constructed, even as they are on Earth. I had no trouble, therefore, opening the window. I swung a leg up and was presently within the darkened room. I found the door I sought and entered cautiously. In this adjacent compartment I made a thorough search but I did not find what I primarily sought—namely the elusive reason for Langley’s visit to Phobos. It was in a metallic overnight bag that I did find something else which made my power pack hum so loudly that I was afraid of being heard. The thing which explained the strangeness of the pompous Senator’s attitude today—which explained, in short, many things, and caused my brain to race with new ideas. I put the thing in my chest container, and left as stealthily as I had come. There had been progress, but since I had not found what I hoped to find, I must now try my alternate plan. Two hours later I found the one I sought, and made sure that I was seen by him. Then I left Argon City by the South lock, furtively, as a thief, always glancing over my shoulder, and when I made certain that I was being followed, I went swiftly, and it was not long before I was clambering over the first heaps of debris at the edge of the Dumps. Once I thought I heard footsteps behind me, but when I looked back there was no one in sight. Just the tiny disk of Deimos peering over the sharp peak of the nearest ridge, the black velvet sky outlining the curvature of this airless moon. Presently I was in sight of home, the time-eaten hull of an ancient star freighter resting near the top of a heap of junked equipment from some old strip mining operation. It would never rise again, but its shell remained strong enough to shelter my distillery and scant furnishings from any chance meteorite that might fall. I greeted it with the usual warmth of feeling which one has for the safe and the familiar. I stumbled over tin fuel cans, wires and other tangled metal in my haste to get there. It was just as I had left it. The heating element under the network of coils and pressure chambers still glowed with white heat, and the Moon Glow was dripping with musical sound into the retort. I felt good. No one ever bothered me here. This was my fortress, with all that I cared for inside. My tools, my work, my micro-library. And yet I had deliberately— Something—a heavy foot—clanked upon the first step of the manport through which I had entered.
