From the rulebook:

Percy Pilferer is around town. The notorious pickpocket is painting the town red and has not yet been caught in the act. Bingo! He strikes again. What has he stolen this time? At this point the suitcase detectives are called in, up until now they have always managed to resolve every case; but now they need your help. Can you recognize which objects the pickpocket has stolen from the suitcase?
