Hears apartment

I made sure my shield bracelet was ready to go, and marched up to Anna's door. I could sense the ward there, still active, so I thumped my staff on the floor immediately in front of the door. "Ms. Ash?" I called. It wasn't like I was going to wake anyone up. "It's Harry Dresden. We need to talk."
There was silence. I repeated myself. I heard a sound, that of someone striving to move silently, a scuff or a creak so faint that I wasn't sure it had been real. I checked Mouse. His ears were pricked up, swiveled forward. He'd heard it too.
Someone flushed a toilet on the floor above us. I heard a door open and close, a faint sound, also on another floor. There was no further sound from Anna Ash's apartment.
