It's October 29,1964 and the American Museum of Natural History in New York City is closed for the night. In the darkness of night, the city lights stream through the window, gently illuminating exhibits, including… The JP Morgan Hall of Gems and Minerals. Then, a foot pokes through an open window. Two men slide down a rope and tiptoe through the room. They cut into the glass casings protecting the jewels with the ease of seasoned veterans, scooping up 24 priceless gems. The two thieves sneak back out the window and abscond into the night.
