Traces in the Dark
You decide to head over to the Principal's Office and inspect the broken window yourself. As you carefully examine the shattered glass, you notice something unusual: a small piece of dark fabric caught on a jagged edge of the window. It looks like it could be from a jacket—possibly the same one worn by the mysterious figure that Tom mentioned.
Near the window, you also find a trail of tiny glass shards leading to the back door, suggesting that the window was broken from the inside. This means whoever broke it must have been trying to get out of the building quickly.
With the fabric and this new information, you need to decide what to do next.
