You must follow the lead.
Look around in the room. On the wall is a note. Take the NOTE and look at the note in your inventory. Use the door north to get to the next room and find Amber on the floor. Apparently it was a setup. Now that you’re trapped, you need to find a way out of the house.
Look around the hall again and read the sign on the wall. Use the door north to return to Amber and talk to her. Ask her how to get out and she’ll tell you about the secret passage. But the only thing she tells you is ‘William’. Then she stops responding.
Use the door on the right and in the hall use the stairs to go to the top floor. Use the door on the right to enter the library and look at all the books. There’s one on the second shelf from the bottom, third cabinet from the right. It’s the selected works of W. Shakespeare. That’s a William! Take the BOOK and look at it in your inventory.
While going through the book, a piece of PAPER falls out and looking at the paper, you see a map of some kind with a line and words written on it. Walk to the left to leave the library and back in the hall you’ll hear a scream from Amber. Walk to the lower right to go down the stairs. Go to the left to return to Amber. But she’s gone. Look at the blood on the floor and the text on the wall.
Walk south and to the right into the dining room. There are statues of Greek gods on the desk on the left. Touch the statues to have a closer look. In front of the statues are buttons in the desk. You need to push them in the correct order.
Leave the statues and walk south to leave the dining room. Use the door north to return to where Amber was and go to the right to enter the hall. Use the stairs to go up and use the door on the right to return to the library. To the right and one shelf higher is a book about mythology. Take the BOOK and look at the book in your inventory. Read all about the Greek gods and learn their Roman equivalent names.
Walk to the left to leave the library and in the corridor walk to the lower right to go down the stairs. Walk left into the living room, south to the hall and use the door on the right into the dining room. Use the small statues again. Use the text you saw earlier on the wall: damn v to determine the order. d=diana=artemis, a=apollo=apollo, m=mercury=hermes, n=neptune=poseidon and v=venus=aphrodite. So number the statues from left to right from 1 to five and press the order 3, 4, 2, 5 and 1. You won’t see any buttons move but after the right sequence you’ll hear a rattling sound.
Use the cabinet under the figurines to find a KEY and take it out. Walk south to leave the dining room and to the left into the hall. Another sound. Use the door north to the lounge and go to the right to the staircase. Climb the stairs and use the key on the first door on the left to unlock it. Use the door to enter the bedroom.
Now quickly take the BABY OIL from the cabinet on the left and use the oil on the latch of the door you just entered. Quickly slide the latch to bolt the door. The Stranger is not able to enter the room now. Pick up the DIARY from the bedside cabinet and read it. After reading, use the door to leave the room. Find a shard of GLASS on the floor. Pick it up and use the door next to the bedroom on the left and look around the room.
On the wall is a colorful tapestry. Use the glass to cut the tapestry and reveal a safe behind it. Use the safe to find that you need a six digit code. The only numbers we know are from the diary. One entry was about Amber’s mothers birthday the next day. So calculate the birthday and enter 061644. You take the LOCKET and a piece of PAPER out. In your inventory combine the two pieces of paper and look at them. It’s a map. Take the pen from your inventory and use it on the map to make the lines meet.
The lines point to the dining room. Walk to the right to enter the corridor and go to the lower right to go down the stairs. Walk left into the dining room, south to the hall and use the door on the right to enter the dining room. Look at the head of the moose. Use the head to make the eye pop out. Look at the head again to find the mechanism. Now only to find something that fits in there.
In your inventory look at the locket to see the amethyst at the front. Use the glass shard to pry to STONE from the locket. Use the amethyst on the mechanism in the head of the moose and open the secret passage. You’re free.
