Professor Henderson

Definition and stakes

Roy Rockwood,  Through Space to Mars; Or, the Longest Journey on Record

“ Henderson was a learned scientist who was constantly building new wonderful machines. He was working on an airship, in which to set out and locate the North Pole, when he discovered Jack and Mark, injured in the freight wreck. He and Washington White carried the lads to the inventor's workshop, and there the boys recovered. When they were well enough, the professor invited them to live with him, and, more than that, to take a trip with him North Pole. ”

“ With a disappointed look and a half sigh, the professor turned from him.
[110]
“Boys,” he said, “you have heard Henderson’s denial—now I call upon you. If anyone here knows anything about this matter, I beg him, for his own sake, to speak now. Do not let any school-boy notion against telling of another keep anyone silent. This is a very grave affair, and it is your duty to tell whatever you know about it.”
As the professor paused, Baum lifted his head and took a step forward, but the professor did not see him, and a threatening look from Henderson made him drop his eyes and keep silence.
