There's a Slasher Loose in the corridors of a large urban hospital. His knowledge of anatomy is matched by his skill with a surgical blade, and his attacks are fast, furtive, and fatal. Among a welter of suspects, it's Resnick's job to keep him from killing again.If John Harvey's novels were songs, Charlie Parker would play them. Cutting Edge sings the blues for people too bruised to carry the tune for themselves. -- The New York Times Book Review
