7 Things to Know About “Castle, P.I.”

The holiday hiatus is finally over and that means ABC's Castle is about to hit our screens again one week from today.

When we last checked in with our favorite sleuthing duo, it appeared their joint sleuthing days might be finally over, following Rick's tricky involvement with the mob, and his subsequent ban from the 12th precinct.

"Castle P.I." sees Rick going solo as a newly minted private investigator. However when his and Beckett's investigation into the murder of an admissions director at a prestigious feeder school clash, the sparks soon fly.

Thanks to our friends at ABC, we’ve seen the episode a little earlier than most. If you’re a regular reader of our ScreenSpy articles then you’ll know we don’t go for revealing spoilers that would otherwise ruin your enjoyment of the episode (we want you to enjoy it as much as we did) but we can provide you with a number of teasers to get you in the mood for some plot-twisting, quip-flying, investigation-trumping fun come Monday.

Without further ado, here are 7 things (one for each season of Castle) to know about Jan. 12th’s “Castle, P.I.”
