place in the entire museum. No question. Biology of Invertebrates, on the first floor, was okay; and so was Small Mammals. On the second floor, African Mammals was kind of interesting because of the stuffed elephants and the gorilla who looked like King Kong and had a leaf sticking out of his mouth to indicate that he was a harmless plant-eater. Primates, on the third floor, wasn't too bad.
But the fourth floor was heaven. The Hall of Early Dinosaurs even had blue walls, which was what Caroline had always supposed heaven had.
She went into the blue-walled Early Dinosaur room and stood there, awed, as she always was. There, in the center, were the Stegosaurus, the Allosaurus, and the gigantic Brontosaurusâonly their bones, of courseâstanding in their huge, awkward poses.
"Hi, you guys," said Caroline. She thought of them as old buddies. She always came in to say "Hi," even when she was going to the Late Dinosaur exhibit, as she was today.
They all smiled their toothy smiles at her. Even Allosaurus, a fierce flesh-eater, looked sweet and happy and a little embarrassed, standing there without his skin, quite helpless.
Then she went over to say "Hi" to the mummified
Anatosaurus in his glass case. They had found him in Wyoming, of all places, with his skin still on. Sometimes Caroline wished her father had moved to Wyoming instead of Des Moines; she would be tempted to visit him more often if he had. There might be a mummified Anatosaurus buried in his back yard.
Finally, she walked to the end of the huge room and said, "Greetings, Jaws," to the jaws of the giant extinct shark that hung at the entrance to the room of Fossil Fishes.
The jaws just hung there, wide open, as if they were waiting for a dentist to say "Spit."
Caroline wasn't all that crazy about the shark jaws. They gave her the creeps. But she always said "Greetings" to them, politely, before she left the Hall of Early Dinosaurs. She did it for the same reason that she was always very nice to Marcia-Anne Hennessy, the worst bully in her class at school.
She didn't want the giant shark jaws, or Marcia-Anne Hennessy, ever to take a dislike to her.
Then Caroline took out her notebook and headed to her destination: Late Dinosaurs. That room was just as big, though the walls were green. And in the center, dominating the Triceratops and the two Trach-odonts next to him, stood the hideous, monstrous Tyrannosaurus Rex. Even without his skin, quite naked and with all his bones exposed, he was horrifying. It made Caroline shiver just to look at him. It also gave her a stiff neck, because he was so tall that she almost
had to do a backbend to see his face towering above her, looking down, with his sharp teeth exposed. If ever, by magic, he should come to life, Caroline thought a little nervously, he would only have to bend his mammoth neck, snap his jaws, and in one bite he could consume a whole Scout troop.
"Boo!"
Caroline jumped and dropped her pencil.
"Sorry, Caroline," said the man behind her. "I didn't mean to scare you, really."
Caroline smiled sheepishly. "That's okay, Mr. Keretsky. You just startled me. How are you?"
Gregor Keretsky was Caroline's hero. Stacy had two heroes: Woodward and Bernstein, the journalists who had broken the Watergate story in the
Washington Post.
And J.P.'s hero was Guglielmo Marconi, the Italian electrical engineer who had invented the wireless receiver. Caroline could drive her brother into a screaming rage whenever she wanted to just by referring to Goo-goo Macaroni.
But she did that only when she was driven to desperation, because she knew how sacred people's heroes were. She was lucky that her hero was right here, in the Museum of Natural History, and that he was one of her best friends. Gregor Keretsky was a vertebrate paleontologist, one of the world's experts on dinosaurs. His office was on the fourth floor of the museum, and sometimes he invited Caroline to have a cup of tea with him. She loved his office; it
