The Young and the Restless's Camryn Grimes is jumping to another CBS show for a guest spot.

The actress will be appearing on NCIS in the October 22 episode, and CBS has released a look at the investigation that brings the team into contact with her character, Marine Corporal Laney Alimonte. According to the episode's logline, "evidence suggests she murdered her neighbor while being treated for insomnia by a hypnotherapist."

We haven't seen nearly enough from Ziva in Season 17.

As the photos from "Wide Awake" suggest, the team is going to be searching her house — and refrigerator — for clues. And in the promo (below), we learn her fingerprints are on the murder weapon, but she may have been hypnotized to kill. Laura San Giacomo returns as Dr. Grace Confalone; will she be able to help Laney and the team solve this case?

Elsewhere in the episode, Gibbs (Mark Harmon) befriends his new neighbors after the nine-year-old's baseball crashes through his window. Click through the gallery above to see Gibbs playing catch with the kid.
