Terrifically popular science fiction novel by renowned writer H.

G. Wells, about a scientist discovering how to achieve invisibility.

But, in his case, being out of sight evidently does NOT mean out of mind.

The Invisible Man of the title is Griffin, a scientist who has devoted himself to research into optics and invents a way to change a body's refractive index to that of air so that it absorbs and reflects no light and thus becomes invisible.

He successfully carries out this procedure on himself, but fails in his attempt to reverse the procedure.
