Mona Moon is not your typical young lady in the 1930s. She is a scholarly cartographer by trade, an intrepid explorer by nature, and an ardent adventurer by heart. But there's a problem. Miss Mona is broke. It's during the Depression, and her application to join an expeditionto the wilds of the Amazon has just been turned down. What's she to do?Perhaps get a job as a department store salesgirl. Anything to tide her over until the next assignment. There's a knock on the door. Who could this be in the middle of the night? Mona doubts it would be a friend.Holding a revolver, Mona reluctantly opens her door to a man wearing a Homburg hat and clutching a briefcase. "I bring grave tidings. Your Uncle Manfred Moon has died and left you as his heir to the Moon fortune. You are now one of the richest women in the country!" he says.Mona's response is to point her revolver in his face. If the stranger is telling the truth, she will apologize. If he is a fraud, she will shoot him. That's how the lovely Madeline Mona Moon does things in 1933.
