The first time I read Fafhrd and the Grey Mouser, I was shocked at how much it's pure D&D, to the point that I get really uncomfortable when anyone tries to say D&D is "clearly" inspired by some other author. (Which isn't what anyone is doing here.)
I can't recommend the latter Fafhrd and the Grey Mouser books, which get weird and gross the way the last few Heinlein books do (something about fantasy and sci-fi authors of a certain generation deciding to write material for their own sexual gratification, including stuff that's illegal or at the very least very gross). But the first several books are astonishing and are as close to an approximation of OD&D through pre-Dragonlance 1E as it's possible to imagine. When the books start to get boring, stop, because on the far side of that, they just get unpleasant.
The first several books are really, really good, though.
