Imagine that you are part of an office or living group. For the last few weeks it has been strange in this group. One day some prankster set all the clocks back two hours. Then some secret admirer has been leaving little presents and cards for your friend Alex, which is a little creepy. Several people also have received fraudulent charges on their credit cards. Two of the women are not sure how their card numbers were stolen, but they habitually leave their purses in unlocked drawers. Alex had his whole wallet stolen but didn’t miss it right away. You think you may know who is responsible for the thefts. You saw Molly coming out of the door to Alex’s room the same day his wallet disappeared and know she has had money problems. But you like Molly and think she is basically a great person.
