Castle Season 7 is about to go viral.

When an Internet celebrity turns up dead on Monday's all-new episode, Rick Castle and Kate Beckett will dive into the wicked ways of the World Wide Web to find out what went wrong.

However, they soon realize that their killer is a sociopath who is obsessed with social media and it appears he's reduced someone's 15 minutes of fame down to a mere 15 seconds.

When the killer's latest posts show who he plans to target next, can the team from the 12th precinct find a way to stop him? Or will their members be next?

Check out these photos from Castle Season 7 Episode 5, "Meme Is Murder," which scheduled to air on Monday, October 27 on ABC at 10/9c.
