There's this amazing book by an arson investigator. He would always find the fire started in like the chip aisle --lots of plastic and fat. He would always find the fires started in the styrofoam aisle -- lots of plastic so combustible. He would always find these fires started upwind from housing complexes...

Oh, he also started the fires. Great book. Really takes you into the mind of a serial arsonist.

Point(s) of Origin. Enjoy! :)

He used to use a fuse. A lit cigarette with a match at the base. About a 10-15 timer. A real evil genius.
