BONE _Illustrated by Ed Emsh_ _The aliens wooed Earth with gifts, love, patience and peace._ _Who could resist them? After all, no one shoots Santa Claus!_ * * * * * The rifle lay comfortably in his hands, a gleaming precision instrument that exuded a faint odor of gun oil and powder solvent. It was a perfect specimen of the gunsmith's art, a semi-automatic rifle with a telescopic sight--a precisely engineered tool that could hurl death with pinpoint accuracy for better than half a mile. Daniel Matson eyed the weapon with bleak gray eyes, the eyes of a hunter framed in the passionless face of an executioner. His blunt hands were steady as they lifted the gun and tried a dry shot at an imaginary target. He nodded to himself. He was ready. Carefully he laid the rifle down on the mattress which covered the floor of his firing point, and looked out through the hole in the brickwork to the narrow canyon of the street below. The crowd had thickened. It had been gathering since early morning, and the growing press of spectators had now become solid walls of people lining the street, packed tightly together on the sidewalks. Yet despite the fact that there were virtually no police, the crowd did not overflow into the streets, nor was there any of the pushing crowding impatience that once attended an assemblage of this sort. Instead there was a placid tolerance, a spirit of friendly good will, an ingenuous complaisance that grated on Matson's nerves like the screeching rasp of a file drawn across the edge of thin metal. He shivered uncontrollably. It was hard to be a free man in a world of slaves.
