Professor Layton receives a letter asking for help from Luke. The strange thing is that this letter is from 10 years in the future, and the Luke in question is not Professor Laytons young apprentice, but rather his older self. According to the future Luke, the London of the future has been brought to the brink of ruin by Professor Laytons future self, who is the head of the largest crime syndicate in town. It seems the only man who can save London and stop the evil Professor Layton of the future is Professor Layton himself.
