What metaphors are used in The Monkey's Raincoat by Robert Crais?

Elvis Cole narrates in the tone of a classic hard-boiled detective, with a sense of wry humor and a tendency to metaphor. Elvis describes Lou Poitras as having a "face like a frying pan." He compares falling rain to bulls' hooves. His sleek metaphors paint a picture of the world around him and how Elvis sees it, while also evoking the film noir and Mickey Spillane style hard-boiled detectives of the past. The novel is full of short sentences and pointed sentence fragments, as it follows Elvis's train of thought.
