You walk back down the hall and put your ear on the door to hear.

    Still nothing.

    Your curiosity reeling, you throw open the door and look inside.

    But there's nothing.

    No Paula.  No Sarah.  No Milton.

    No bathtub, no toilet, nothing!

    It's a void.
    


    Step inside the void.

    Close the door, then open it again.

    Go up in the attic.
