Exclusive: Castle Books GH's Nancy Lee Grahn For War of the Roses-Esque Episode

General Hospital’s Nancy Lee Grahn is heading to ABC primetime in early 2013 via a guest stint on Castle, TVLine has learned exclusively.

The two-time Daytime Emmy winner will play Samantha Voss, a wealthy, recently divorced woman, caught in a hilariously ill-willed War of the Roses struggle with her ex-husband (played by Weeds‘ Brendan Ford.)

The episode, titled “Significant Others,” is slated to air in early January.

Grahn isn’t the only soap vet appearing in the episode. The actress’ former Santa Barbara co-star, Jack Wagner, is confirmed to play a famous golfer whose wife turns up dead.
