To Snap and me, the glories of the heavens were too familiar to be remarked. And upon this voyage particularly we were in no mood to consider them. I had been in the radio room several hours. When the Planetara started, and my few routine duties were over, I could think of nothing save Halsey's and Carter's admonition: "Be on your guard. And particularly—watch George Prince."

I had not seen George Prince. But I had seen his sister, whom Carter and Halsey had not bothered to mention. My heart was still pounding with the memory.

Dr. Frank evidently was having little trouble with pressure sick passengers. The Planetara's equalizers were fairly efficient. Prowling through the silent metal lounges and passages, I went to the door of A22. It was on the deck level, in a tiny transverse passage just off the main lounging room. Its name-grid glowed with the letters: Anita Prince. I stood in my short white trousers and white silk shirt, like a cabin steward staring. Anita Prince! I had never heard the name until this night. But there was magic music in it now, as I murmured it.

She was here, doubtless asleep, behind this small metal door. It seemed as though that little oval grid were the gateway to a fairyland of my dreams.

I turned away. Thought of the Grantline Moon Expedition stabbed at me. George Prince—Anita's brother—he whom I had been warned to watch. This renegade—associate of dubious Martians, plotting God knows what.

I saw, upon the adjoining door, A20, George Prince. I listened. In the humming stillness of the ship's interior there was no sound from these cabins. A20 was without windows, I knew. But Anita's room had a window and a door which gave upon the deck. I went through the lounge, out its arch and walked the deck length. The deck door and window of A22 were closed and dark.

The deck was dim with white starlight from the side ports. Chairs were here but they were all empty. From the bow windows of the arching dome a flood of moonlight threw long, slanting shadows down the deck. At the corner where the superstructure ended, I thought I saw a figure lurking as though watching me. I went that way, but it vanished.

I turned the corner, went the width of the ship to the other side. There was no one in sight save the observer on his spider bridge, high in the bow network, and the second officer, on duty on the turret balcony almost directly over me.

As I stood and listened, I suddenly heard footsteps. From the direction of the bow a figure came. Purser Johnson.

He greeted me. "Cooling off, Gregg?"
