The Four-Hour Fugue

"The Four-Hour Fugue" is a science fiction short story by American writer Alfred Bester, originally published in Analog Science Fiction and Fact in 1974. It deals with the mysterious behaviour of a valuable scientist and his relationship with the private investigator tasked with investigating him.

Plot summary
Blaise Skiaki is a brilliant perfume developer, an industry which has become vitally important since water scarcity has made regular bathing impossible for most people. Skiaki's employers have become concerned about his erratic behaviour, in particular his habit of disappearing for several hours some nights, which they initially suspect to be evidence of corporate espionage of some kind. They hire Gretchen Nunn, a famed private investigator, who becomes Skiaki's lover and discovers that he vanishes for exactly four hours every time, that he appears to be in a fugue state during these periods, and that every state terminates with a murder. She is, however, unable to trail him in order to determine whether he is responsible for the murders himself.

During this time, Skiaki gives Nunn a jewel, which she wears in her belly button. She encounters him during his fugue state and hears him refer to himself as Mr. Wish. She eventually discovers that his talent for perfumery has led to him being able to detect human pheromone trails, and that he is following the trails of individuals who have a death wish.

Before Nunn is able to act on this information, Skiaki reveals to her that she is in fact blind, something she is unaware of due to a telepathic ability to view the world through the eyes of others. Horrified by this revelation, Nunn flees, only to be confronted by Skiaki in his murderous Mr. Wish persona. Several other men appear, and reveal in conversation with Mr. Wish that they are the ones responsible for the murders, having followed him each time he goes into a fugue state, though their motivation is not made clear. They strip Nunn of her clothes, and the sight of the gem in her belly button prompts Skiaki to escape from his fugue state and aid her in overcoming her attackers.

Skiaki is able to return to work, apparently in control of his fugue states now. He and Nunn discuss their shared revelations regarding their own natures, as well as their future, eventually deciding to continue their romantic relationship.
