sherlock still would have been ore palatable to the public in general. Poe has a very "artistic pen" that most people would have and still would need a dictionary to understand.
This was sooooo not like any film I have ever seen of the same title. I loved this and I hated every film I ever saw of it. As I have said on more than one occasion, how did they get those movies out of this story?
