Woman Realizes That Her House Is Linked To A Dark Past Regarding The U.S. History

Gold? Or Something Different Entirely

Alex had a clear picture in her mind of the room and while picturing it she remembered that this house has a stone wall that had some loose stones in it. Could those be the small spaces where the gold is hidden? She was intrigued by the thought but she can’t do anything about it because of what Jerry said, If excavation was done further then it could damage the whole foundation of the house.
Rachel also told about the other angles behind the room, “[maybe] somebody was paranoid and hiding gold”  or maybe the family was hiding something different other than gold or it was just a storage room. But why to hide the storage room under the basement?
