In Paris, a famous Nobel prize winner was found murdered in his kitchen. The door of the refrigerator stood wide open, and a small piece of butter had fallen on the floor. On the kitchen table, there were a French-English dictionary, a mirror, a compass and a telescope. The calendar on the wall showed the page for April 2014, and next to the calendar there was a picture of Gaspard Monge. With his very own blood the dying scientist had written the following numbers onto the kitchen floor: 28-27-57-16-26-3-58.

Antoine, Bastien, Camille, Dorian, Etienne, Felice, Gustave, Justine, Ludovic, Mathieu, Nicolas, Ophelie, Pauline, Quentin, Raphael, Suzanne, Thibaut, Vincent, and Xavier.
