Combine the Stove you found on the tray earlier with the Solid Fuel you just found in the cupboard to create a Stove that you can lit up.
Remember where the Painting B is located? Go back there and place the stove. Use the lighter to lit it up and the bugs surrounding the bottle with a corkscrew will vanish. Investigate the bottle and rotate it to get the Corkscrew.
Sadly, Marguerite will be alerted again and you have 30 seconds to put everything back in place again. Take the Stove again and put the Untitled Painting B back in its place. Place the Lantern on the wall and climb into bed and select wait to put the restraint on.
Once Marguerite leaves the room again, check the wall where you found the lantern. Use the Corkscrew you found to get the Lantern Hook. Get the other Lantern Hook in the far end of the Storage Room by using the Corkscrew again.
Combine the 2 Lantern Hooks to create an Iron Statuette.
Just behind the drawer where you got your Lighter, you’ll find a Knife. Get it.
Use the Knife you just found in the box wrapped in red tape inside the Storage Room.
Once the box is open, place the Lantern inside.
You’ll find a two plinths in the Storage Room that will be used for the Medusa and the Serpent shadow puzzle. Use the Iron Statuette on the one closest to the painting and rotate it until it resembles a Medusa. Next, use the Fork on the one closest to the light source box and make a Serpent Head.
A bird cage will open near the painting where you can get the Snake Key. You’ll then hear Marguerite coming inside the bedroom.
Before you face her, make sure you to equip the Knife to stun her for a moment.
Quickly investigate the clock to open the secret door and use the Snake Key. As soon as it opens, jump in and escape. This will then finish the chapter.
