On tonight’s “Castle” season 6, episode 6: “Get a Clue,” Castle and Beckett investigate the bizarre murder of a young woman who was found ritually posed. When the team finds a collection of strange symbols in her apartment and the prime suspect turns out to be a mysterious monk, Castle becomes convinced they’ve stumbled onto a “Da Vinci Code” style conspiracy. Meanwhile, Castle tries to come to grips with the fact that Alexis and Pi have moved in together.
The series is based on mystery-thriller writer Richard Castle (Nathan Fillion), who is called in to help investigate a series of copycat murders based on his books. After completing the job, he finds that he enjoys the experience enough to continue it. Pulling strings, he arranges to accompany NYPD Detective Kate Beckett (Stana Katic), claiming he wants to study and use her as a personality basis for his next book series.
Once that initial case was solved, Castle and Beckett continued to investigate strange homicides in New York, combining Castle’s writer intuition and Beckett’s creative detective work. Over the past four seasons, Castle and Beckett’s relationship has grown even stronger as they’ve dodged bullets, captured killers, and solved countless murder cases with their unorthodox partnership.
“Castle” season 6, episode 6: “Get a Clue,” airs Oct. 21, 10:00 p.m. ET on ABC. Spoiler videos below:
