Castle - Mondays @ 9 p.m.
When viewers first met Richard Castle, a famous mystery novelist, he was creatively blocked. But when the NYPD questioned him in connection with a series of murders staged to imitate crime scenes from his books, Castle found inspiration in NYPD Detective Kate Beckett. 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. In the Season 7 finale, Castle revealed some of his backstory for becoming a mystery writer, while Beckett was faced with a choice about her future — will she choose to pursue a new challenge or stay where she is?
