Mr. Monk and the Captain's Wife

A tow truck driver is shot dead by a roadside sniper. His truck then careens off the road and crashes into Karen Stottlemeyer's (Glenne Headly) oncoming van, leaving her in a coma. Monk, most interested by the fact that the shooter and the driver were barefoot, must find out what really happened and keep Leland from doing something that could cost him his badge.
