Cooper was watching him. “It’s probably nothing,” Brian muttered. He pressed play. At first there was only a rough layer of static, low and fuzzy. Then something pushed through it. Brian froze. A low sound dragged out of the speaker, deep and uneven, not quite a groan and not quite anything he could name. It didn’t sound human. It didn’t sound like music either.
It sounded wrong. Behind it came a slow, hollow thudding, spaced far enough apart to make each one land on its own. Brian stared at the player. The sound dipped lower, then rose again in a long scraping pull that made his skin tighten.
