Castle First Look: Devious Dr. Nieman Returns — And Is She Not Alone...?

On the Feb. 9 episode of ABC’s Castle, the doctor is (back) in. And she may have brought a “familiar” friend with her.

In the sweeps episode “Resurrection” — which kicks off the procedural’s annual two-parter — when clues in a murder implicate Castle and Beckett’s onetime nemesis, Dr. Kelly Nieman (returning guest star Annie Wersching, 24), private eye Castle is called in to consult on the case. But as the team delves deeper into the investigation, they uncover connections to notorious serial killer Jerry Tyson.

Is the nefarious 3XK indeed among the living? Or, could this be some fiendish scheme of elite plastic surgeon Dr. Nieman — who previously was investigated for creating Espo and Lanie lookalikes — to upend Castle’s world? Check out the fresh photos below, and you tell us.
