7 Things to Know About Castle’s “Dead From New York”

Castle doffs a fondly satirical cap to Saturday Night Live with next Monday's installment "Dead From New York."

This lighthearted episode -- surely the calm before next week's storming finale "Hollander's Woods" -- sees Castle and Beckett investigating the murder (described as "a jack in the box from hell" by castle) of Sid Ross, the tyrannical creator of Saturday Night Tonight, a long-running comedy sketch show.

With a list of suspects as large and colorful as the team of actors, writers and comedians behind the show, it's going to take every ounce of concentration to catch this killer - and not become starstruck along the way.

We've seen the episode a little earlier than most, thanks to our partners at ABC, and have compiled a list of juicy tidbits (one for each season of the show to date) for your entertainment below.

As usual, there are no major spoilers or reveals here. We're not about to ruin your enjoyment with whodunnits, whydunnits or even howdunnits. That said, if you are a major spoilerphobe, proceed with a modicum of caution.
