Castle and Beckett had their fun over the last couple episodes of Castle Season 7 (a wedding! A honeymoon!), but it will be back to crime-solving business this Monday night.

The installment  begins like any other normal day, with Detective Esposito taking the subway to work... but things will take a dangerous turn when a armed man takes the train car hostage.

Will Javier be able to diffuse the situation before it turns deadly? Will Castle, Beckett and Ryan figure out the hostage taker's real agenda is before it's too late?

Check out these photos from Castle Season 7 Episode 8 ("Kill Switch"), which is scheduled to air on Monday, November 24 at 10/9c on ABC. Then, visit TV Fanatic soon afterward for my detailed recap and review!
