“Chuck” actress Yvonne Strahovski is set to star in season seven of Showtime’s award-winning serial killer drama “Dexter.” The leggy, 29-year-old Aussie will play a “strong and independent woman with a murky past” named Hannah McKay.

TVLine.com reports that the Hannah McKay character will be part of a multi-episode arc that finds her helping Miami Metro Homicide with a murder case, but whom Dexter (Michael C. Hall) suspects as having a secret agenda.

Strahovski joins a cast of newbies that includes Ray Stevenson as an Eastern European crime syndicate member visiting Miami to avenge the death of an associate, Katia Winter as a Russian stripper and Jason Gedrick as the owner of the nudie bar where Winter shakes her money-maker.

“Dexter” season seven premieres on Sept. 30.
