I'd love to bring back Sir Conan Doyle, to see what he thinks about the Sherlock Holmes movies. I like the first, and I'm going to see the second.
I was going to say Sir Doyle, but I am of the understanding that he hated the Holmes stories after a point and wrote them solely because they made money - and, well, Holmes is the main way I'm aware of the man. He may be a jolly good character to have a beer with, though, and certainly a good deal less morbid than his counterpart in that genre, Edgar Allan Poe (for the Dupin character).
For me, it's tough. On the one hand, I want to say
Emile Durkheim, because, holy hell, his writings are so damn
INTERESTING, and oh what I wouldn't give to pick that man's brains apart for hours on end. (His being one of the founding fathers of sociology helps with that - Weber and Marx have always been fascinating if dense, and Durkheim's logic just makes so much sense to me.) I don't know French, though, so it could be like that one time I got my hands on an old-school Malleus Maleficarum only to find that the whole thing was in Latin and thus beyond my reading abilities.
On the other...
Dashiell Hammett. Oh my God, Dashiell Hammett.
