"I want Zanda again," I said. "She performs her duties satisfactorily, and I prefer her."

"That is something you will have to discuss with Fal Sivas," he replied.

I passed out then into the night and gave the matter no further thought, my mind being occupied with far more important considerations.

My way led past the public house where I had left Jat Or and on into another quarter of the city. Here, without difficulty, I located the building that Fal Sivas had described.

At one side of it was a dark narrow alley. I entered this and groped my way to the far end, where I found a low wall, as Fal Sivas had explained that I would.

I paused there a moment and listened intently, but no sound came from the interior of the building. Then I vaulted easily to the top of the wall, and from there to the roof of a low annex. Across this roof appeared the end of the hangar in which Gar Nal had built his ship. I recognized it for what it was by the great doors set in the wall.

Fal Sivas had told me that through the crack between the two doors, I could see the interior of the hangar and quickly determine if the ship were still there.

But there was no light within; the hangar was completely dark, and I could see nothing as I glued an eye to the crack.

I attempted to move the doors, but they were securely locked. Then I moved cautiously along the wall in search of another opening.

About forty feet to the right of the doors, I discovered a small window some ten feet above the roof upon which I was standing. I sprang up to it and grasped the sill with my fingers and drew myself up in the hope that I might be able to see something from this vantage point.

To my surprise and delight, I found the window open. All was quiet inside the hangar—quiet and as dark as Erebus.

Sitting on the sill, I swung my legs through the window, turned over on my belly, and lowered myself into the interior of the hangar; then I let go of the sill and dropped.

Such a maneuver, naturally, is fraught with danger, as one never knows upon what he may alight.

I alighted upon a moveable bench, loaded with metal parts and tools. My weight upset it, and it crashed to the floor with a terrific din.

Scrambling to my feet, I stood there in the darkness waiting, listening. If there were anyone anywhere in the building, large as it appeared to be, it seemed unlikely that the racket I had made could pass unnoticed, nor did it.

Presently I heard footsteps. They seemed at a considerable distance, but they approached rapidly at first and then more slowly. Whoever was coming appeared to grow more cautious as he neared the hangar.

Presently a door at the far end was thrown open, and I saw two armed men silhouetted against the light of the room beyond.
