Only two episodes remain in Season 3 of Elsbeth, and the CBS crime procedural is saving one of the best guests for next to last. This week's mystery, titled "Catch and Kill," will put Carrie Preston's fabulously dressed sleuth on the trail of a veteran gossip columnist named Betty Heymouth, who's met all the biggest stars and dealt in their secrets. However, she may have also killed to keep her own dirty laundry under lock and key. Collider can exclusively share a new sneak peek that sees Elsbeth trying to find out as she pays a visit to the writer's home. Making it all the more exciting is that Betty is played by a famous, Emmy-winning television legend who has rubbed elbows with plenty of celebrities herself — Tracey Ullman.
