Diana is much taller and stronger than I am. She could take the coat from me by force; and the thought darted through my head that without it to prove where and how the lost message had been found, the paper would lose half its value. My word, unsupported by proof, would not be enough against Major Vandyke, for it was known that I detested him, and was a sworn friend to Captain March. I must keep the coat at any cost to myself--or even to Diana. Standing at bay, looking up at her white face of anger and suspicion, I felt very small and frail of body; but my soul gathered strength of battle. I clasped my bare arms over the coat and locked my fingers round my two elbows. "This is mine," I said. "You gave it to me to do as I liked with. You've no right to take it away. I'm going to make a present of it to somebody who's been robbed of everything, and needs it." This was the best explanation I could think of. But it was not good enough for Diana. She attempted to push me farther back, and I resisted, trying to wriggle myself free and elude her; but she was on the alert, and too quick as well as too strong for my trick to succeed. "No, you shan't slip away like that, you little wild-cat!" she cried, beginning to pant slightly. In the white light of the electric candelabra, which made the corridor bright as day, I saw her beautiful bosom heave under its double rope of creamy pearls. All the charming softness which men loved was gone from her face. It looked hard and cruel. Just as I meant to escape at any price, so she meant at any price to keep me. I guessed that she had come home alone, and let herself in with a latch-key, for apparently there were no servants about. That was fortunate for me; and fortunate that Father and Kitty, and above all Sidney, had gone on somewhere else from the Russian Embassy, for there would have been very little chance for me if I had had to run the gauntlet. "You hate Sidney. I believe you hate me, too!" she went on when she had got her breath. "I don't trust anything you say or do. You've some horrid idea in your head. I read that in your face the instant I saw you here. You mean mischief. What's in your mind I don't know, but I _shall_ know! You'd better tell me!" "I've told you all I have to tell," I said. "If I'm a wild-cat, you're a tigress. What will the servants think if they come and see you like this?" "I don't care what they think. And besides, they won't come. I've changed my mind about giving you that coat. I must ask Sidney first if he wants to keep it for any reason. I'll let you know to-morrow." "To-morrow will be too late. I've to see my man to-night." "Why are you taking him the coat, and not the rest of the suit?" she persisted. "It's only the coat that will be of use to him." I had the answer ready.
