"We've hardly begun our investigation," Foster said mildly.

"You keep saying that," I said. "But if there ever was anything in that rock-pile, it's long gone. The archaeologists have been digging over the site for years, and they haven't come up with anything."

"They don't know what to look for," Foster said. "They were searching for indications of religious significance, human sacrifice—that sort of thing."

"We don't know what we're looking for either," I said. "Unless you think maybe we'll meet the Hunters hiding under a loose stone."

"You say that sardonically," Foster said. "But I don't consider it impossible."

"I know," I said. "You've convinced yourself that the Hunters were after us back at Mayport when we ran off like a pair of idiots."

"From what you've told me of the circumstances—" Foster began.

"I know; you don't consider it impossible. That's the trouble with you; you don't consider anything impossible. It would make life a lot easier for me if you'd let me rule out a few items—like leprechauns who hang out at Stonehenge."

Foster looked at me, half-smiling. It had only been a few weeks since he woke up from a nap looking like a senior class president who hadn't made up his mind whether to be a preacher or a movie star, but he had already lost that mild, innocent air. He learned fast, and day by day I had seen his old personality reemerge and—in spite of my attempts to hold onto the ascendency—dominate our partnership.

"It's a failing of your culture," Foster said, "that hypothesis becomes dogma almost overnight. You're too close to your Neolithic, when the blind acceptance of tribal lore had survival value. Having learned to evoke the fire god from sticks, by rote, you tend to extend the principle to all 'established facts.'"
