And I saw Anita Prince now as a dark-haired, black eyed little beauty, in feature resembling her brother very strongly. She presently finished her meal. She rose, with him after her. She was dressed in Earth fashion--white blouse and dark jacket, wide, knee-length trousers of gray, with a red sash her only touch of color. She went past me, flashed me her smile and nod. My heart was pounding. I answered her greeting, and met George Prince's casual gaze. He, too, smiled, as though to signify that his sister had told him of the service I had done her. Or was his smile an ironical memory of how he had eluded me this morning when I chased him? I gazed after his small, white-suited figure as he followed Anita from the salon. And thinking of her, I prayed that Carter and Halsey might be wrong. Whatever plotting against the Grantline Expedition might be going on, I hoped that George Prince was innocent of it. Yet I knew in my heart it was a futile hope. Prince had been that eavesdropper outside the helio-room. I could not really doubt it. But that his sister must be ignorant of what he was doing, I was sure. * * * * * My attention was brought suddenly back to the reality of our table. I heard Ob Hahn's silky voice: "We passed quite close to the moon last night, Mr. Dean." "Yes," said Snap. "We did, didn't we? Always do--it's a technical problem of the exigencies of interstellar navigation. Explain it to them, Gregg--you're an expert." I waved it away with a laugh. There was a brief silence. I could not help noticing Sir Arthur Coniston's queer look, and I think I have never seen so keen a glance as Rance Rankin shot at me. Were all these people aware of Grantline's treasure on the moon? It suddenly seemed so. I wished fervently at that instant that the ten days of this voyage were over and we were safely at Ferrok-Shahn. Captain Carter was absolutely right. Coming back we would have a cordon of interplanetary police aboard. Sir Arthur broke the awkward silence. "Magnificent sight, the moon, from so close a viewpoint--though I was too much afraid of pressure-sickness to be up to see it." * * * * * I had nearly finished my hasty meal when another incident shocked me. The two other passengers at our table came in and took their seats. A Martian girl and man. The girl had the seat at my left, with the man beside her. All Martians are tall. This girl was about my own height--that is, six feet, two inches. The man was seven feet or more. Both wore the Martian outer robe. The girl flung hers back. Her limbs were encased in pseudo-mail. She looked, as all Martians like to look, a very warlike Amazon. But she was a pretty girl. She smiled at me with a keen-eyed, direct gaze. "Mr. Dean said at breakfast that you were big and handsome. You are." They were brother and sister, these Martians. Snap introduced them as Set Miko and Setta Moa.[5]
