Looks like Shark caught a live one!

Sources confirm to me exclusively that the CBS legal drama has tapped Paula Marshall to temporarily replace the show's maternity-bound leading lady, Jeri Ryan. Marshall is expected to appear in at least three of this season's final four episodes.

Marshall's character, a state deputy attorney general, first meets Shark (James Woods) at his disbarment arraignment, where she.... I better stop there. Too spoilery. Let's just say the two forge a mutually beneficial partnership.
