Cahill laughed. "Have it your way, Farradyne. Well, tell me, do we have a layover at Denver, or is it better if we take off immediately for Mercury?"

"Cinnabar or Hell City?"

"Cinnabar, if it makes any difference."

"Mercury, Schmercury, I didn't know there was anything there but the central heating plant."

"Isn't much," admitted Cahill. "But enough. The—"

His voice trailed away as Norma's high heels came clicking up the circular stairway, back toward the salon. "I thought I'd have a cigarette and a drink with company before I go to bed," she announced in a tone of voice that Farradyne had not heard her use before. With gracious deftness, Norma made three highballs of White Star and water and handed two of them to the men. She let her fingers linger over Farradyne's very briefly, and over Cahill's longer. She lounged in a chair across from them, all curves and softness, with only that strange, disinterested look in her eyes to give her away.

Farradyne found this a bit difficult to explain to himself. The evening had been a series of paradoxes; Norma's change from vixen to the lady of languid grace did not ring true. He had been aware of her ability to reason coldly, brought about by her burned-out emotional balance which was so dulled that her thinking was mechanically unemotional and therefore inclined to be frightfully chilled logic. But Farradyne's grasp of the problem was incomplete. Norma had claimed that she knew the emotions by name and definition, that once she had felt them, but that now she only knew how they worked. Farradyne found it hard to believe that she was so well-schooled in her knowledge that she could put on the act of having them when she obviously did not.

She did not even force herself upon them; when her cigarette and her drink were gone, Norma got up, excused herself and quietly went below.

"Me too," said Cahill.

Farradyne led him down to a stateroom and waved him in. "See you in the morning," he said. Cahill nodded his goodnight and Farradyne went on to his own room to think.
