James Holden, angry, silently, unseen by the preoccupied workers, stole across the room to the main switch-panel, flipped up a small half-concealed cover, and flipped a small button.
There came a sharp Crack! that shattered the silence and re-echoed again and again through the room. The panel that held the repeater-circuit of the Holden Educator bulged outward; jets of smoke lanced out of broken metal, bulged corners, holes and skirled into little clouds that drifted upward—trailing a flowing billow of thick, black, pungent smoke that reached the low ceiling and spread outward, fanwise, obscuring the ceiling like a low-lying nimbus.
At the sound of the report, the man in the chair jumped as if he'd been stabbed where he sat.
"Ouyeowwww!" yowled Brennan in a pitiful ululation. He fell forward from the chair, asprawl on wobbly hands and knees, on elbows and knees as he tried to press away the torrent of agony that hammered back and forth from temple to temple. James watched Brennan with cold detachment, Professor White and Jack Cowling looked on in paralyzed horror. Slowly, oh, so slowly, Paul Brennan managed to squirm around until he was sitting on the floor still cradling his head between his hands.
James said, "I'm afraid that you're going to have a rough time whenever you hear the word 'entrenched'." And then, as Brennan made no response, James Holden went on, "Or were you by chance reading the word 'pedagogue'?"
At the word, Brennan howled again; the pain was too much for him and he toppled sidewise to writhe in kicking agony.
James smiled coldly, "I'm sorry that you weren't reading the word 'the'. The English language uses more of them than the word 'pedagogue'."
With remarkable effort, Brennan struggled to his feet; he lurched toward James. "I'll teach you, you little—"
"Pedagogue?" asked James.
The shock rocked Brennan right to the floor again.
