"Oh, cruel!" she reproached me. "Was it _he_ who asked you not to tell, or was it your own thought?" "He?" I echoed. "You all talk in riddles. You accuse me of something, and won't explain what it is." "You _must_ know!" Di exclaimed. "But I can't talk about it now, or I shall break down again. Thanks for the champagne, Sid. You were right; it did me good. Now we'll go." She brushed past me in the corridor, her head turned away; and as I stared stupidly after her and Major Vandyke, suddenly my eyes fell on a small but conspicuous spot of red that marred the lustre of Di's silver train. It looked like a drop of blood. When the two had gone, I pounced upon Mrs. Main. "For pity's sake, explain the mystery!" "Oh, it was dreadful for a few minutes," she said. "There was nearly the most _awful_ accident. Of course you came out too late to see. But--you _do know who was in the church_?--at least, I suppose he must have been there." I started as if she had boxed my ears, for without telling, I knew all she meant. I remembered the odd feeling I had had of some one trying to call me, as if in a dream; and how I had looked behind me in vain. Tony, too, had been very strange. He had begun to say something and had stopped in haste. He had promised to explain later, but coming home I had forgotten to ask him. There had been the excitement about the supposed accident to Diana, and my thoughts had clung to that. Now I realized that there was only _one person_ who might have been at St. George's with my secret connivance, whose presence there Sidney Vandyke would furiously resent: Eagle March. Kitty was looking at me curiously, almost appealingly, and I was vexed with myself for blushing. "I do not know," I answered steadily. "I might guess--but almost surely I should guess wrong. Tell me who, in all that crowd, it was worth Sidney's while to make this fuss about." "Well," said Kitty, who being far from brave is easily abashed, "I'm not sure he _was_ inside the church, but anyhow he was _outside_, because I saw him the instant before he seized the horses' heads. And then----" "Seized the horses' heads? But who--who?" "Captain March. Of course it was he who saved Diana and Major Vandyke. At least I think he deserves so much credit, and Di would think it, too, if she were left to herself. But Major Vandyke says the whole thing was arranged; that it was Captain March who planned--to--to----" "He's sure to say something horrible. But begin at the beginning!" "I can't now, dear," said Kitty nervously. "Di and Sidney will be so cross if I stay up here talking to you. I really must go down; but you're sure to hear everything."
