Chapter 7: Plague

Dr. Feldman leaned back from his microscope and lighted another bracky weed. He glanced about the room and sighed wearily. Maybe he’d been better off when he had no friends and couldn’t risk the safety of others in an effort to do research that was the highest crime on two worlds.

The evidence of his work was hidden thirty feet beyond his former laboratory in Jake’s village, with a tunnel that led from another root-cellar. The theory was the old one that the best place to avoid discovery was where you had already been discovered. If their spies had identified his former hangout, they’d never expect to have him set up research nearby. It was a nice theory, but he wasn’t sure of it.

Jake looked up from a cot where he’d been watching the improvised culture incubator. “Stop tearing yourself to bits, Doc. We know the danger and we’re still darned glad to have you here working on this.”

“I’m trying to put myself together into a whole man,” Doc told him. “But I seem to come out wholly a fool.”

“Yeah, sure. Sometimes it takes a fool to get things done; wise men wait too long for the right time. How’s the bug hunt?”

Doc grunted in disgust and swung back to the microscope. Then he gave up as his tired eyes refused to focus. “Why don’t you people revolt?”

“They tried it twice. But they were just a bunch of pariahs shipped here to live in peonage. They couldn’t do much. The first time Earth cut off shipments and starved them. Next time the villages had the answer to that but the cities had to fight for Earth or starve, so they whipped us. And there’s always the threat that Earth could send over unmanned war rockets loaded with fissionables.”

“So it’s hopeless?”

“So nothing! The Lobbies are poisoning themselves, like cutting off Medical service until they cut themselves out of a job. It’s just a matter of time. Go back to the bugs, Doc.”

Doc sighed and reached for his notes. “I wish I knew more Martian history. I’ve been wondering whether this bug may not have been what killed off the old Martians. Something had to do it, the way they disappeared. I wish I knew enough to make an investigation of those ruins out there.”

“Durwood!” Jake had propped himself on an elbow, staring at Doc in surprise.

Doc scowled. “Clive Durwood, you mean? The archeologist who dug up what little we know about the ruins?”

“Yeah, before he went back to Earth and started living off his lectures. He came here again three years ago and dropped dead in Edison on the way to some other ruins. Heart failure, they called it, though it was more like the two old farmers who ran themselves to death last month. I saw him when they buried him. His face looked funny, and I think he had those little specks, though I may remember wrong.” He grimaced. “Mars is tough, Doc; it has to be. Some of the plant seeds Durwood found in the ruins grew! Maybe your bugs waited a million years till we came along.”

“What about the farmers? Did they meet Durwood?”

Jake nodded. “Must have. He lived in their village most of the time.”

Doc went through his notes. He’d asked for reports on all deaths, and he finally found the account. The two old men had been nervous and fidgety for weeks. They were twins, living by themselves, and nobody paid much attention. Then one morning both were seen running wildly in circles. The village managed to tie them up, but they died of exhaustion shortly after.

It wasn’t a pretty picture. The disease might have an incubation period of nearly fifteen years, judging by the length of time it had taken to hit Durwood. It must spread from person to person during an early contagious stage, leaving widening circles behind Durwood and those first infected. When matured, any other sickness would set it off, with few symptoms of its own. But without help, it still killed its victims, apparently driving them madly toward frenzied physical effort.

He studied the culture on a slide again. He’d tried Koch’s method to get a pure strain, splattering the bugs onto a native starchy root and plucking off individual colonies. About twenty specimens had been treated with every chemical he could find. So far he’d found a few things that seemed to stop their growth, but nothing that killed them, except stuff far too harsh to use in living tissue.

He had nearly forty cases of deaths that showed symptoms now, and he went back over them, looking for anything in common that went back ten to twenty years before death. There were no rashes nor blisters. A few had had apparent colds, but such were too common to mean anything.

Only one thing appeared, about fourteen years before their deaths. The people interviewed about the victims might be vague about most things, but they remembered the time when “Jim had the jumping headache.”

“Jake,” Doc called, “what’s jumping headache? Most people seem to have it some time or other, but I haven’t run across a case of it.”

“Sure you have, Doc. Mamie Brander’s little girl a few weeks ago. Feels like your pulse is going to rip your skull off, right here. Can’t eat because chewing drives you crazy. Back of your head, neck and shoulders swell up for about a week. Then it goes away.”
