dexter yvonne strahovski 'Dexter' Season 7: Yvonne Strahovski cast as aide to Miami Metro HomicideThe “Dexter” Season 7 guest-stars are starting to roll in – Jason Gedrick (“Murder One”) has already been cast as a Miami-area “gentlemen’s club owner.” Now Showtime announces Yvonne Strahovski has been cast as Hannah McKay, a strong woman whose past continues to haunt her.

A turn of events leads Miami Metro Homicide to ask Hannah for help in solving some old cases. As Dexter works with her, he begins to wonder if there’s more to her than meets the eye.

Oooh, intriguing. We wonder what it is about Hannah that leads Miami Metro to ask for her help.

Strahovski is best known for playing the kick-butt spy Sarah Walker on NBC’s action-comedy “Chuck,” which wrapped its final season earlier this year. Are you excited to see her on “Dexter,” fans?

“Dexter” will return Sunday, Sept. 30 at 9 p.m. ET/PT on Showtime.
