_The first ripples of blue fire touched Dio's men. Bolts of it fastened on gun-butts, and knuckles. Men screamed and fell. Jill cried out as he tore silver ornaments from her dress._





Mel Gray flung down his hoe with a sudden tigerish fierceness and stood erect. Tom Ward, working beside him, glanced at Gray's Indianesque profile, the youth of it hardened by war and the hells of the Eros prison blocks.

A quick flash of satisfaction crossed Ward's dark eyes. Then he grinned and said mockingly.

"Hell of a place to spend the rest of your life, ain't it?"

Mel Gray stared with slitted blue eyes down the valley. The huge sun of Mercury seared his naked body. Sweat channeled the dust on his skin. His throat ached with thirst. And the bitter landscape mocked him more than Wade's dark face.

"The rest of my life," he repeated softly. "The rest of my life!"

He was twenty-eight.

Wade spat in the damp black earth. "You ought to be glad--helping the unfortunate, building a haven for the derelict...."

"Shut up!" Fury rose in Gray, hotter than the boiling springs that ran from the Sunside to water the valleys. He hated Mercury. He hated John Moulton and his daughter Jill, who had conceived this plan of building a new world for the destitute and desperate veterans of the Second Interplanetary War.

"I've had enough 'unselfish service'," he whispered. "I'm serving myself from now on."

Escape. That was all he wanted. Escape from these stifling valleys, from the snarl of the wind in the barren crags that towered higher than Everest into airless space. Escape from the surveillance of the twenty guards, the forced companionship of the ninety-nine other veteran-convicts.

Wade poked at the furrows between the sturdy hybrid tubers. "It ain't possible, kid. Not even for 'Duke' Gray, the 'light-fingered genius who held the Interstellar Police at a standstill for five years'." He laughed. "I read your publicity."

Gray stroked slow, earth-stained fingers over his sleek cap of yellow hair. "You think so?" he asked softly.

Dio the Martian came down the furrow, his lean, wiry figure silhouetted against the upper panorama of the valley; the neat rows of vegetables and the green riot of Venusian wheat, dotted with toiling men and their friendly guards.

Dio's green, narrowed eyes studied Gray's hard face.

"What's the matter, Gray? Trying to start something?"

"Suppose I were?" asked Gray silkily. Dio was the unofficial leader of the convict-veterans. There was about his thin body and hatchet face some of the grim determination that had made the Martians cling to their dying world and bring life to it again.

"You volunteered, like the rest of us," said the Martian. "Haven't you the guts to stick it?"

"The hell I volunteered! The IPA sent me. And what's it to you?"

"Only this." Dio's green eyes were slitted and ugly. "You've only been here a month. The rest of us came nearly a year ago--because we wanted to. We've worked like slaves, because we wanted to. In three weeks the crops will be in.
