Hold on to your seats, Castle fans! Castle Season 5, Episode 15: “Target” airs tonight and we can barely contain ourselves.

In tonight’s all-new, drama-filled episode, we encounter a murder case that puts our favorite detectives and mystery writer on the heels of the kidnapping of a wealthy Middle Eastern businessman’s daughter. The case becomes even trickier when Castle’s own daughter, Alexis, gets mixed in the madness.

And if you’re hoping for a resolution tonight, forget it. “Target” is merely part one of the season’s two-part episode. We don’t know about you, but we can’t wait!

Nip/Tuck’s Dylan Walsh guest stars as FBI Agent Harris, an even-keeled professional brought in to help find the kidnappers.

Castle Season 5, Episode 15: “Target” airs tonight, Monday, February 18, 2013 at 10 p.m. on ABC. Will you tune in?
