But the horse was old and the man had a sort of instinct about him. We got on all right till we were more than half way to our journey's end. The road was straight and the moonlight bright, especially after we had passed a certain corner, and got well out of the shade of the trees which skirted the first part of the way. Just past this turn there came a dip in the road. It went down, down gradually, for a quarter of a mile or more, and I looked up anxiously, fearful of the horse taking advantage of the slope. But no, he jogged on, if possible more slowly than before, though new terrors assailed me when I saw that the driver was now fast asleep, his head swaying from side to side with extraordinary regularity. After a bit I grew easier again; he seemed to keep his equilibrium, and I looked out at the side window on the moon-flooded landscape, with some interest. I had never seen brighter moonlight. Suddenly from out of the intense stillness and loneliness a figure, a human figure, became visible. It was that of a man, a young and active man, running along the footpath a few feet to our left, apparently from some whim, keeping pace with the fly. My first feeling was of satisfaction that I was no longer alone, at the tender mercies of my stupefied charioteer. But, as I gazed, a slight misgiving came over me. Who could it be running along this lonely road so late, and what was his motive in keeping up with us so steadily. It almost seemed as if he had been waiting for us, yet that, of course, was impossible. He was not very highwayman-like certainly; he was well-dressed--neatly-dressed that is to say, like a superior gamekeeper--his figure was remarkably good, tall and slight, and he ran gracefully. But there was something queer about him, and suddenly the curiosity that had mingled in my observation of him was entirely submerged in alarm, when I saw that, as he ran, he was slowly but steadily drawing nearer and nearer to the fly. "In another moment he will be opening the door and jumping in," I thought, and I glanced before me only to see that the driver was more hopelessly asleep than before; there was no chance of his hearing if I called out. And get out I could not without attracting the strange runner's attention, for as ill-luck would have it, the window was drawn up on the right side, and I could not open the door without rattling the glass. While, worse and worse, the left hand window was down! Even that slight protection wanting!
