Beckett Going In All-Out War With Her Mother's Murderer In Upcoming Episode

Recently on Castle, Beckett learned the true identity of her mother's killer, Senator William Bracken, played by Jack Coleman. Since, Beckett did not have enough evidence to arrest him, things could possibly escalade in a future episode according to series creator Andrew W. Marlowe. 
"We're planing to add more significant features to Beckett's mother's mythology stuff before the end of this season." Marlowe told TV Guide "All sorts of things can happen. We still have a few tricks up our sleeve."
