With the death of Capt. Montgomery in the 'Castle' season finale (uh, two-month late spoiler alert), the ABC cop-show-with-a-twist is getting a brand-new boss -- a woman.

According to TV Guide, former '24' star Penny Johnson Jerald will head up the 12th Precinct as Victoria Gates, whom the site describes as "a career-minded cop who spent much of her early career in Internal Affairs."

Contrary to Castle's buddy-buddy relationship with Montgomery, the writer and his detective shadow-ee, Beckett, will butt heads with the no-nonsense boss.
