Castle has only been missing from our small screens for a month, but the hiatus is already taking a toll on the fans. One fan in particular made a spoilery discovery while rewatching Captain Montgomery's last moments as he addresses the envelope filled with Johanna Beckett's top secret files.
Result: The strokes of the late Captain's pen seem to indicate Richard Castle was the intended recipient.
It's already been spoiled Castle will know more about Beckett's mother's death than he lets on and as Season 4 gets rolling, new obstacles will arise.
There's a new captain in town and SHE is sure to shake things up!
