"...the serial killer novel to end all serial killer novels."
Twenty years ago John Costello's life effectively ended. Not yet seventeen, he and his beautiful girlfriend, Nadia, became victims of the dangerously disturbed 'Hammer of God' killer who terrorised New Jersey City throughout the summer of 1984. This madman targeted young courting couples in an attempt to 'save their souls'.
Nadia was killed by the first blow of the hammer. Then the killer turned his attentions to John, but despite his terrible injuries John survived. Physically and psychologically scarred to an extent that few people could understand he withdrew from the world, hid in his apartment and now only leaves his front door to work as a crime researcher for a major newspaper. Broken he may be, but no one in New Jersey knows more about serial killers than John Costello.
So, when a new spate of murders starts - all seemingly random and unrelated - John is the only one who can discern the intricate pattern that lies behind them. A knowledge that could once again bring mortal danger into his life.
