Query: Good stuff!

This is one of Leonard's early crime novels when he made the transition from westerns, and though the setting is contemporary, in many ways CITY PRIMEVAL feels like a western, and that's a good thing. Law man vs. bad man in gritty urban Detroit-- a simpler structure than his later books that featured motley crews of bad guys. The dialogue is right on the money, the plot suspenseful. It has everything you could ask for in a good crime book. Compared to a lot of the dreck that passes for crime fiction these days, it's a gem.
