First part: You have to go back to the butler's room I believe and you have to get the
doll that plays the drums. Then you have to find the key for it which is in the library.
To find the clue to where the key is you have to look at that weird picture sitting on the
table in the library then fold your DS down until you see the reflection it should say F3.
Then you have to go over to the book shelf and find the F and look on the third shelf.
It's in one of those books. Then when you have both of those go back to the music box. Put
the doll in the box, use the key... you have to turn it... then press the flute, the horn
and the drums! voila!

when u do that they hear a noise and in another room it opens the fire and jessica is in
that room
you see a painting that used to be on the wall and you blow the dust of that
and on the box is two pics
write down the candle pics and take the matches and go to the door and light the candles
to one of the pics
