YOUNG READERS Atom Mystery 11 CHAPTER ONE It was only a dream. Eddie Taylor would like to have finished it, but the bar of morning sunlight poking in under the window shade pried his eyes open. Then, remembering the dream, he added, “Oh, Dad, is it all right if I use the Geiger counter today?” Eddie found it easy to believe the stories he had heard about his father being an outstanding football player in his time. Even his glasses and the gray hair at his temples didn’t add much age, although Eddie knew it had been eighteen years since his father had played his last game of college football. “You may use the Geiger counter any time you want, Eddie,” Mr. Taylor said, “as long as you take good care of it.

He plastered some water on his dark-red hair, pushed a comb through it, and shrugged as it snapped back almost to its original position. The tooth-straightening orthodontist had warned him about letting food gather around the metal clamps. It could start cavities. Finished, Eddie went out to breakfast. “Good morning, dear,” his mother greeted him, handing him a plate of eggs.
