or was it because David decided to do really look at Paula through the glass as Ellen spent most of her working day doing. does really staring at someone in their office reveal their past crimes perhaps
It's true - but only works in offices with glass walls.
When you've finally actually looked at the person you can go to the police and see their past you can go to the police and tell them - they will then take The Seen Person to (which they will willing go to) The Random Spot, this will contain The Suspect.
At The Random Spot, he Suspect will become a Victim and The Seen Person will become Arrested Person and arrest them. Then everyone will be happy.
Mind you this only happens if you are from The Magical Land of Architecture. This is a small place found in Glasgow. Other traits of The Magical Land of Architecture are parking spots outside of exactly where you want to go, and feeling no effect from surgery, and not having to work if you need to do whatever you fancy. Plus looking stylist all the time and having enviable houses.
