Well after reading through it a few times I think I finally got what was going on; your third paragraph is a confusing mess. But, I would have to say that it's pretty good. But again, I really have no idea how the women (who's child who got raped - and is also apparently disguised as a man) is going to convince #2 that they're in love or get in a verbal fight with the rapers. Tapes and letters just wont do it and niether will disguises. Therefore, I'd get rid of the twist because it's pointless and is only there to serve one purpose - to have a twist. It would be far easier to just have the pastor be the husband.
Your plot is also kind of cruel to the killers sister. I mean you have this mother seeking revenge on these pedophiles/rapists/killers because they killed her daughter. She is seeking revenge because she mourns the loss of her daughter. Then you basically have the sister pretend to fall in love with the mother (as a man i should add) and then make her think that her brothers killed her lover. What did the sister ever do to deserve the killing of her lover. You can't really feel empathy for the mother when she basically pulls a ring a round. But this could be what your going for, I dont know.
I'd also like to tell you that your title s-u-c-k-s (i can't believe you filter out this word you dirty dirty bastards). The bludgeoner sounds like some cheesy 80's horror flick. Change it.
