She glanced at the shapeless heap, and shuddered. Agravaine nodded. 'No wedding-bells for her,' he said, reverently. 'And I don't care. I did it to save you. But come! We are wasting time. Come! I will help you to escape.' A man who has been shut up for two days in a small room is seldom slow off the mark when a chance presents itself of taking exercise. Agravaine followed without a word, and together they crept down the dark staircase until they had reached the main hall. From somewhere in the distance came the rhythmic snores of scurvy knaves getting their eight hours. Softly Yvonne unbolted a small door, and, passing through it, Agravaine found himself looking up at the stars, while the great walls of the castle towered above him. 'Good-bye,' said Yvonne. There was a pause. For the first time Agravaine found himself examining the exact position of affairs. After his sojourn in the guarded room, freedom looked very good to him. But freedom meant parting from Yvonne. He looked at the sky and he looked at the castle walls, and he took a step back towards the door. 'I'm not so sure I want to go,' he said. 'Oh, fly! Fly, Sir Knight!' she cried. 'You don't understand,' said Agravaine. 'I don't want to seem to be saying anything that might be interpreted as in the least derogatory to your father in any way whatever, but without prejudice, surely he is just a plain, ordinary brigand? I mean it's only a question of a ransom? And I don't in the least object--' 'No, no, no.' Her voice trembled. 'He would ask no ransom.' 'Don't tell me he kidnaps people just as a hobby!' 'You don't understand. He--No, I cannot tell you. Fly!' 'What don't I understand?' She was silent. Then she began to speak rapidly. 'Very well. I will tell you. Listen. My father had six children, all daughters. We were poor. We had to stay buried in this out-of-the-way spot. We saw no one. It seemed impossible that any of us should ever marry. My father was in despair. Then he said, "If we cannot get to town, the town must come to us." So he sent my sister Yseult to Camelot to ask the king to let us have a knight to protect us against a giant with three heads. There was no giant, but she got the knight. It was Sir Sagramore. Perhaps you knew him?' Agravaine nodded. He began to see daylight. 'My sister Yseult was very beautiful. After the first day Sir Sagramore forgot all about the giant, and seemed to want to do nothing else except have Yseult show him how to play cat's cradle. They were married two months later, and my father sent my sister Elaine to Camelot to ask for a knight to protect us against a wild unicorn.' 'And who bit?' asked Agravaine, deeply interested. 'Sir Malibran of Devon. They were married within three weeks, and my father--I can't go on. You understand now.' 'I understand the main idea,' said Agravaine. 'But in my case--' 'You were to marry me,' said Yvonne. Her voice was quiet and cold, but she was quivering.
