“Castle” season 6, episode 19: “The Greater Good” airs tonight on ABC.
In this episode, Castle and Beckett investigate the murder of a Wall Street trader, but the case takes a shocking turn when the they discover the victim was an undercover informant for the U.S. Attorney’s Office. To complicate matters further, the U.S. attorney involved is Elizabeth Weston, Capt. Gates’ estranged sister.
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.
