Well big shiny gold medal for SapphireStrange on it being Spyware that CreepyHusband had installed. I'm not going to listen to anyone but you now!!! Thangyew.
But loads of other people suggested it too.
Whoa! Is that 4/5 other rapes?! I don't know what this is referring to; enlighten me? [befuddled]
Leo's speech at the police station was an act to put the police off him I didn't believe Leo at all. I think either it was an act, or Ian had been grooming/abusing him.
But why would she have a picture of herself on her own keyring, doesn't make sense. It's a pic of her and her daughter. Lots of people
have family pics like that.
Jim seemed to have met the owner of the red Clio but didn't she say he never turned up, so how did Jim know what she looked like? Yeah, I'm really confused about this. There's one other rape victim whose car broke down and one who walked home from the pub on her own, right? Which of them was the red Clio owner? Laura whatsername? But then yes, Jim wouldn't know her. Were the cops trying to trick him?
I don't at the moment think it's Jim.
I accuse Taxi Man of all of them. His wife will uncover him, although I fear she may die while doing so. 
I think Jim's a serial adulterer, although that doesn't necessarily explain Kath saying he could tear his life down.
Ed has a generally dark past but it's not him either. Is he an alcoholic? He's said before he doesn't drink, but the camera zoomed in significantly on the bottle in front of him in that scene.
Ian is a creep and possibly involved in porn/underage malarkey/both.
The vicar just wants more people to come to his church.
