What is the author's style in The Last Good Kiss by James Crumley?

The novel, like many of this genre, is narrated from the first person subjective point of view—specifically, that of Sughrue, the central character and protagonist. Cromley structures the novel in a straightforward, linear fashion—event and/or conversation leads to investigation, which leads to discovery, which leads to another event/conversation, which leads to investigation, and so on. This is the traditional structure of novels of this genre, and indeed of mystery novels in general.
