Talk about killer casting: Chuck MVP Yvonne Strahovski is joining Dexter‘s upcoming seventh season for a multi-episode arc.

She will play the role of Hannah McKay, a strong, independent woman with a past that she’s struggled to put behind her. As a turn of events leads Miami Metro Homicide to ask for her help in solving some old cases, Dexter works with her and begins to wonder if there’s more to this woman than she’s professed.

Previously announced recurring players for Season 7 (premiering Sept. 30 at 9/8c) include Jason Gedrick, Rome‘s Ray Stevenson, and Swedish-born actress Katia Winter.

Strahovski recently completed work on two films, the Seth Rogen comedy Guilt Trip and the thriller I, Frankenstein opposite Aaron Eckhart.
