Jules Verne,
A Journey to the Centre of the Earth
(1871)
“ What horror and stupefaction took possession of my soul. I was like a man who had received a knock-down blow. Was it possible that I really read the terrible secret, and it had really been accomplished! A man had dared to do—what?No living being should ever know."Never!" cried I, jumping up. "Never shall my uncle be made aware of the dread secret. He would be quite capable of undertaking the terrible journey. Nothing would check him, nothing stop him. Worse, he would compel me to accompany him, and we should be lost forever. But no; such folly and madness cannot be allowed." ”
