The Good Wife is (finally!) back Sunday, and it's bringing back one of the show's most colorful clients, Colin Sweeney (Dylan Baker).

While the alleged (but acquitted) wife-killer has long been one of Alicia's biggest admirers in the courtroom, his return isn't so friendly. Unhappy with Diane and Cary's work on his defamation case, the businessman goes behind their back to get Alicia's help. But when she refuses, Sweeney goes rogue.

Recognizing Alicia is vulnerable in her campaign for State's Attorney, Sweeney threatens to expose an extremely unsavory piece of information about her to the press. What does Sweeney know? Considering his unsavory past, we're not sure that Alicia can afford to call his bluff.

So will his blackmail plan derail Alicia's campaign? And how will she react? The Good Wife airs Sunday at 9/8c.
