Reveal

The police officers from nearby have started to gather around the small building. They hauled the boxes off the room. 

The towering heavy boxes were removed from the wall it was leaning to, revealing the wooden wall that is completely different from the brick walls on the other side.

Shocks and murmurs floated from the crowd of police officers. Their faces looked grim, but their determined eyes continued. They work harder than ever. Carrying heavy junk boxes full of old and unused materials from the different sports in the school.

In the live feed, Diane have sense that her hiding place was revealed. But instead of wearing a worried expression, there was a weird smile on her face.

She glance at the timer that now have only eight minutes left. She flip her hair and adjusted her glasses. 

"Diane's sister, I'm sure you are puzzled why I sent you that letter... Or maybe you already have an idea. Hehe," then she giggled.
