Castle: Scoop on episode 6x06 and scoop on the possibility of a two-part episode in season 6 from TVLine's Matt Webb Mitovich

Got anything for Episode 6.06 of Castle? It seems to be a huge secret. No title, no synopsis, no nothing. –Susan
Oh, you’ve (likely) heard about Episode 6, you just don’t know it. That hour “has a touch of National Treasure and a touch of Da Vinci Code,” series creator Andrew W. Marlowe tells me, echoing some earlier pre-season interviews. “It’s a really fun, delightful, classic Castle episode.”

Will Castle Season 6 have a two-parter? –Vanessa
Marlowe seems iffy on the prospect of continuing that tradition, if only because the season premiere (airing Sept. 23 and 30) checks off the two-parter box. “If we have a compelling enough reason to do it, we might,” he allows, “but there are other really interesting ideas that we have on the drawing board for February that may be as fun as a two-parter, yet different.”
