I'm eager for the chance to spend time with my handsome friend Lee Gorham, but a surprise request is made just at the moment the priceless diamond disappears. At the last minute, I jump onto another train heading south, but a strange turn of events might not only derail my plans but threaten my life, too. Can Dad and I find the missing piece to the puzzle before the diamond and I are both gone for good?
