It's off to Atlantic City for Castle and company this week.

On tomorrow night's "Heartbreak Hotel," a casino owner is founded dead, with leads emerging in both New York and this gambling hot spot in New Jersey. Guess which one Rick chooses to follow.

With Beckett and Gates in The Big Apple, Castle will throw an impromptu bachelor party for Ryan on the episode, while Richard Burgi guest stars as a shady businessman. Enjoy the official ABC promo now:
