When viewers first met famous mystery novelist Richard Castle (Nathan Fillion) 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 (Stana Katic.
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 years they did more than just solve crimes though - they fell in love, started dating and then finally decided to get married. In the season six finale, as Castle was driving to his much-anticipated nuptials, an ominous black SUV came down on him. When he didn't show up to the wedding, Beckett was called to an accident scene where she saw Castle's car in a ravine, engulfed in flames.
So, does Castle survive... and will he and Beckett ever be able to be together?
