Exclusive First Look: Castle's Official Key Art Points to a Season of Secret… Love Affairs?

Castle is giving us another mystery to chew on as we approach its Sept. 19 return: What clues, if any, can be gleaned from the official Season 4 poster?!

To best answer that question, one first must determine what exactly is happening in the image below. Given where things left off in May — with Castle confessing his love to a near-dead Beckett — conventional wisdom suggests that she’s shushing him before he opens his mouth (and heart) any further. Of course, that assumes she even heard him in the first place.

It’s also possible, particularly given the mischievous look on their faces, that Beckett is trying to stop Castle from taking their forthcoming secret love affair public! That scenario also plays into the intriguingly punctuated “Partners. In Crime” tagline in that it suggests they are joined both professionally and personally.

It also may just be a fun, provocative piece of art that holds no hidden meaning.
