Schiff will play Harper Dearing, an eccentric international businessman who is no stranger to hobnobbing with the world's elite. However, as we previously reported, he is haunted by the loss of his son, who died in a terrorist bombing some years ago. Perhaps he'll have an interesting perspective to offer the NCIS team?

"I was a huge West Wing fan," executive producer Gary Glasberg tells TVGuide.com. "Richard Schiff is a brilliantly gifted actor and I'm thrilled he's joining us for this multi-episode storyline.  The mysterious character of Harper Dearing is enormously complex and Richard will bring unexpected nuance to the part. This is a treat that will help propel us into the finale of what's been a tremendous season."  

In addition to appearing in Season 9's final episodes, Schiff may also play a part in next season's premiere.

NCIS airs Tuesdays at 8/7c on CBS. The Season 9 finale is slated to air May 15.
