'Beatrice didn't lie,' Mathew thought as he climbed past the middling floors and all the way up to the top of the school's wing that his group inhabited.
There were only two or three people in total on the top floor. Mathew saw them through the hole in the wall leading to the room that used to serve as a toilet. They all wore masks on their faces made from some cloth folded several times over and had even more cloth wrapped around their hands.
And their job was fairly simple. They would go into the room with huge bags and shovels and fill the bags with all the filth inside before throwing them down the class window.
Out of curiosity and while waiting for Nadia to return with the rest of the used blades, Mathew approached another window and took a look outside.
The area below the dumping window used to be just another part of the grass-covered courtyard with a single strand of the concrete path going straight across.
