Walkthrough
In the top floor bedroom, there is a little housing unit around the top of the stairs. On top of that housing, all the way against the west wall, there in a "Long Forgotten Note". You can reach it without any furniture by getting in the corner between its North wall and the Bedroom's West wall, jumping straight up, and grabbing the note from the corner. Another way to get it with furniture is to jump of the nearby table, then onto the bookshelves, the just grab the note (it will be at eye level). This note gives a riddle, the answer to the riddle is a hourglass. In the basement there is a pillar with garlic hung on the sides of it. Where the pillar meets the ceiling there are a few connecting planks running diagonally. Between one of the planks and the pillar is an hourglass, take it.
