Go down to the hallway at the bottom floor of the hotel. You will see the ghost that walks through into a wall. Move to a dead plant in the corner of the hallway near to a locked door. Then, go back towards the hallway where you saw the ghost. Make sure you have your Fibre Wire out before continuing. Heading down the corridor, you will see the ghost who walks into the wall. Get your Fibre Wire ready then get behind the ghost before it disappears into the wall. If you are quick, you can strangle the ghost with your Fibre Wire, which now flickers on the ground. You can now drag the ghost around the hotel.
