Castle (2011)

After a serial killer imitates the plots of his novels, successful mystery novelist Richard “Rick” Castle gets permission from the Mayor of New York City to tag along with an NYPD homicide investigation team for research purposes. A “guy’s guy”, he proves popular with the male team members, but immediately offends the sensibilities of the team leader, Detective Kate Beckett. Though she’ll never admit it, he slowly wins her over with his innovative approach to crime solving. He brings to the table skills the others don’t have: contacts in Manhattan high society, free-form creative thinking, and years of developing believable fictional characters that have inadvertently molded him into a natural criminal profiler.
