I definitely get the sense that this book will have a mystery noir vibe. But these few pages don't yet give me a sense of whether that darkness will be lightened by other characters or situations. Without that lightness this genre is just too depressing for me. (I just looked up noir to make sure I was remembering my genres correctly and this definition is a nearly perfect description of the excerpt: "crime dramas, particularly those that emphasize cynical attitudes and sexual motivations". )
