This is a natural for New York City, the boroughs and the closest suburbs. It's even a good bet well beyond the fringes of Manhattan-style smog, because there's something about a uniform...something about the hint of danger and courage in police work... and don't discount Slobodkin's text and lighthearted, swiftly drawn illustrations. Text and pictures add up to an introduction for the youngest readers in this age group. There is a compressed history of police organizations since antiquity and a brief dossier (almost too brief in some cases) of the special squads that make up the detective division. The book ends with a runthrough of the organization of the New York Police Department in simple, declarative sentences, which carries the idea of the complexity of it all.
