The Final Step
The two guys secured the cabin. They made sure that nobody is inside the house or around it. They even made sure that the area around the cabin is safe and removed anything that might catch fire quickly.
Then they started the fire inside the cabin. The entire time they were looking at the fire and they had firefighters on speed dial. The cabin would burn for hours and hours. The entire time they could smell something strange. After many hours, the cabin was no more.
