Professor Layton is Back with a Puzzling Prequel This fourth installment of the Professor Layton puzzle adventure series begins a new trilogy that is a prequel to the original games. Three years before the events in the Professor Layton and the Curious Village game, Professor Layton receives a letter from his old schoolmate Clark, telling him that "a mysterious giant is destroying the town." The professor heads to the town of Misthallery to investigate, and is joined by Emmy, his new assistant. What is the meaning of all the destruction, and is it related to the village's folklore legend of a "specter"? The unfolding story details how Professor Layton and his apprentice, Luke, met.
