NiBiRu Hints
How do I open the iron cover in the study?
1 of 15: The opening in the outside of the iron cover would indicate that a key is needed.
2 of 15: Look around the study carefully for a clue as to where to find the appropriate key.
3 of 15: Take the journal from the desk and read it (you'll need to right-click on it from inside the inventory).
4 of 15: The final page states that the key to the safe was dropped down the drain.
5 of 15: The drain isn't in this room -- it's in another room in the tunnels.
10 of 15: The magnet by itself won't be very helpful. You'll need to figure out how to get it under the grate and back out again.
11 of 15: It is a "strange magnet". Try looking at it in your inventory.
12 of 15: The hole in the middle of the magnet could be helpful...
13 of 15: ... to tie it to a string. You should still have some string in your inventory (that was taken from the toolbox earlier).
14 of 15: Once you have tied the magnet to the string, you can use the "magnet on a string" on the grate to retrieve the key. Note: If you've done everything described, but you cannot use the "magnet on a string", be sure to look at the drain first (with nothing else in hand).
15 of 15: Use the key on the iron cover to reveal a safe inside.
