Frances Fisher has designs on Castle Season 6.

According to William Keck of TV Guide Magazine, the veteran British actress will portray an Anna Wintour type of character, someone featured in an episode producer Andrew Marlowe describes as having a "Devil Wears Prada feel to it."

Teases Marlowe, referring to Vogue's editor-in-chief:

"In investigating the case, we discover that the Anna Wintour character, Matilda King, who runs this magazine, Modern Fashion, crossed paths with Beckett when she briefly flirted with a career as a model."

Fisher will appear on the January 27 installment of this ABC smash.

The series is currently in hiatus, but remember to watch Castle online at TV Fanatic and catch up on anything you may have missed.
