Predator: Concrete Jungle is a 1995 novelization of the comic book series of the same name, written by Nathan Archer and published by Bantam Books. The story revolves around a Predator that has landed in New York City, brought there by the heat and prey. Hot on the trail of the grisly murders the creature leaves in its wake is a detective by the name of Schaefer, the brother of Alan "Dutch" Schaefer, who realises the sadistic killer is more than just another psychopath from the city, but something much worse.
With the record-breaking heat come frayed nerves and a rising crime rate. New York City detectives Rasche and Shaefer are assigned to look into the most brutal murders they've ever seen — flayed bodies hung like curing meat on a rack — and they can't believe that just an over-heated temper tantrum is the cause.
When Shaefer has a close encounter with one of the murderers, he realizes he's run into something much bigger than the police suspect. The creature leaves him with an alien device implanted in his neck and a strong feeling the fight is a personal thing.
