No, it's not a long lost story from those great mystery stories when I was a kid, and it's not a reboot for today's audience either. Thank goodness for the latter because a) all Hollywood wants to do anymore is fucking reboot past movies, even if it HASN'T EVEN BEEN EIGHT YEARS SINCE THE LAST VERSION, and b) a reboot for today's audiences would probably see Encyclopedia Brown, Sally Kimball and Bugs Meany involved in some sort of weird sexual threesome that may or may not involve handcuffs and a blackjack.
