Castle and Kate are on a new case. This is a photo from Seaosn 7 Episode 5, "Meme is Murder."

Beckett and Castle have a few questions for an anchor in this scene. It's courtesy of the episode "Cloudy with a Chance of Murder."

What is happening to the dead woman in the car on Castle? "A Murder Is Forever" is the eighth of the show's sixth season.

Nothing to be embarrassed about here. This Diane von Furstenberg's Mikhaila ruby red wool coat is absolutely stunning and was first seen on Castle Season 4 Episode 13, "An Embarrassment of Bitches" and in several episodes since. It's a fan favorite and no one can say that Kate Beckett doesn't look gorgeous in it.

Castle tries to assuage Kate's first day jitters with a giant cupcake and another special surprise on Castle Season 8 Episode 1.

We loved Adrian Pasdar on Heroes. He comes on board Castle for a pair of February 2011 episode.

The entire Castle scene is on the crime scene in this season five photo. It is from the finale.

Tamala Jones is featured in this scene from the Castle Season 5 finale. She's checking out a crime scene.

Castle is holed up here with Beckett. The two are on the run with a witness.

Put up those dukes! Espo and Ryan are back in the 1940s in this fun look from the Castle episode "The Blue Butterfly."

Just kiss her already! Many Castle fans wanna see the show's main characters hook up.

Beckett senses tension between her and Castle and for good reason: he isn't happy about being lied to.
