Park Ranger: Well, it's pretty obvious what happened. This is the point of origin.
Adrian Monk: [blows whistle] Natalie, right here. Point of origin. [whistle] Please go on.
Park Ranger: Well, somebody was here camping out unauthorized. Without a permit. And apparently the wind shifted from east to north.
Adrian Monk: [whistle] East to north. Got it. [whistle] Continue please.
Natalie: It's his first whistle.
Park Ranger: Well, the brush around here was bone dry. So those branches probably caught first. And then they spread downwind. And then once it hits the valley, well, there's no stopping it.
Adrian Monk: So the fire was moving... [whistle] Up the hill, that way.
Park Ranger: Yeah, are you with the arson squad, Mr. Monk?
Adrian Monk: No, no. This is a private investigation. And call me Coach. Coach Monk.
