She came up the incline with the carrier ahead of her. Gazing up, she saw Dr. Frank and me at the turret window, smiled and waved her white arm in greeting.

Dr. Frank laughed. "By the gods of the airways, there's Alta Venza! You saw that look, Gregg? That was for me, not you."

"Reasonable enough," I retorted. "But I doubt it—the Venza is nothing if not impartial."

I wondered what could be taking Venza now to Mars. I was glad to see her. She was diverting. Educated. Well traveled. Spoke English with a colloquial, theatrical manner more characteristic of Greater New York than of Venus. And for all her light banter, I would rather put my trust in her than any Venus girl I had ever met.

The hum of the departing siren was sounding. Friends and relatives of the passengers were crowding the exit incline. The deck was clearing. I had not seen George Prince come aboard. And then I thought I saw him down on the landing stage, just arrived from a private tube car. A small, slight figure. The customs men were around him. I could only see his head and shoulders. Pale, girlishly handsome face; long, black hair to the base of his neck. He was bare-headed, with the hood of his traveling cloak pushed back.

I stared, and I saw that Dr. Frank was also gazing down. But neither of us spoke.

Then I said upon impulse, "Suppose we go down to the deck, Doctor?"

He acquiesced. We descended to the lower room of the turret and clambered down the spider ladder to the upper deck level. The head of the arriving incline was near us. Preceded by two carriers who were littered with hand luggage, George Prince was coming up the incline. He was closer now. I recognized him from the type we had seen in Halsey's office.

And then, with a shock, I saw it was not so. This was a girl coming aboard. An arc light over the incline showed her clearly when she was half way up. A girl with her hood pushed back; her face framed in thick black hair. I saw now it was not a man's cut of hair; but long braids coiled up under the dangling hood.

Dr. Frank must have remarked my amazed expression. "Little beauty, isn't she?"
