Gail O'Grady, Nathan Fillion
NYPD Blue vet Gail O'Grady is back on the beat — sort of. The Emmy nominated actress will guest-star on an upcoming episode of Castle, TVGuide.com has learned exclusively.
O'Grady will play Margo Cowan, one of the stars of the hit Real Housewives-esque reality show The Wives of Wall Street. The cameras follow her as she runs her cosmetics empire — an empire that employed the victim of a murder the team is investigating.

Aside from playing Blue's big-haired squad secretary Donna for three years, O'Grady is also known for her role as American Dreams' family matriarch. She most recently guest-starred on Hawaii Five-0 last year.
