was dark and he did not turn on a light. He opened the window and dropped softly to the ground in a narrow space between two buildings.

A grating voice said, “Where you going, punk?”

Grant froze. He wanted to run but couldn’t. He turned. Back at the alley, in the light, was a medium-size, solidly built man with black hair and a long scar on his left cheek. Grant wheeled, but stopped short. In front of him, at the street end, was a huge Neptunian. It was ten feet high. Grant shuddered. He didn’t want that thing too close to him with its razor-sharp teeth and its fondness for blood. He walked toward the Earthman.

They took him into a snow-joint over on Chloride Street. The man led, the Neptunian followed. They went down many flights of stairs carved in the solid purple lava and finally into an elevator. They went farther down.

This, then, was Relegar’s headquarters. The Uranian couldn’t stand radiation for any length of time. Out on Uranus they had almost none, and so Venus, with its very heavy clouds that filtered the sunlight, was one of the few planets where a Uranian could live. Even so, the Uranians on Venus, having an instinctive dread of sunlight because sunlight usually meant radiation, preferred to stay underground. Perhaps it was more like their native world that way, for they lived underground even on Uranus.

They got out of the elevator in a rock cavern and walked a hundred feet. They passed two guards and went through a steel door. They were in a big room, dimly lighted by red bulbs. Giant didn’t like the dimness and he didn’t like the smell. He tried to see.

“Here he is,” said the man.
