The mystery fiction genre usually involves a puzzling situation, crime, or mysterious death to be solved. From the Latin word "mysterium", meaning secret thing, this category of books is filled with titles that can include everything from classics to police procedurals, hard-boiled detective novels to supernatural mysteries. What they all share, and what makes them so enjoyable to read, is that they turn the reader into a detective. Who, what where, when, and why did a particular crime happen? And will you be able to solve the mystery before the book ends or will the author keep you guessing with every turn of the page?
