Miss Norton, Miss Parker, and Miss Broadway had specially reserved chairs in the front row, and the girls filled up the rest of the room. Some of them, to obtain a better view, squatted on the floor in front of the chairs, Chrissie and Marjorie being among the number. The lantern worked beautifully; Patricia made a capital little operator, and managed to focus very clearly. She first of all showed sets of bought slides, scenes from Italy and Switzerland and photos of various regiments, and when these were finished she turned to the slides which she and her chums had made themselves. There were capital pictures of the school, the cricket eleven, the hockey team, the quadrangle in the snow, the gardening assistants, and the tennis champions. They were received with much applause, Miss Norton in particular congratulating the amateur photographers on their successful efforts. "We haven't had time to do very many," said Patricia, "but I've got just a few more here. This is a good clear one, and interesting too." The picture which she now threw on the screen showed the road leading to Whitecliffe, up which a contingent of German prisoners appeared, guarded by soldiers. In the foreground was a long perambulator holding a little boy propped up with pillows. It was an excellent photograph, for the contingent had been caught just at the right moment as it faced the camera; both prisoners and guards had come out with remarkable clearness. Something impelled Marjorie to glance at Miss Norton. The house mistress was gazing at the picture with an expression of amazed horror in her eyes. She turned quickly to Irene, who was squatting at her feet, and asked: "Who took that photo?" "Marjorie Anderson took it, but I made the lantern slide from her film," answered Irene proudly. "We think it's quite one of the best." "I suppose it was just a snapshot as she stood by the roadside?" "Yes; it was a very lucky one, wasn't it?" Marjorie, sitting close by, nudged Chrissie, but did not speak. Miss Norton made no further remark, and Patricia put on the next slide. Afterwards, in the corridor, Marjorie whispered excitedly to Chrissie: "Did you notice Norty's face? She was quite upset by my photo of the German prisoners." "Yes, I noticed her." "Significant, wasn't it?" "Rather!" "It's like the play scene in _Hamlet_. It seems to me she gave herself away." "She was taken unawares." "Just as the King and Queen were. You remember how Hamlet watched them all the time? What's happened to-night only confirms our suspicions." "It does indeed!" "Perhaps some of her German friends were among the prisoners and she recognized them." "It's possible." "Well, it evidently gave her a great shock, and that would account for it." "The plot thickens!" "It thickens very much indeed. I'm not sure if we oughtn't to tell somebody." "No, no! Not on any account!" "You think so?" "I'm certain of it. You'll spoil everything if you go blabbing!"
