In the organizer's words:

A BODY IN THE LOUVRE

1958, Paris, post-war period. In one of the most famous landmarks of the city, the Paris Louvre, Valérie La Voyante, indispensable art historian for several years, invites to a reception.
Champagne is served, small appetizers are distributed by waiters in vest and tie, because the entire haute société of the city does not miss such an event.

Mesdames et Messieurs of the distinguished, exclusive and art-aware circle meet here and discuss and philosophize about ancient and contemporary art. Everyone celebrates exuberantly until Madame La Voyante announces the surprising news that the famous "Mona Lisa" is not real. Indignation goes through the ranks. The police are called to uncover the whole thing.

After the first shock has settled, the second scandalous news rushes in:
A corpse!
A corpse in the Louvre! Who would have thought that possible? But anything is possible at this mystery dinner. Because the culprit is still in the building. So it's up to you to solve this case, because the local police are still busy finding the "Mona Lisa".
Are you ready for this crime mystery?
