After four seasons of "will they" or "won't they," Richard Castle and Kate Beckett finally gave in to their feelings for each other in the much anticipated Season 4 finale.

Season 5 picks up on the proverbial morning after, with Castle and Beckett facing new questions -- Was this a one-time fling, or are they now a couple? But before they find the answers, they must take on the forces responsible for Beckett's mother's murder that now threaten Kate Beckett's life.

There are two kinds of folks who sit around thinking about how to kill people. Psychopaths and mystery writers. I'm the kind that pays better. Who am I? I'm Rick Castle. Every writer needs inspiration. And I found mine. And thanks to my friendship with the mayor, I get to follow her around. And together we catch killers.
