From the wife of a king to the nanny of a serial killer...

Maria Doyle Kennedy, best known for playing Henry VIII’s first wife, Catherine Aragon, on The Tudors, has landed a role on season five of Dexter.

The Irish actress will help raise Dexter and Rita's kids in the fall, coming on board the Showtime hit as a part-time nanny. Guess Deb and Dexter can't do it by themselves, after all.

Dexter Quotes

I love Halloween. The one time of year when everyone wears a mask... not just me. People think it's fun to pretend you're a monster. Me, I spend my life pretending I'm not. Brother, friend, boyfriend - All part of my costume collection. Some people might call me a fraud. Let's see if it will fit. I prefer to think of myself as a master of disguise.

Dexter Morgan

Tonight's the night. And it's going to happen again, and again. It has to happen. Nice night.
