Briskens Erbe [Brisken's Legacy]

The house at “Am Brückenplatz 8” was owned by the Brisken family for almost 200 years. Prosperity is a rather understated description of what is said about the family. It is rumored that many a treasure has certainly accumulated on the abandoned family estate... During renovation work, construction workers found an old chest with the inscription "My beloved Arnsberg". Did the last family members leave something valuable after all? A forgotten legacy? The responsible history office has been informed and is now asking you to reveal the secret of the chest. Your job doesn't seem too difficult: decode the statements of the witnesses, open the chest undamaged and collect the finder's reward. But you're not the only ones who got wind of the find. Shady characters are said to be on their way to the house and will be here soon. Can you secure the find before they arrive?
