I think Red Jonh is Van Pelt for this:
-Jane is a boy...then Jonh is a girl.
-Her hair is a beautiful red and it is what we first draw our attention at...
-A tomboy that grew with brothers and become a police oficer.
-Van Pelt means something like "fur or someone that trades skins or animal fur."To trade skins(like a killer trading parts\playing parts).
So here we have a Red Jonh vs a blond Jane.
