Mr. Monk and the Captain's Wife

M2, T14: After a sniper's bullet kills a tow truck driver, the truck careens into Karen Stottlemeyer's car as she is making her way to work, sending her to the hospital. As Captain Stottlemeyer grapples with the possibility of losing his wife, Lieutenant Disher speculates that an ongoing local union dispute may be behind the shooting. Eager to find the person responsible for nearly killing his wife, Stottlemeyer confronts union leader Harry Bolston at a union rally. Bolston denies any wrongdoing, and Monk believes him, suspecting something just isn't right. But Stottlemeyer's clouded judgment has made him obsessed with nailing Bolston and the union.
