The Good Wife didn't produce its best episode of the season this week, that's for certain. Read my problems with it in this review of "Affairs of State."

Carrie Preston will guest star as an attorney who actually defends Alicia because the Treasury Department gets involved in a case with a suspected terrorist, while Peter stars digging into Will's past.

What might he find there? View the CBS promo for the upcoming installment now.
