Mr. Monk and the Election (S03E15)

Natalie is running for the school board in an effort to keep Julie's school from being closed. She's set up her office in an abandoned storefront, and she has a crew of supporters helping her with signs, mailings, and phone calls. Suddenly, shots ring out, and the office is riddled with bullets. Monk, Stottlemeyer, and Disher go to a nearby rooftop, where they find a dead security guard and a note from the sniper that demands that Natalie withdraw from the race. (iTunes)
