The Blue Venus

Out of their mountain hideout came the terrified band of The Renegade. Through the valleys of Venus they swept, seeking a greed-maddened slaver who planned an experiment so cruel and barbaric it would destroy the very foundation of mankind.
The hooded figure of a man detached itself from the shadows beside the door, paused, listening. Nothing stirred. The huge sprawling plantation house was silent and yet alive with the feel of sleepers.
Then from below stairs, he heard a door slam. The tinkle of laughter ascended to his ears. He crouched. His hand slipped inside his coat, fondled the slug gun nestling in its shoulder holster. The voices drifted out of hearing. Uneasy silence settled back over the plantation house.
The hooded man let his breath escape between his teeth. He slid back the door, passed inside like a shadow, shut the door behind him.
The room which he'd entered was lit by the intense, green radiations from the Venusian vegetation. The cold phosphorescent light streamed through the open windows, glinted from a glassite desk, soft flexoglas lounging chairs and sofa. It was the typical office from which the plantation owners directed the affairs of their feudal estates.
As silent as a night hawk, the hooded man drifted to the wall, ran his fingertips over the wood paneling. There was a faint click. The panel slid back revealing a wall safe.
A needle ray of light streamed suddenly from the hooded man's hand, splashed off a paper which he'd drawn from his pocket. He checked the string of figures printed there, returned the paper to his pocket. He worked swiftly, surely. Then with a sigh of satisfaction he swung back the heavy door.
There was a faint thump in the corridor outside the office that broke the silence.
The hooded man snapped erect, the compressed air slug gun in his hand. He was sharply conscious of the hum of Venusian night life outside the windows. The room felt sticky, close. His hand was damp with sweat about the pommel of the slug gun.
