In the first game, Layton was interested in finding the Golden Apple, a treasure owned by the king of the town of Saint Mystere, a curious little village where all the people are quirky and there is a strange tower built in the back of the town. After solving several puzzles, Layton sees a man running through the town, carrying a large bag with a head coming out of it, he races after him but fails to catch him. The day after that, they meet Inspector Chelmey, a man who was hired to solve the death of the man who's head was coming out of the bag. After doing a bit of searching, they see a suspicious girl, they chase her, and are lead to the large tower, upon solving several puzzles, they get to the top, and, oh yeah, I forgot to say that everyone in the town is mechanical. The golden apple is really the kings daughter, but the real treasure is found later. She finds a note that says "When the treasure is removed, everyone in the town will, just, die. She became so attached to them that she leaves the treasure there. Layton then adopts her, at the request of the king's letter, and the story is open for the sequel.
