Nicolette Scott and her father are both archaeologists, but with differences. Professor Elliott Scott lives and breathes very early Americans, like the Anasazi. His digs are in the southwest, where the ancient peoples lived. To him, his daughter Nicky's area of concern is not to be taken at all seriously. Nicky goes for the culture embodied by artifacts from the twentieth century -- a crashed plane from either World War is enough to send her senses tingling. So when she discovers a 1937 Packard convertible hidden in a sealed cave in the Utah desert, she is ecstatic. It's only when she begins to read through the papers hidden under a seat cushion that the thrill turns to something very like a chill. If those papers are genuine, they represent a huge find for Nick. But they also represent one of the most scandalous secrets in our country's history.
