Nobody did police corruption as crisply and with such obvious delight as Caunitz. Just out in paperback, Pigtown is one of the very best thrillers by a fine writer who died in 1996. Many of the details in this story of high-level villainy at the NYPD will ring true because they come from an actual case, and Caunitz was smart enough to realize that he didn't have to gild these nasty lilies. Instead, he concentrated his energies on making Lt. Matthew Stuart as strong and accessible as ever as he traces the killer of a small-time mob figure right upstairs to the top of One Police Plaza.
