Holmes' Apprentice

The adventures of a teenage detective starts again.. Conan and his friends are back from the past... This story is about Conan and his friends and how they are 19 years later, if ever, Toichi Kuruba didn't die, if there was no APTX 4869, if Akemi is alive, if Vermouth never learned disguise, if Takagi never liked Sato-in short a situational-story. What could happen if all those things never did happen? What will happen to the Detective Boys 19 years later?
