emergency rockets burned white in the darkness of space. Duncan was hurled toward the cruiser. Involuntarily he held his breath, looking downward at the vast circle of Pluto. Would he die now? The rockets had flared only briefly; perhaps they had not been noticed. He did not use them again. Instead, he waited, moving steadily onward with no atmosphere to slow him down by its friction. The gravitation of Pluto pulled at both man and ship, but each fell at the same rate—no! The cruiser was pulling away! That meant its masked tubes were still on. Duncan risked another jet. This time his space-boots thumped solidly on the hull. He levered himself toward the side port, which could be opened from without, unless it had been locked. True, when the valve slid aside, the ship’s air would be lost in space, and anyone within the cruiser would die. Duncan grinned savagely. Bracing himself awkwardly, he tugged at levers. The port opened. Duncan was almost flung away from the ship by the blast of air that gusted out. He recovered his balance, swung himself across the threshold— At his feet lay two space-suited bodies, Olcott and Hartman. The faceplates of their Varra Helmets were open, but they had not died of lack of oxygen. That was evident. The frozen, strained whiteness of their features told a different story that Duncan read instantly. The Plutonians had brought death to Hartman and Olcott; they had died in the same manner as Andrea. Duncan closed the port behind him, his face expressionless. Inwardly he was tense as wire, in momentary expectation of cold fury striking at his brain. He stood waiting.

His number might be up, but he had no intention of dying in a crash—not while there was still a possibility of revenging himself on the Plutonian creatures.

Why are you here?” Before Duncan could frame a response, he felt a thrill of sudden urgency flame through him. Something, cold and deadly as space itself, reached into his mind. There was an instant of sickening giddiness— It was gone. The
