questions left unanswered in the film (spoiler alert!)
1. so did sally kill the father of the dead girl at the end; and if not what happened to him?
2. since there were around 5 victims, the father would have had to pay £5 million to each after they completed their task. did he have at least £25 million or did he get the money back from each victim after they were killed?
3. since he was testing their morality, does that mean if they had declined his offer to kill then would they have been taken off the target list?
