What's scarier than looking after a classroom full of second-graders, which is the situation in which Rick Castle found himself on Castle Season 7 Episode 4?
That's easy: The Internet!
On next Monday's Castle Season 7 Episode 5, aptly titled "Meme is Murder," Rick and Kate will take on the case of a World Wide Web celebrity who is found dead.
This leads them into flashy/frightening world of Internet fame.
However, when the culprit posts photos from the crime scene on a photo-sharing website, this beloved twosome realizes they are up against a social media sociopath... who may strike again.
And who may be targeting them next.
