Chuck Star Yvonne Strahovski Joins Dexter

Yvonne Strahovski, best known as CIA operative Sarah Walker on NBC's Chuck, has landed a multi-episode arc on the upcoming season of Dexter, Showtime announced Tuesday.
Strahovski will play Hannah McKay, a strong, independent woman with a violent past that she's struggled to put behind her. Dexter (Michael C. Hall) crosses paths with Hannah when Miami Metro Homicide seeks her help in solving old cases. He'll eventually question whether there's more to Hannah than she's admitted. As TVGuide.com previously reported, Hannah has a violent past that she's trying to keep quiet.

Production on the seventh season of Dexter began last week. It premieres Sunday, Sept. 30 at 9/8c on Showtime.
