Tod im Salz [Death in Salt]

During your visit to the German Mining Museum, you will receive a message from Amyra from Iran: She came across quite a few inconsistencies while browsing through her deceased father's documents - the notes are confused, important information is missing and it almost seems as if it is there not everything went right. Apparently it is about the very excavation in Chehrābād, whose finds you are about to see in the exhibition "Death in the Salt". What was the famous archaeologist on the trail of? Can you help Amyra bring light into the darkness?
