Here Janice Darell pointed up toward the flattened glass dome that roofed the room. "There is old Mother Earth looking down at us, and the sun is peeping around her rim," she said. "See how the light of Sol sifts through the terrestrial atmosphere. There is a streak of red, of gold, of opal, and beyond are the stars and the blackness of space."

"The contrast of the forces of darkness with those of light," Shelby put in softly.

Hekki was smiling absently. "There are many contrasts," he mused. "The contrast of life and death, of power and weakness, of nightmare and reality."

Words popped into Austin Shelby's head, and, carelessly, he uttered them without thinking: "You often walk with your nightmares, don't you, Hekalu?"

A hard light came into the Martian's eyes as he stared straight at the Earthman. "Perhaps," he said, "and you, Mr. Shelby, often walk in your sleep!" But apparently the incident was immediately forgotten.

Austin wondered how much the girl knew about the luxurious Hekalu. A quick glance of intelligence passed between them.

"I'll have to pack now," Janice said. "Won't you boys walk along with me a little ways?" She took Austin's arm as they arose. Hekki fell in beside them. At the entrance to the corridor which led to the girl's stateroom they paused.

"My business will occupy me tonight and tomorrow," said Hekalu, "so I shall bid you goodbye until, let us say, the following evening, Jan, but if you like I shall have Alka take you home."

"Mr. Shelby has asked permission to perform that little service, you industrious old business man," she replied mischievously. And again that dark shadow flickered momentarily on the Martian's features.
