Things won't be all fun and games when Castle returns. In a new promo for the show's eighth season, you can get your first look at how Beckett's settling into her new place as Captain, Toks Olagundoye's role as investigator Hayley Shipton and Alexis taking on a bit more responsibility with her dad's P.I. business.
Check out the promo below, which packs in a lot: Why is Castle feeling threatened by his new P.I. partner? Who's looking for Beckett? And what's with the tarantula? (Is that really necessary, villains of the world?)
Castle returns Sept. 21 at 10/9c on ABC. What do you want to see in the new season?
