Archibald's Inheritance

You are enjoying an evening entertaining friends when there is a knock on the door. You answer the door to see a very serious looking man in a suit dragging a very old chest behind him. Nervous, you are about to shut the door when he speaks. “Wait!” he says. “I’m here to inform you that your Great Uncle Archibald has passed away.” You search your mind but can’t remember ever hearing about a Great Uncle Archibald. Assuming this is a scam of some sort, you are about to shut the door when the man speaks again. “You probably don’t know him,” he continues, “because he left the family when he was young. Felt he was smarter than all of you. Made a fortune on the other side of the country, but never married and never had any children. I was his lawyer, and I was the closest he had to a friend. I am also the executor to his will.” Curious about this fortune, you decide to listen. “He left you this chest. Inside is a small safe, and inside of that is a piece of paper with his list of bank accounts and authorizations. Once I set this chest down, the timer inside will activate, and you will have one hour to retrieve the bank account information with all the access to his bank accounts worth over $100 Million. He wanted someone in the family to prove thatBut be warned, after an hour, there is a vial of acid in the safe that will burn the paper. Likewise, three wrong attempts to open the safe will also open the acid and burn the paper. Your friends here can help you. “This chest is quite heavy, and I’d quite like to put it down. Are you ready to begin?”
