In Castle season 5, episode 19 “The Lives of Others,” which is the show’s 100th episode, Castle finds himself in the unfortunate position of NOT being able to work a case. While he’s holed up in the loft with a broken leg, Beckett goes off to investigate the death of an IRS agent without him, leaving Castle miserable and bored. But when he thinks he witnesses the murder of a young woman in the apartment across the street, he is thrown into a “Rear Window”-esque murder mystery that hits much too close to home.
The series is based on when mystery-thriller writer Richard Castle (Nathan Fillion), who is called in to help investigate a series of copycat murders based on his books. After completely the job, he finds that he enjoys the experience sufficiently to want 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 stars Fillion, Katic, Susan Sullivan, Molly Quinn, Penny Johnson Jerald, Tamala Jones, Jon Huertas, and Seamus Dever.
