Katie Holmes will join the third season of Showtime's hit series Ray Donovan in a significant guest-starring role.

Holmes, the TV, film and Broadway star, will portray shrewd, chic businesswoman Paige, the daughter of billionaire producer Andrew Finney (Ian McShane), who enlists Ray’s services.

The network’s second highest-rated drama series behind Homeland, Ray Donovan is currently in production in Los Angeles.

Set in the sprawling mecca of the rich and famous, the series stars two-time Golden Globe nominee Liev Schreiber as L.A.’s best professional fixer, the man called in to make the city’s celebrities, superstar athletes, and business moguls’ most complicated and combustible situations go away.  During the second campaign, Ray’s life was disrupted when the FBI, his father Mickey (Jon Voight, in his Emmy-nominated and Golden Globe-winning role), and his own family slip out of his control, testing his roles as protector, provider and patriarch like never before. 

The cast also includes Paula Malcomson, Eddie Marsan, Dash Mihok, Steven Bauer, Katherine Moennig, Pooch Hall, Kerris Dorsey and Devon Bagby. The third season comprises 12 episodes.
