"I beat your wondering how I got my hands on the one person who knows all."he reached into the cage and yanked Katherin's hair. "My pretty patient's demon has a secret of his own. Something she didnt even know. Her demon use to be in love with mine. Making her venerable to me. So he warned her to late that I was behind her."
