At the annual diamond fair, valuable objects are displayed. Visitors marvel at the beautiful items in the showcases. The museum director proudly watches as the treasures from his museum are showcased. From an office, a security company monitors the event to ensure nothing goes wrong. In the middle of the afternoon, the alarm goes off! One of the objects has been stolen! Everyone present on the exhibition floor has a different interest: the thief wants to collect as much loot as possible, the police are looking for clues, the insurance agent wants to secure the most expensive items, and ordinary visitors want nothing to do with this crime. What role do you play? And how do you score points with it?
