Castle Season 4 Finale Spoiler: Mystery Person’s Identity Revealed!
Earlier this week, we revealed new details about the mystery person returning to Castle during May sweeps, and now we can confirm that it's none other than … drum roll, please … Captain Monty's widowed wife, Evelyn Montgomery, played by Judith Scott.
So, what brings the deceased captain's wife back to the precinct in the May 7 finale? According to show creator Andrew Marlowe, it all goes back to Roy's involvement in the conspiracy and cover-up of Johanna Beckett's murder.
“Events force us to wonder whether the case we’re working on might be linked to the Beckett’s mother's murder case," he revealed. “We’ll be picking at that scab again.”
