The Invisible Man is a science fiction novel by H. G. Wells. Originally serialized in Pearson's Weekly in 1897, it was published as a novel the same year. 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 neither absorbs nor reflects light and thus becomes invisible. He successfully carries out this procedure on himself, but fails in his attempt to reverse it. An enthusiast of random and irresponsible violence, Griffin has become an iconic character in horror fiction.

While its predecessors, The Time Machine and The Island of Doctor Moreau, were written using first-person narrators, Wells adopts a third-person objective point of view in The Invisible Man.

A mysterious man, Griffin, arrives at the local inn owned by Mr. and Mrs. Hall of the English village of Iping, West Sussex, during a snowstorm. The stranger wears a long-sleeved, thick coat and gloves; his face is hidden entirely by bandages except for a fake pink nose; and he wears a wide-brimmed hat. He is excessively reclusive, irascible, unfriendly, and an introvert. He demands to be left alone and spends most of his time in his rooms working with a set of chemicals and laboratory apparatus, only venturing out at night. While Griffin is staying at the inn, hundreds of strange glass bottles (that he calls his luggage) arrive. Many local townspeople believe this to be very odd. He becomes the talk of the village with many theorizing as to his origins.

Meanwhile, a mysterious burglary occurs in the village. Griffin is running out of money and is trying to find a way to pay for his board and lodging. When his landlady demands that he pay his bill and quit the premises, he reveals part of his invisibility to her in a fit of pique. An attempt to apprehend the stranger is frustrated when he undresses to take advantage of his invisibility, fights off his would-be captors, and flees to the downs. In the process, he arms himself with an iron pipe; when a man follows the "floating pipe" and accidentally forces the Invisible man into thorn bushes, the invisible man commits his first murder.
