    It is a peaceful reign, held by compact and not by conquest. Again and again, when rebellion threatens the Terran Peace, the natives of the rebellious world have turned against their own people and sided with the men of Terra; not from fear, but from a sense of dedication. There has never been open war. The battle for these worlds is fought in the minds of a few men who stand between worlds; bound to one world by interest, loyalties and allegiance; bound to the other by love. Such a world is Wolf. Such a man was Race Cargill of the Terran Secret Service… At one time Race Cargill had been the best Terran Intelligence agent on the complex and mysterious planet of Wolf. He had repeatedly imperiled his life amongst the half-human and non-human creatures of the sullen world. And he had repeatedly accomplished the fantastic missions until his name was emblazoned with glory. But that had all seemingly ended. For six long years he'd sat behind a boring desk inside the fenced-in Terran Headquarters, cut off there ever since he and a rival had scarred and ripped each other in blood-feud. But when The Door Through Space swung suddenly open, the feud was on again—and with it a plot designed to check and destroy the Terran Empire.

    The only problem is that the Confederacion needs him as one of its twelve Prime Operators for its secret service, the TBII. The TBII wants him as a spy, thief & assassin. It's not, of course, a problem for the Confederacion, which simply uses immersion therapy & hypnotic personality overlay for Otto's training, then sends him out in deep cover, encased in plastiflesh, on a variety of dangerous missions on a number of bizarre worlds.

    They called him Charlie. He had big eyes, abundant body hair and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him. All they knew was that his corpse was 50,000 years old; and that meant that this man had somehow lived long before he ever could have existed!
