Scooby Doo Reader Insert

You're like your cousin Fred. You both love mysteries. But, you solve mysteries on your own. Fred wants you to join the gang on one mystery that will change your life forever. This whole plot-line is my idea. If anyone copies and says it is theirs there will be consequences. This is also like the real life movies they have out there but my own plot-line. This is the first one out there like this so please don't steal my ideas.
