"I found this in the leader's room. It was tapped under the cupboard so suspiciously so I picked it up" knocking that wooden cupboard in the leader's room had not only opened his eyes to the paper tapped to the bottom but also to the moveable floor and that was how they found the hidden cabinet in the room. Then he could not say anything about the paper since the victims remains were more important so he just kept it till they were back. Now that they finally had the time to look through what had could possibly be in the papers, he brought it up. As he said, he walked to the center and placed the paper on the table.
Curious they gathered to see what it was. On the paper was a bunch of drooled pencil stroke. It looked like a diagram sketch but one that obviously was done by an amateur or perhaps in a hurry.
