Description: The Adoration of the Mystic Lamb belongs to the most important pieces in the Belgian history of art. However, the beauty of this masterpiece has been overshadowed by one of the greatest art thefts of our country. Two years after its completion, two panels were stolen. More than 75 years later, still one panel is missing. A. Goedertier, an exchange broker, confessed the crime during his final moments but he never had the chance to tell where he had hidden the Just Judges. Up till now, multiple attempts have been made to discover its location. But the clues, hidden in some letters, seem incomprehensible. Can you solve the mystery and retrieve what has been lost for decades?
