On Venus he had seen powerful land-owners growing fat and rich while native Kamalis and Sarakans toiled in the swamps. On Mars he had toured the luxurious plaisances and estates of the D.O.F.C—the Descendents of the First Colonists—and a hundred miles out in the desert had walked through the stinking narrow streets of the Thedras, the despised aboriginals of the West Plateaus.

Then and there Jimmy Starr had decided to add a twofold purpose to his life. He would do all in his power to aid the oppressed poor, and he would strain every effort to plague the lives of the superiors class. Some day, in some way, that effort would lead him, he felt sure, to his father's murderer and the stolen Chronicles cypher. The only item in question was the time element.

He spent six months in his father's private library, studying everything he could find on locks, time vaults, hermetic chambers and impenetrable walls. Six months more went into a thorough reading on the various subjects of criminology, micro-fingerprints, robot detectors.

He had begun quietly at first, a small art treasure taken from the collection of some greedy superiors millionaire. But gradually the daring of those thefts, the absolute lack of clues, with the exception of the tell-tale blue card, had attracted attention. In a year his fame had spread as far as Pluto. In six months more the Nebula was a byword in every tongue.

The police had sworn action, the press had chuckled, and the public had looked with open admiration on this benefactor of the downtrodden.

Now all that was over. The Nebula was a criminal. He was accused of murder.

Slowly Jimmy Starr got out of bed and began to dress. Funny, he had never thought of this contingency. Someone had seen an opportunity to profit by his name, and had utilized it with cold-blooded efficiency.

He lit a cheroot and stood there smoking. A bell tinkled behind him, announcing a call on the visiphone. He crossed to the panel, touched a stud. A voice came out of the speaker, but no image appeared on the vision screen.

"Good morning, Nebula!"

An electric shock swept through him. His cheroot slipped from his fingers.
