Good morning. I'm Noel King. For 40 years, a museum in the Canadian town of Vermillion had a mystery - a safe in the basement with a lock that no locksmith could crack. Last month, a museum visitor saw the safe. He put his ear up close, spun the dial and the door creaked open. Inside - well, just an old pad with restaurant orders and a pay slip from the 1970s. A museum tour guide told the CBC they'll probably just keep the safe door open from now on. Transcript provided by NPR, Copyright NPR.
