Recoil

After years of waiting, Beckett finally gets her chance to take down Senator William Bracken, the man responsible for her mother's murder. Determined not to waste what might be her one and only shot at justice, she throws herself at the case—but Castle knows that there might be much greater forces at work, and that Beckett may not realize that she is in over her head until it is too late. As Beckett wrestles with the conflict between seeking her own personal revenge and her responsibility to see justice served, the 12th Precinct discovers that Bracken has become the target of an assassination and must do everything it can to save him. Once a suspect is taken into custody and the case is closed, Castle and Beckett find inconsistencies at the scene of the crime that suggest their suspect was framed, and that the person after Bracken is still at large and armed with a bomb.
