rystal City made up in violence what it lacked in size. It was a typical boom town of the Lunar mining regions. Mining and a thriving spacefreight trade in heavy metals made it a mecca for the toughest space-screws and hardest living prospector-miners to be found in the inhabited worlds. Saloons and cheap lodging-houses, gambling dens and neon-washed palaces of expensive sin, the jail and a flourishing assortment of glittery funeral parlors faced each other across two main intersecting streets. X marked the spot and life was the least costly of the many commodities offered for sale to rich-strike suckers who funneled in from all Luna.

Briefly, he acquainted irritable officialdom with details of his find in the Appenines. The sergeant was fat, belligerent and unphilosophical. "You stink," said the sergeant, twisting his face into more repulsive suggestion of a distorted rubber mask. Tod Denver tried to continue. The sergeant cut him off with a rude suggestion. "So what?" added the official. "Suppose you did run into a murder. Do I care? Maybe you killed the old guy yourself and are trying to cover up. I don't know." He scowled
