'Castle' Goes 'Wolf Of Wall Street' In This Exclusive Sneak Peek

A wedding isn't the most typical topic discussed at a bloody crime scene, but that's just what makes Beckett and Castle so special.

In a new exclusive clip from the upcoming episode of "Castle," the soon-to-be newlyweds begin discussing their wedding as they arrive to a murder scene. Castle really wants to keep the invite list small (so everyone "can fit into one car," of course), but Beckett isn't really on the same page.

Caskett then check out their latest victim, a Wall Street trader who has been shot and killed, but looks to have had something hidden under his shirt. Castle seems to think the hidden treasure may have been inspired by a money-hiding trick from "The Wolf of Wall Street."

Check out the clip above before the next episode, "The Greater Good."

"Castle" airs Monday at 10 p.m. EDT on ABC
