"Mr. Ducaine," he said, "you must see for yourself that I am running a very serious risk in making these plans with you behind the backs of the Duke of Rowchester and Colonel Ray. The Duke is a man of the keenest sense of honour, as his recent commercial transactions have shown. He has parted with a hundred thousand pounds rather than that the shadow of a stigma should rest upon his name. He is also my personal friend, and very sensitive of any advice or criticism. Then Ray--a V.C., and one of the most popular soldiers in England to-day--he also is quick tempered, and he also is my friend. You can see for yourself that in acting as I am, behind the backs of these men, I am laying myself open to very grave trouble. Yet I see no alternative. There is a rank traitor either on the Military Board or closely connected with the Duke's household. He does not know it, nor do they know it, but everyone of his servants has been vigorously and zealously watched without avail. The circle has been drawn closer and closer, Mr. Ducaine. Down in Braster you may be able to help me in narrowing it down till only one person is within it. Listen!" Lady Chelsford entered, gorgeous in white satin and a flaming tiara. She looked at me, I thought, a little gravely. "Morton," she said, "I want you to spare me a minute. Mr. Ducaine will excuse you, I am sure." Lord Chelsford and she left the room together. I, feeling the heat of the apartment, walked to the window, and raising the sash looked out into the cool dark evening. At the door, drawn up in front of Lord Chelsford's brougham, was a carriage with a tall footman standing facing me. I recognized him and the liveries in a moment. It was the Rowchester carriage. Some one from Rowchester House was even now with Lord and Lady Chelsford. Fresh complications, then! Had the Duke come to see me off, or had his suspicions been aroused? Was he even now insisting upon an explanation with Lord Chelsford? The minutes passed, and I began to get restless and anxious. Then the door opened, and Lord Chelsford entered alone. He came over at once to my side. He was looking perplexed and a little annoyed. "Ducaine," he said, "Lady Angela Harberly is here." I started, and I suppose my face betrayed me. "Lady Angela--here?" "And she wishes to see you," he continued. "Lady Chelsford is chaperoning her to-night to Suffolk House, but she says that she should have come here in any case. She believes that you are going to China." "Did you tell her?" I asked. "I have told her nothing," he answered. "The question is, what you are to tell her. I understand, Ducaine, that Lady Angela was engaged to be married to Colonel Ray." "I believe that she is," I admitted. "Then I do not understand her desire to see you," Lord Chelsford said. "The Duke of Rowchester is my friend and relative, Ducaine, and I do not see how I can permit this interview."
