15- When her lover turned and looked at her, and his eye met hers as she sat there, paler and whiter than anyone in the vast ocean of anxious faces about her, he saw, by that power of quick perception which is given to those whose souls are one, that she knew behind which door crouched the tiger, and behind which stood the lady. He had expected her to know it. He understood her nature, and his soul was assured that she would never rest until she had made plain to herself this thing, hidden to all other lookers-on, even to the king. The only hope for the youth in which there was any element of certainty was based upon the success of the princess in discovering this mystery; and the moment he looked upon her, he saw she had succeeded, as in his soul he knew she would succeed.
