” Professor Layton and the Diabolical Box – Molentary Express ” is Professor Layton’s third game, which was originally released in 2009 by Level-5 Inc. for Nintendo DS.
The Professor’s next destination is London, where he boards the Molentary Express, along with Luke Triton and Emmy Altava; but while on their way to the real-life town of York, Professor Layton and his assistant meet a girl named Flora Reinhold.
Flora has lost an item she cherishes very much – her father’s music box – which is said to be made out of gold. Professor Layton is intrigued by this story, for golden music boxes are supposedly made to never play music.
To Professor Layton’s surprise, the train is then destroyed by an explosion caused by a mysterious man who calls himself Don Paolo. Professor Layton and Luke are saved from almost certain death because of Emmy, who has the ability to predict natural disasters . With this power in mind, Professor Layton sets off with Emmy and Luke to find Professor Layton’s newest friend, Flora.
After Professor Layton saves the group from a collapsing bridge on the way to York (which Don Paolo had destroyed), Professor Layton and company finally arrive at Professor Layton’s destination: Professor Layton and the Azran Legacy .
