So i showed up at my high school reunion and before i came a got this weird letter it kinda of loos like the puzzles my old teacher gave out before she went missing her name was Mrs.Debolt. I was asking around and oddly enough all my old best friends had it so we decided to get the gang back to together and solve one more mystery there was me Fred, my wife Dalphie, Shaggy Scooby and Velma we decided to do this mystery cause this was the only mastery that we hadn't solved while being in high school.
