The Emperor glanced back at me, and slackened his pace a little so that I came within arm's length of him. You may think that I had my hilt well to the front, and that I had a very good look at these two people who were approaching us.
The one was tall, remarkably so, and of very spare frame, while the other was rather below the usual height, and had a brisk, determined way of walking. They each wore black cloaks, which were slung right across their figures, and hung down upon one side, like the mantles of Murat's dragoons. They had flat black caps, like those I have since seen in Spain, which threw their faces into darkness, though I could see the gleam of their eyes from beneath them. With the moon behind them and their long black shadows walking in front, they were such figures as one might expect to meet at night near the Abbot's Beech. I can remember that they had a stealthy way of moving, and that as they approached, the moonshine formed two white diamonds between their legs and the legs of their shadows.
The Emperor had paused, and these two strangers came to a stand also within a few paces of us. I had drawn up close to my companion's elbow, so that the four of us were facing each other without a word spoken. My eyes were particularly fixed upon the taller one, because he was slightly the nearer to me, and I became certain as I watched him that he was in the last state of nervousness. His lean figure was quivering all over, and I heard a quick, thin panting like that of a tired dog. Suddenly one of them gave a short, hissing signal. The tall man bent his back and his knees like a diver about to spring, but before he could move, I had jumped with drawn sabre in front of him. At the same instant the smaller man bounded past me, and buried a long poniard in the Emperor's heart.
My God! the horror of that moment! It is a marvel that I did not drop dead myself. As in a dream, I saw the grey coat whirl convulsively round, and caught a glimpse in the moonlight of three inches of red point which jutted out from between the shoulders. Then down he fell with a dead man's gasp upon the grass, and the assassin, leaving his weapon buried in his victim, threw up both his hands and shrieked with joy. But I--I drove my sword through his midriff with such frantic force, that the mere blow of the hilt against the end of his breast-bone sent him six paces before he fell, and left my reeking blade ready for the other. I sprang round upon him with such a lust for blood upon me as I had never felt, and never have felt, in all my days. As I turned, a dagger flashed before my eyes, and I felt the cold wind of it pass my neck and the villain's wrist jar upon my shoulder. I shortened my sword, but he winced away from me, and an instant afterwards was in full flight, bounding like a deer across the glade in the moonlight.
But he was not to escape me thus. I knew that the murderer's poniard had done its work. Young as I was, I had seen enough of war to know a mortal blow. I paused but for an instant to touch the cold hand.
'Sire! Sire!' I cried, in an agony; and then as no sound came back and nothing moved, save an ever-widening dark circle in the moonlight, I knew that all was indeed over. I sprang madly to my feet, threw off my great-coat, and ran at the top of my speed after the remaining assassin.
Ah, how I blessed the wisdom which had caused me to come in shoes and gaiters! And the happy thought which had thrown off my coat. He could not get rid of his mantle, this wretch, or else he was too frightened to think of it. So it was that I gained upon him from the beginning. He must have been out of his wits, for he never tried to bury himself in the darker parts of the woods, but he flew on from glade to glade, until he came to the heath-land which leads up to the great Fontainebleau quarry. There I had him in full sight, and knew that he could not escape me. He ran well, it is true--ran as a coward runs when his life is the stake. But I ran as Destiny runs when it gets behind a man's heels.
