“Castle” season 6, episode 18: “The Way of the Ninja” airs tonight on ABC.
In this episode, when Castle and Beckett investigate the mysterious murder of a Japanese ballet dancer, they end up being targeted by a ninja assassin.
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 Det. Kate Beckett (Stana Katic), claiming he wants to study and use her as a personality basis for his next book series.
After 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 18: “The Way of the Ninja,” airs March 17, 10 p.m. EST on ABC. Spoiler videos below:
