Diana said nothing more, but as she went on with her wreath her thoughts were as busy as her fingers. She was more silent than usual at lunch, and slipped away quickly afterwards, leaving the family talking round the fire. First, she ran upstairs to the corner of the upper landing, where she knew the big Union Jack was kept. She rolled it into a tight bundle, tucked it under her arm, then tore off to the church. She found herself alone there, for none of the other decorators had returned. It was exactly the opportunity she wanted. The bunch of keys was hanging in the big door. She pulled them out, and carried them to the tiny door by the chancel steps. This she unlocked and flung open, disclosing a steep, winding stair. Almost on her hands and knees Diana scrambled up, and up, and up till she reached the triforium, the narrow stone gallery that ran round the church under the clerestory windows. The first few yards were safely protected with arches, pillars, and a balustrade, but after that came a stretch of about twenty feet with no parapet at all. The gallery was only twenty-four inches wide; on the one side was the wall, on the other a sheer drop of about thirty feet. Diana paused, and set her teeth. She did not dare to walk it, but she knelt down and crawled along till she reached the next piece of balustrade. Then she unrolled her Union Jack, and, tying it by its cords to the pillars, arranged it so that it hung down into the church and covered the exact spot of blank wall that Monty had indicated. She had just finished when she heard footsteps in the porch. Not wanting to be caught by the Vicar, she began to crawl back in the same way as she had come. Perhaps the sense that someone might be watching her from below unnerved her, for the return journey seemed far worse than the outward one had done. She did not venture to look down, but kept her eyes on the wall. Half-way she was suddenly seized with a horrible paroxysm of dizziness. For a moment or two she lay flat, too frightened to move, while her giddy head seemed to be spinning round. With a supreme effort she mastered the sensation, and crawled on, inch by inch, till she once again reached safety. With rather tottering knees she came down the winding staircase, and through the small door to the chancel steps. Mrs. Fleming, Meg, Monty, and Neale were standing by the lectern when she appeared. Mrs. Fleming was white as chalk; the others were staring open-mouthed, with a queer strained look in their eyes. "Well, I've done it, you see!" said Diana jauntily. The Flemings gazed at her without speaking. Monty went and locked the door of the staircase and put the keys in his pocket. The silence was embarrassing. "I think it looks very nice hanging there," declared Diana, nodding at her Union Jack.
