Here's the official synopsis for tonight's episode:

A desperate young murder suspect, Emma Briggs, (guest star Alicia Lagano, "The Client List,") takes hostages at gunpoint then mysteriously insists that she will only negotiate with one person: Richard Castle, on "Castle," MONDAY, OCTOBER 14 (10:01-11:00 p.m., ET) on the ABC Television Network. Billy Miller ("The Young and the Restless") also guest stars as Mickey Gerhardt, a hot headed Wall Street banker who gets caught in the hostage situation.

This has been a big season for Castle fans. Castle shocked everyone when he proposed to Beckett. But why now after 5 successful seasons? Executive producer Andrew W. Marlowe said the timing was just right

"They were coming to a point in their lives where they were asking questions. Things come up that challenge you, and you start looking at definitive choices that you're going to make that are going to send you down one road or another."

Be sure to catch Castle Season 6 Episode 4 "Number One Fan" tonight at 10 PM ET on FOX.
