Professor Layton and the Diabolical Box (JP) (Professor Layton and Pandora's Box in Europe & Australia) is the successor to the Nintendo DS video game Professor Layton and the Curious Village. The game was initially released in 2007 by Level 5 and then released in 2009 in America and PAL regions. It is set after Professor Layton and the Curious Village, when Professor Layton receives a letter from his old mentor, only to go to his house and find him dead. The culprit is supposed to be a box that curses anyone who opens it, and the only clue is a ticket for the Molentary Express.
