As I turned to descend the steps, my eye was startled by a glimpse of movement among the shrubs that decorated the Kendrick lawn. At first I thought it but a branch tossed by the wind; but an incautious movement revealed the figure of a man silhouetted against the faint illumination from a distant street-lamp, and I felt a momentary gratification that my precaution had been justified. I descended the flight of steps to the garden with assumed unconcern. Then, instead of following the second flight to the street, I turned, made a sudden spring on to the lawn, straight for the shrub behind which I had seen the man hide himself. It was but twenty-five feet away, and I reached it in an instant. No one was there. For a moment I thought my eyes must have deceived me. Then the rustle of a bush by the fence attracted my attention, and I made a dash for the spot. Before I could reach it a man rose from behind the bush, vaulted the fence, disappeared for a second of time, and then could be seen running swiftly down the street. There was an eight-foot drop from the garden to the sidewalk, but I made the leap in my turn without mishap, and was running in the wake of the flying night-hawk before I had time to draw breath. I soon gained upon him, and as I came nearer I could hear his hoarse gasps, as the unaccustomed pace told upon him. At the corner of Sacramento Street I was near enough to reach out and grasp him by the coat. He halted and turned. "What do you want?" he growled, and then struck at me with sudden movement. "Take that!" he cried, striking again as I tried to close with him, and I felt the shearing of cloth before a sharp blade. As I staggered back from the impact of the blow, my foot caught on the curb, the earth whirled about, the stone sidewalk gave me a thump alongside the head, and I witnessed a private meteoric display of unrivaled splendor. I was stunned for a minute, but collecting my wits I scrambled to my feet, cleared my eyes, and looked for the flying enemy. He was nowhere to be seen, and no sound of his footfalls came to my ear. Making sure that he had escaped, I turned to take stock of my injuries. I could find no wound, though a rent through my coat showed how near I had come to the end of all my adventures. A memorandum-book in my inside pocket had stopped the blade with which the spy had struck at me. Then I recovered from my daze enough to become aware that I was holding an overcoat that was none of mine. The enemy had slipped from the garment to secure his escape, and had left it in my hands. *CHAPTER II* *THE HOUSE OF BLAZES*
