Next week NCIS is coming back to TV with season 11's episode 10, "Devil's Triad," and it will include a murder case that has a connection to Leroy Jethro Gibbs' ex-wife.

In the episode teaser, the murderer is dressed in a clown outfit and shoots the victim who screams "No!" right before the bullet is fired.

"They all had alibis," Timothy McGee says about several clown suspects, before Tony DiNozzo jokes, "And very large shoes."

The team finds a link between the murder victim and the boyfriend of Gibbs' ex-wife Diane Sterling. She's also the ex-wife of Tobias Fornell.

"The humor that exists when these characters get together is just a blast," Executive Producer Gary Glasberg told TVLine in November.

In the meantime, the new team member, Ellie Bishop, is going to adjust to the NCIS world. Bishop, played by Emily Wickersham, made her debut on the Nov. 19 episode titled "Gut Check."
