'Game of Thrones' Michelle Fairley joins USA's 'Suits'

That was fast: Michelle Fairley has booked her TV return.

The Game of Thrones actress has been snatched up by USA Network's legal dramedy Suits for a recurring role in season three.

She'll play Ava Hessington, a British entrepreneur who runs a successful international oil company. Faced with a lawsuit that may cost her the family business, she puts her trust in Harvey Specter (Gabriel Macht) to fight the charges against her.

Fairley will make her Suits debut in the season premiere on July 16. And she's not the only Game of Thrones actor on the show next season — Conleth Hill (Varys) will make a return appearance on the series in his guest star role as British firm head Edward Darby.

On Thrones [spoiler alert for those who have not seen Sunday's episode], Fairley's character Catelyn was devastatingly killed off when her family was betrayed at a wedding on Sunday's shocking episode "The Rains of Castamere." Her gripping performance is generating buzz that she could be a strong Emmy contender this year (read our exit interview with Fairley). The episode also saw the demise of Catelyn's son played by Richard Madden, who will star in the Discovery Channel miniseries Klondike next year.
