"Mr. Monk and the Airplane" was well received by critics, and earned Shalhoub a Primetime Emmy Award in 2003. Plot Practical nurse Sharona Fleming (Bitty Schram) leaves to fly to New Jersey to visit her aunt. Her client and detective Adrian Monk (Tony Shalhoub) is forced to go with her, as he fears not being able to live without Sharona. While at San Francisco International Airport, a woman named Barbara Chabrol (Jennifer Dale) stands on her toes to kiss her husband Stefan (Carl Marotte). Aboard the plane, an annoying extension cord salesman named Warren Beach (Garry Marshall) does little to assuage Monk's fears. Monk quickly becomes suspicious of Stefan Chabrol after he notices that Barbara no longer needs to stand on her toes to kiss him, has "forgotten" that she ordered the vegetarian meal, knows nothing about air travel despite a frequent-flyer lapel, and claims to have "forgotten how to" speak French when an old family friend, Bernard, meets them on board. More digging convinces Monk he is on to something. Monk quickly annoys everyone and a fellow passenger informs Stefan of Monk's suspicions. Meanwhile, Bernard appears dead, probably because of a heart attack but Monk cannot guarantee it. So Monk asks Sharona to steal Bernard's wine glass and, with a lighter borrowed from Beach, proceeds to burn away the wine to reveal a mysterious liquid at the bottom. However, the flight attendant, Leigh Harrison (Brooke Adams), is alerted to Monk's use of a lighter on board, and confiscates both the lighter and the glass, dumping the liquid down the sink. Monk calls Lieutenant Disher and explains what he thinks happened. Stefan and his mistress murdered Barbara and the mistress disguised herself as Barbara.
