It might be variously classified as historical fiction, mystery, or science fiction.

Though the author denied that A Maggot is a historical novel, it does take place during a precise historical timeframe, April 1736 to February 1737, in England. Another meaning of the word "maggot" becomes apparent later in the novel, used by a character to describe a white, oblong machine that appears to be a spacecraft. Its title, as the author explains in the prologue, is taken from the archaic sense of the word that means "whim", "quirk", "obsession", or even a snatch of music (see earworm).

It is Fowles' sixth major novel, following The Collector, The Magus, The French Lieutenant's Woman, Daniel Martin and Mantissa. A Maggot (1985) is a novel by British author John Fowles.
