Chapter 101 - In a Hurry

I pulled open the sliding door at the top of a staircase in the corner of the underground space, stepping out as I slid it open. There's a bookshelf on the other side of it, connected to the door. 

Talk about cliche, a hidden entrance behind a bookshelf...well, whatever. I'll just leave this open for the police to find. I certainly wouldn't mind letting them rot down there, but the corpses of the Alter victims they were torturing, they deserve proper burials. 

Hm? What's that sound? A high pitched noise is echoing out from outside...as I quietly walked towards the door of the room and opened it cautiously, the noise grew louder.

 

Those are...police sirens. The blast I used to burst through the floor, someone outside the building must have heard it and contacted the police. This is bad, I can hear the sirens ringing out from all around the building, they've got the place surrounded.
