The roar, like an undertow, pulled Emma back to the place she didn’t want to be. It was a noise she knew. What was it? She opened her eyes cautiously. It roared again and didn’t seem to be in her head, even though a lot of other things were. Terror all the way through, and a fog so dense she couldn’t figure out what had happened, or how long she’d been there. Her throat was dry, and hurt so much she thought he must have tried to strangle her. She couldn’t stop shivering, just couldn’t stop. He had left the light on. Now she saw the skylight in the ceiling. It had been covered with garbage bags and carefully taped around the edges so no light could get in. What else could she see? She lifted her head. He wasn’t sitting beside her. He wasn’t pacing around the room with the knife or the gun in his hand. He must really have gone. His face was empty and hard, like a robot’s. She shuddered. There was nothing remotely familiar about him. She still didn’t know who he was, or if she had ever known him.
