From somewhere outside the school building came the wail of a deep-throated alarm. Both Miss Terry and Paul were on their feet and by their expressions, terrified.

"The Atavars!" Paul cried, his entire body shaking.

"To the basement, Paul!" Miss Terry's face was blanched as she grasped Paul's hand and headed toward the door. But halfway there, both came to a halt, breathless and staring.

A powerful bearded man strode into the classroom.

Paul and Miss Terry fell back as he advanced. He was a man of about fifty, his bushy hair shot with gray, his eyes cold and blue. He was followed by two younger men who studied Paul and Miss Terry with interest. All three wore rough work clothing.

The bearded man pointed at Paul. "There's the boy," he said quietly. "Take him."

Paul let out a shriek of terror and fled into a corner as the two men advanced. He clawed futilely as they laid hands on him. "For God's sake, shut up," one of the men said with more disgust than anger. He pinioned Paul's arms while the other man bound them together with a strip of cloth.

Miss Terry meanwhile had collapsed into her chair. One of Paul's captors glanced at her and spoke to the bearded man. "What about her?"

The bearded man stepped close to Miss Terry and put a hand on her shoulder. She recoiled as from a snake. "How old are you?" he asked. Miss Terry made some inarticulate squeaks and the man spoke more sharply. "When were you born?"

"Two thousand four," she managed to stutter.
