What's On Tonight: Prime Suspect, Masterpiece Classic: Downton Abbey, Rachael Vs. Guy Celebrity Cook-Off

Prime Suspect, 9 and 10 p.m., NBC

This is me doing a happy dance, because there are two back-to-back episodes of what you know is my favorite show of 2011. This is me doing a sad slump because I think these are the last two episodes. Ever.

Masterpiece Classic: Downton Abbey, 9 p.m., PBS (check listings)

So good! Oh my! Mr. Bates! Really. Breaks my heart. Tonight, “Isobel and Cora disagree about Downton's medical role; Mrs. Bird starts a soup kitchen; Matthew and William find themselves behind German lines.”

Rachael Vs. Guy Celebrity Cook-Off, 9 p.m., Food

You knew that Miss America was going to go. You just knew. They could send home an American hero like Summer Sanders over a salad!
