'Castle' Episode 3.13 Photos: Old Wounds and New Torture
The case of Beckett’s murdered mother is back with a bang in "Knockdown."
When an old detective is killed right before he can tell Beckett some information on the case, she and Castle delve into a conspiracy that may just have the solution to Beckett's mother's murder.
Whether they solve the crime or not, the drama of the episode may “take their partnership to the next level” (according to the press release). So that sounds good anyway.
