Griffin, the Invisible Man. He arrives at a village inn and takes a room. Wearing dark glasses and bushy side whiskers, and having a completely bandaged head, he causes much curiosity in the village. Later, it develops that these are a disguise for his invisibility. Getting into trouble over an unpaid bill, he escapes and begins to terrify the people with his mysterious thefts. Wounded, he flees to a former acquaintance’s rooms. He reveals that, to get money for his experiments in invisibility, he robbed his father of money belonging to someone else; as a result his father committed suicide. Going thoroughly mad, he sends his former friend a note announcing that he plans to kill a man each day; his friend is to be the first victim. After a grotesque struggle, the Invisible Man is held by two men and struck with a spade by another man. As he is dying, his body slowly becomes visible.
Dr. Kemp, a physician. Griffin knew him when both were university students. To Kemp, Griffin reveals his story. Later, he says that he plans to use Kemp’s rooms as a base for his reign of terror, and he threatens Kemp’s life. Kemp goes to the police, with whose aid he finally succeeds in destroying Griffin.

After a struggle, Griffin at last unmasks and escapes in the ensuing horror and confusion.
