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.
