Ricardo's Virus

A knife wound can be a serious matter on Earth. On Venus, it's a six-hour flow into vilest eternity .
Graff Dingle stolidly watched yellow mold form around the stiletto hole in his arm. He smelled the first faint jasmine odor of the disease and glanced up to where the sun glowed unhappily behind a mass of dirty clouds and wind-driven rain.
Dingle kicked morosely at the Heatwave thug left behind to ambush him, and the charred body turned soughingly in the mud. Be seeing you, bully-boy, in about five and a half hours. Your electroblast may have missed me, but it cooked my antiseptic pouch into soup. It made that last knife-thrust really rate.
There was a dumb dryhorn blunder, Graff reflected, sneering at himself out of a face that was dark from life-long exposure to a huge sun. Bending over an enemy before making certain he was burned to a crisp.
But he'd had to search the man's clothing for a clue to the disappearance of Greta and Dr. Bergenson and—even above Greta—the unspeakably precious cargo of lobodin they'd been flying in from Earth.
So I'll pay for my hurry , he thought. Like one always does in the Venusian jungle.
Ricardo's Virus was viciously prompt: six hours after its light, saffron globules had formed in an open wound, you were dead. And no frantic surgery, no pathetic attempts at drainage, could save you. Graff should know. His parents, his brothers and sisters had been a small fraction of the New Kalamazoo death totals due to cuts and scratches observed too late for antisepsis. The virus had accounted for most of three generations of Venusian colonists, including Vilfredo Ricardo himself, the first man to set hesitant foot on the swampy planet. Ricardo had merely skinned his hand on his new flagpole.
Nasty to die of the filthy mold before he knew what had happened to the Bergensons. Not that he had a personal interest in the matter any more for Greta wouldn't be marrying a corpse when she could pick any one of a hundred extremely live and woman-hungry pioneers. But her father was the only doctor in the tiny settlement. And the loss of the lobodin meant Ricardo's Virus would tuck many more New Kalamazoo colonists into seepy graves before the year was out.
