Zack was confused by the fox's behavior. He had never seen anything like it. He didn't know what to say or do. He nodded. He continued following the scent trail. He didn't know where it was leading but he would follow it. He hoped that the fox would be alright. He stopped in front of a bookcase. He frowned. The trail stopped here. It didn't make any sense. He check to the right and to the left.
