"Suddenly he stopped and turned upon The Thinking Machine"
Dick gazed at him in surprise which approached awe. His eyes were widely distended, the lower part of his face lax, for the instant; then his white teeth closed with a snap and he sat down opposite The Thinking Machine. Anger had gone from his manner; instead there was a pallor of apprehension in the clean-cut face.
"Who are you, Mr. Van Dusen?" he asked at last. His tone was mild, even deferential.
"Was he masked?" insisted the scientist.
For a long while Dick was silent. Finally he arose and paced nervously back and forth across the room, glancing at the diminutive figure of The Thinking Machine each time as he turned.
"I won't say anything," he decided.
"Will you name the cause of the trouble you and Meredith had in Harvard?" asked the scientist.
Again there was a long pause.
"No," Dick said finally.
"Did it have anything to do with theft?"
