Signs of betrayal:

I came home and it smelled like gasoline. I was riding with my mistress, and in order to smell the smell of gasoline, I washed my hands and soaked my lunch!
2nd In the neck (or other part of the body) scratched wound or scratches! It was a straw, and he struck him with either a sparkle paper or bricks beaten, anything else!

There are, of course, cases that actually accidentally gasoline poured on itself and injured accidentally! Sometimes these moments are worth paying attention.
