I picked this one up based on my old copy of 20th Century Mystery Writers praising "Jack Cannon" for his extreme readability--something nor normally associated with men's action series published by Leisure Books. And while this one doesn't exactly live up to this billing, it certainly is different from the usual cop-as-vigilante gore fests that filled the drugstore spinner racks in the '70s. The sniper, freshly back from Vietnam with a grudge, a brain injury, and a sniper scope is a cut above the usual lunatic with a gun, while Ryker, his cop opponent has enough bad attitude and crime fighting chops that won't pass muster in court to deliver the goods. While the body count is significant, the gore is oddly enough understated. The real grit comes from the '70s NYC atmosphere, when rats and roaches ruled and the city was covered in a layer of dog shit. Not bad.
