Our attention focussed upon the other two. They were tall, as are all Martians. The young woman, _Setta_ Meka, seemed perhaps twenty or twenty-five years of age, by Earth reckoning, in stature perhaps very nearly my own height, which is six feet two. It is difficult to tell a Martian's age, but she was very handsome, even by Earth standards; and in Ferrok-Shahn she would be considered a beauty. Her gray-black hair was parted and tied at the back with a plaited metal rope. Her short dark cloak, so luminous a fabric that it caught and reflected the sheen of all the gaudy restaurant lights, was parted, its ends thrown back over her shoulders. Beneath it she wore the characteristic Martian leather jacket, and short, wide leather trousers ornamented with spun metal fringes and tassels. Most Martian women have an amazonian aspect, but I saw now that _Setta_ Meka was an exception. Her brother, who sat beside her, was a full seven feet or more. A hulking sort of fellow, far less spindly than most of his race, he might have come from the polar outposts beyond the Martian Union. He was bare-headed, his gray-black hair clipped close upon a round bullet head, with the familiar Martian round eyes. I gazed into the face of Molo, as momentarily he turned his head. It was a rough-hewn, strongly masculine face with a hawk-like nose, bushy black brows frowning above deepset round eyes. The face of a keen scoundrel, I could not doubt, though the smooth-plucked gray skin was flushed now with alcholite, and the wide, thin-lipped mouth was leering at the woman across the table from him. Like his sister, he had thrown back his cloak, disclosing a brawny, powerful figure, leather clad, with a wide belt of dangling ornaments, some of which probably were weapons. How long we gazed at this silent colored image of the restaurant table I do not know. I was aware of Halsey's quiet voice: "Look him over, Miss Venza. It depends on you." Another interval passed. It seemed, as we watched, that Molo's interest in his party was very slight. I got the impression, too, that though at first he had seemed to be intoxicated, actually he was not. Nor was his sister. Anxiety seemed upon her; the smile she had for jests seemed forced; and at intervals she would cast a swift, furtive glance across the gay restaurant scene. More drinks arrived. The Earthpeople at the table here seemed upon the verge of stupor; and suddenly it appeared that Molo had completely lost interest in them. With a gesture to his sister, he abruptly rose from his seat. She joined him. They left the table, and a red-clad floor manager of the restaurant came at their call. Then in a moment they were moving across the room. Halsey called sharply into his audiphone: "Francis! Hold us to them if you can." They were standing now by the opened door of one of the Red Spark's private insulated rooms. We caught a glimpse of its interior, a gaily set table with a bank of colored lights over it.
