The Big Sleep (by Raymond Chandler)
I thought the book was boring, though, and a little confusing. I didn’t understand anyone’s motives all that clearly, least of all Marlowe’s. I thought some of his metaphors (those famous noir metaphors) were stretched pretty thin. It wasn’t that suspenseful or exciting because I didn’t actually care about anyone. It had its moments, but overall, it seemed more “important” than actually good. I far preferred The Maltese Falcon.
[Edited to add that I just went looking around the Amazon reviews, and the consensus is that his later books are much better. There are a lot of four-star reviews glowing about Chandler but then admitting that his plot makes no sense. So, yay! Not just me.]
