Mr. Monk and the Earthquake

T1, E11: When a minor earthquake rocks San Francisco, trophy wife Christina Rutherford seizes the opportunity to bludgeon her husband Henry to death with a handy marble statue. Afterwards, she topples a huge wooden display case onto his body so it will appear he died during the earthquake. It's a crime of opportunity. A perfect murder. Or so Christina thinks. Amy Sedaris guest stars as Sharona's free-spirited sister, Gail.
