It was awesome. Four online personas. Himself, a girl, a gay rapist and a female superspy captain.
He met the guy online as himself (can't remember the name, but say the victim in all this called John).
Then he met John as the girl and befriended him and they fell in love online.
Then he met John as the gay rapist. Convinced him he had his online girlfriend captive and he'd rape her if John didn't [excuse me!!!] over the webcam ... which he did.
Then both the girl and rapist characters disappeared and it was made known online that the girl had been raped and murdered. John was really upset and all, but never called the police for whatever reason.
Then Mark met John online as the super female spy character. By this time Mark and John were friends in real life and were meeting up and stuff, but Mark was still playing the game.
The spy character kept getting John to do stuff and he was convinced because she knew everything about John (because she was infact Mark!!).
She tried to get John to [yoohoo!] Mark as a matter of national security.
One thing led to another and she then told John to buy a knife and stab mark to death at a specific place (Remember, the women is infact Mark!). She gave him a secret abort code - 6969
Mark and John go out on the day of the murder .. Mark knowing the whole point is for him to get stabbed cos he's set it up! John bottles it at the stab point and they end up in an alleyway where John eventually stabs Marks.
John keeps expecting the Spy woman to turn up and bale him out, which she doesnt. Eventually he explains the truth to the cops and they are stunned. They spend a bunch of months tracking down the internet people and realise they're all the same person, then eventually realise they are in fact Mark.
Both completely messed up in the head, and so obsessed with their online fantasy world that Mark couldn't bring himself to end his game even when faced with being stabbed to death.
........
Just slightly messed up, eh?
