Crime Stories: From the Files of Martin Mystere Message Board  

Can someone please help me figure out what the next move is? I am in the professor's house/castle whatever. Have looked all over except where the tape is blocking and rooms are locked. What do I do to move to the next level? I am going to throw this thing out the door if I don't move on finally-I have spent two weeks trying to figure it out! I have lots of tools but nothing seems to work and Java is reading the paper and is of no help. They are still questioning the housekeeper and Diana is still mysteriously unavailable by phone. WHAT? I've tried to get him to pick everything up but he won't. I saw a package in the housekeeper's room but can't move the chest to get it out and the guys downstairs won't finish dusting for prints. HELP!

Down stairs in the study on his desk on the right side of the room you will find a letter opener take that. In the housekeepers room under the bed is a box with key to open chest the key will break when you put it in the chest that when you will need the letter opener.
