They stumbled over the doorsill, the strong sunlight blinding their eyes after the darkness of the windmill interior. So it happened that none of them saw Warren till he was close to them. "Rosemary!" he cried in quick alarm. "Is anything the matter? You're as white as a sheet!" Rosemary tried to smile, but she swayed as she stood. He put an arm around her and led her to an overturned tomato crate under a tree. "Sit down," he said commandingly. "Do you feel faint?" "I'm not!" Indignation sent the color flying back to Rosemary's cheeks. "I'm never faint." But to her disgust, she began to tremble uncontrollably. She shook from head to foot and her lips were blue. "I was afraid!" she whispered. "So afraid--" and then she could have bitten her tongue. Sarah and Shirley were dismayed--never had they seen Rosemary like this. They crept close to her and she leaned her head against Sarah, closing her eyes. All the horror of the dizzy climb and descent pressed in upon her, tenfold stronger. Warren's quick eyes went from face to face. All three were white and strained. Plainly something had happened. Sarah and Shirley had torn their dresses and there were great dust and oil stains on Rosemary's white skirt. Warren wheeled and looked back. The windmill door swung slowly in the breeze. "Rosemary!" he spoke so sharply that she jumped. "Rosemary, have you been in the windmill? Have you been hurt?" CHAPTER XXVI SOMETHING TO REMEMBER Warren stood a moment in indecision. Rosemary's pallor frightened him and she was evidently concealing something. Sarah and Shirley glanced at him hostilely as though, he thought resentfully, he was in some way to blame. He turned on his heel and ran over to the mill, shutting the door with a resounding slam. In a trice he had snapped the padlock and had come back to the three girls huddled under the tree. And then a cheerful whistle sounded and down the lane came the one person Rosemary least desired to see at that moment--Doctor Hugh. "Got through early!" he called, vaulting the fence and striding toward them. "Why, Rosemary! What's wrong?" Rosemary made a desperate effort to recover her self-control. She managed a shaky smile, but she did not dare try to stand. "Perhaps you can find out," said Warren grimly. "I found her like this a few minutes ago and Shirley and Sarah looking as though they'd seen a ghost; and not a word will any of 'em say." Very coolly, very quietly, very firmly, Doctor Hugh lifted Sarah aside and took her place beside Rosemary on the crate. He rested the tips of his fingers for a moment on the slender wrist nearest him. Then-- "What frightened you. Rosemary?" he asked evenly.
