The museum

Aunt Klara has passed away and you are now the rightful heir to the world-famous diamond “Indian Fever.”  However, unfortunate circumstances have led to your inheritance mysteriously disappearing.  Just as you were about to come to terms with the loss of Aunt Klara (and the diamond), the missing jewel appears as an exhibit in the “Museum.”  You demand the return of your property, but to no avail.  Then you have the idea of a lifetime. You assemble a team of specialists, and one night, you all set out to work together…  Will you succeed in liberating your inheritance from the “Museum”?
