Season 1 of Castle premiered on March 9, 2009. The season contained 10 episodes. Initially 13 were ordered but coming shortly after the writer's strike and at a time of budget cuts, Castle's order was reduced to 10 episodes.
The premiere garnered the highest number of viewers, with 11.6 million. Each episode came in lower in viewership week-by-week until Always Buy Retail, which had the lowest of the season. Fortunately, the show bounced back enough to be granted a second season.
After killing off his most successful character out of boredom, wealthy, handsome, and charming playboy murder mystery writer Richard Castle has a bad case of writer's block at the same time as intelligent, attractive, hard-nosed HYPD Homicide Detective Kate Beckett is investigating a series of murders she recognizes as copycat killings based on Castle's books. She invites him to consult on the case and as they work together, Castle is inspired to create a new character based on her then calls in a favor from his friend the Mayor of New York City to shadow Beckett and her team for research. While Castle is thrilled with the arrangement, Beckett is furious, calling him immature and uncontrollable. Nevertheless, a hint of romantic tension courses between both of them as the season progresses. Beckett's best friend, sassy Medical Examiner Lanie Parish, encourages her to act on it while Beckett's squad members, tough ex-military man Javier Esposito and his partner and perpetual butt-of-the-joke Irishman Kevin Ryan, tease her about it. Overseeing everything at the 12th precinct, is Beckett's mentor, the good-natured Captain Roy Montgomery. On the home front, Castle's ex-Broadway Diva mother, Martha Rodgers moves back in with her son and his overachieving, level-headed, and responsible teenaged daughter Alexis after a boyfriend steals all her money. Both women conspire to keep Castle's ego in check and his life in perspective.
