We don't know much about Castle Season 4, Episode 17, "Once Upon a Crime," but the spoilers are slowly starting to trickle.

And thanks to TV Line, we can now confirm that actress Sarah Jane Morris (NCIS, Brothers & Sisters) will guest star as someone pivotal to the investigation.

According to TV Line, Sarah will play Leslie Morgan, a woman whose sister, Amy, was found dead in Central Park.

As already know, thanks to a juicy tidbit from Castle Spoilers, the episode centers on a serial killer and his sole survivor, Charlotte, who helps the team discover an important link between all the victims. And when we say "all the victims," we mean a lot.

Hold on to your stomach, Castle fans. This is poised to be one gruesome fairytale!
