paul is a tall freckled six-year-old with poor eyesight. One day, his father sends him on a children's tour of the museum where he works. The guide is a gray-haired old man. He taps the tip of his cane against the floor for attention. Paul watches engineers use pulleys to lift a fossilized dinosaur. He also sees a stuffed girraffe in a closet and peers into drawers full of feathers and glass eyeballs. The guide shows him rare s from Brazil and a meteorite in a glass case that he claims is as ancient as the solar system itself. After leading Paul down two twisting staircases and along several corridors, he stops outside an iron door with a single keyhole. "End of tour. This is the way out," he says.
