Scientific opinion was divided when, in 1864, Professor Hardwigg first told of his adventurous journey to the center of the Earth.

Should scientists believe this far-fetched tale from a member of their community? An envious rival succeeds in undermining Hardwigg’s credibility and gradually the whole story is forgotten.

The expedition is rumored to have been pure fantasy....
