The Mystery genre contains stories with narration in which one or more elements remain unknown until the end: the stories are like puzzles, where the reader is given one piece of the puzzle at a time and they have to try to work out the big picture.

Often there is a crossover with the "Crime genre" but they are two distinct genres.
