It was a medium-sized room, clearly a dispensary. There was an operating table, a sterilizer, tall glass-fronted instrument cabinets and a refrigerator. At the far end of the room a hulking, bear-like man sat behind a magnalloy desk. The nameplate on the desk said: Hal H. Wilcox, M.D.

"Howdy, gents," said Dr. Hal H. Wilcox, shattering the moon-silence with a vengeance. "What can I do for you?" he was all smiles.

That smile, decided Pell, didn't quite match the shrewdness of his eyes. Have to watch this boy, maybe. There was a big quartz window behind the man so that for the moment Pell saw him almost in silhouette. "We're from Current magazine," said Pell. "I'm Dick Pell and this is Steve Kronski. You got our radio, I guess."

"Oh, yes. Yes, indeed." Wilcox creaked way back in his chair. "You're the fellas want to do a story on us moon surgeons."

"That's right." Pell fumbled a little self-consciously with the gravity weights clipped to his trousers. Took a while for moon visitors to get used to them, everybody said.

"Well, I don't know exactly as how there's much of a story in what we do. We're just a bunch of sawbones stationed here, that's all."

"We're interested in the diseases peculiar to the moon," said Pell. "For instance, why do the permanent residents up here have to have an inoculation every year?"

"That's for the Venusian rash. Thought everybody knew that."

"Venusian rash?"

"Nearest thing we ever had to it on Earth was Rocky Mountain Spotted Fever. It's a rickettsia disease. Makes a fella pretty sick; sometimes kills him in two, three days. It started when they had those Venusian construction workers and tunnel men here, oh, long before the war. Under certain conditions the rickettsia stays dormant and then pops up again."
