There was a stretch where nothing else happened, long enough that Avery started to doubt himself. He fumbled with his phone, setting it to record, getting mostly dark grainy footage of the walls.
His breathing started to calm down, and he swallowed. "Maybe-" he started to say, and then a sudden cold gust whooshed through the broken window and blew out the candle, and there was an echo of what sounded like a drawn-out scream from below. Avery cried out in fright and turned to the door as it slammed shut, so he wrenched it open and fled to the stairs, almost forgetting Henry was there in his haste.
