When the ABC drama resumes Season 5 this Monday at 10/9c — and in addition to the well-promoted “Three’s a crowd” hullabaloo with Rick, Kate and Meredith — General Hospital vet Grahn plays Samantha Voss Peterman, a wealthy divorcee caught in a “War of the Roses”-like struggle with her “jackhole” of an ex. When Samantha’s underperforming divorce attorney turns up dead, she fields a few questions from Beckett and Castle, all while wielding a mean carpet knife.
