The treasure hunt attracts most people and our heroes: Sarah and William are no exception. But for this they don’t have to sail the seas, look for uninhabited islands, just go to a neighboring county. There is one strange mansion. They have been locked for quite some time, and before that, billionaire James lived in it. He was a little strange and eccentric. While still not old in his prime, he unexpectedly died under mysterious circumstances. His house was left without a master, since heirs cannot be found yet. But there are rumors in the village that there are treasures in the house, and those who tried to find them disappeared without a trace. Our heroes in Forbidden Treasure also want to try their luck.
