Like Hell

"Hiding Place," see here.

Inside the zoo ship:

"Torrance and Van Rijn walked through shadows, among monsters; the simulated light of a dozen different suns streamed around them: red, orange, yellow, greenish, and harsh electric blue.
"A thing like a giant shark... tiny flying reptiles, their scales aglitter in prismatic hues..." (p. 577)

Anderson must have known that this description would evoke Hell to his readers:

shadows
monsters
red light
other unpleasant colors
giant shark
flying glittering-scaled reptiles

As I have remarked before, van Rijn, Falkayn and, later, Flandry are accustomed to doing regular business with beings that many of us would find frightening or repulsive. Van Rijn will go anywhere for a profit:

"...bargaining in strange cities or beneath unblue skies and in poisonous winds, for treasures Earth had not yet imagined."
-"Margin of Profit," p. 147.
