... This is how I plunged into a series of dangerous adventures, a dark underworld of crime and almost superhuman cunning, probably without parallel in modern times. Arrangements were soon made at Whitehall. Muir Lockhart was an understanding man, and by three o'clock in the afternoon I walked out into the sunshine free from all official cares for a month. I took a long, deep breath as I crossed the Horse Guards Parade and made my way to the long, green vista of the Mall. "The first act is over," I thought. "The curtain is rising on the real drama. Somewhere in this world there is a man whose discovery and death I owe to Society and to myself." And I was a man who never failed to pay a debt. I have given you but little indication of my mental state during the last few days. It won't bear much writing about even now. A cold fury, instead of blood, came and went in my veins, and my heart was ice. Every now and again, especially when I was alone, agony for which there is, there can be, no name got hold of me, and sported with me as the wind sports with a leaf. I suppose I had a tiny foretaste of what is felt by a soul that is eternally damned. I _dared_ not think too much of Constance and her fate. If I had let myself go that way the running waters would have risen and overwhelmed me utterly. But, thank God, my intellect held. The streak of hardness which had served me so well in my career, and had enabled me to push to the top at an early age, came to the rescue now. Every faculty was sharpened; the will concentrated to a single purpose. I was alone, and I walked in darkness, but I was conscious of Power--charged to the brim as a battery is charged with the electric fluid. As I walked calmly up St. James', on the way to my chambers, I doubt if a more single-minded and dangerous man than I walked the streets of London. And I knew, by some mysterious intuition, that I should succeed in the task before me. I had not, as yet, more than the most rudimentary idea how I was going to set about it, but I should succeed. Don't misunderstand me. I had hardly any hope of seeing my dear love alive again. I believed that all the joy of life was finally extinguished. But justice--call it vengeance rather--remained, and I was as sure that I was the chosen instrument of that as I was that I had just passed between Marlborough House and the Palace of St. James. My expensive but delightful chambers in Half Moon Street were on the second floor--sitting-room, dining-room, bed and dressing rooms and bath. The sitting-room was panelled in cedar-wood, which had been stained a delicate olive-green, with the mouldings of the panels picked out in dull gold. Connie and her gay young friends, when they came to have tea with me, or supper after the theatre, used to say that it was one of the most charming rooms in London.
