24's Sarah Clarke Joins NCIS

There's a new tough-talking FBI Special Agent heading to NCIS.

24alum Sarah Clarke has been tapped to play Tess Monroe, a "quick-witted, tough and shrewd" Special Agent who recently transferred to D.C. from New York City, TVGuide.com has learned.

According to a character description, Tess is "a multiple divorcée who's as sexy as she is strong. Tess has no kids so she views her fellow agents as family. Beneath a no-nonsense shell, Tess has a big heart. She believes in honor and justice and doing what's right. And she'll fight to protect those values, and her team, with fierce determination and a tinge of sarcasm along the way."

Best known for playing duplicitous Nina Myers on 24, Clarke has also appeared on Bosch, The Tomorrow People, Covert Affairs, Men of a Certain Age, and in the Twilightfranchise.

"We feel so fortunate to have Sarah Clarke joining us to play Tess," NCIS showrunner Gary Glasberg said in a statement. "I've been a fan of hers going back to 24 and more recently Bosch. She's a gifted actress, a total pro, and we can't wait to introduce her to our NCIS family and have some fun."

For now, Clarke is booked as a guest star and Tess will appear on the final two episodes of NCIS' current season, but it's possible that she could become a series regular. Will she be able to fill the void left by Tony DiNozzo?

NCIS airs Tuesdays at 8/7c on CBS.
