It was almost sundown when Foster and I pushed through the door to the saloon bar at the Ancient Sinner and found a corner table. I watched Foster spread out his maps and papers. Behind us there was a murmur of conversation and the thump of darts against a board.

"When are you going to give up and admit we're wasting our time?" I said. "Two weeks of tramping over the same ground, and we end up in the same place."

"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.'"

"Here's an established fact for you," I said. "We've got fifteen pounds left—that's about forty dollars. It's time we figure out where to go from here, before somebody starts checking up on those phoney papers of ours."

Foster shook his head. "I'm not satisfied that we've exhausted the possibilities here. I've been studying the geometric relationships between the various structures; I have some ideas I want to check. I think it might be a good idea to go out at night, when we can work without the usual crowd of tourists observing every move."

I groaned. "My dogs are killing me," I said. "Let's hope you'll come up with something better—or at least different."

"We'll have a bite to eat here, and wait until dark to start out," Foster said.

The publican brought us plates of cold meat and potato salad. I worked on a thin but durable slice of ham and thought about all the people, somewhere, who were sitting down now to gracious meals in the glitter of crystal and silver. I'd had too many greasy French fries in too many cheap dives the last few years. I could feel them all now, burning in my stomach. I was getting farther from my island all the time—And it was nobody's fault but mine.

"The Ancient Sinner," I said. "That's me."

Foster looked up. "Curious names these old pubs have," he said. "I suppose in some cases the origins are lost in antiquity."

"Why don't they think up something cheery," I said. "Like 'The Paradise Bar and Grill' or 'The Happy Hour Cafe'. Did you notice the sign hanging outside?"

"No."

"A picture of a skeleton. He's holding one hand up like a Yankee evangelist prophesying doom. You can see it through the window there."

Foster turned and looked out at the weathered sign creaking in the evening wind. He looked at it for a long time. When he turned back, there was a strange look around his eyes.

"What's the matter—?" I started.

Foster ignored me, waved to the proprietor, a short fat country man. He came over to the table, wiping his hands on his apron.

"A very interesting old building," Foster said. "We've been admiring it. When was it built?"

"Well, sir," the publican said, "This here house is a many a hundred year old. It were built by the monks, they say, from the monastery what used to stand nearby here. It were tore down by the King's men, Henry, that was, what time he drove the papists out."

"That would be Henry the Eighth, I suppose?"

"Aye, it would that. And this house is all that were spared, it being the brewing-house, as the king said were a worthwhile institution, and he laid on a tithe, that two kegs of stout was to be laid by for the king's use each brewing time."

"Very interesting," Foster said. "Is the custom still continued?"

The publican shook his head. "It were ended in my granfer's time, it being that the Queen were a teetotaller."

"How did it acquire the curious name—'The Ancient Sinner?'"

"The tale is," the publican said, "that one day a lay brother of the order were digging about yonder on the plain by the great stones, in search of the Druid's treasure, albeit the Abbot had forbid him to go nigh the heathen ground, and he come on the bones of a man, and being of a kindly turn, he had the thought to give them Christian burial. Now, knowing the Abbott would nae permit it, he set to work to dig a grave by moonlight in holy ground, under the monastery walls. But the Abbott, being wakeful, were abroad and come on the brother a-digging, and when he asked the why of it, the lay brother having visions of penances to burden him for many a day, he ups and tells the Abbott it were a ale cellar he were about digging, and the Abbott, not being without wisdom, clapped him on the back, and went on his way. And so it was the ale-house got built, and blessed by the Abbott, and with it the bones that was laid away under the floor beneath the ale-casks."

"So the ancient sinner is buried under the floor?"

"Aye, so the tale goes, though I've not dug for him meself. But the house has been knowed by the name these four hundred years."

"Where was it you said the lay brother was digging?"

"On the plain, yonder, by the Druid's stones, what they call Stonehenge," the publican said. He picked up the empty glasses. "What about another, gentlemen?"

"Certainly," Foster said. He sat quietly across from me, his features composed—but I could see there was tension under the surface calm.

"What's this all about?" I asked softly. "When did you get so interested in local history?"

"Later," Foster murmured. "Keep looking bored."

"That'll be easy," I said. The publican came back and placed heavy glass mugs before us.

"You were telling us about the lay brother's finding the bones," Foster said. "You say they were buried in Stonehenge?"

The publican cleared his throat, glanced sideways at Foster.

"The gentlemen wouldna be from the University now, I suppose?" he said.

"Let's just say," Foster said easily, smiling, "that we have a great interest in these bits of lore—an interest supported by modest funds, of course."

The publican made a show of wiping at the rings on the table top.

"A costly business, I wager," he said. "Digging about in odd places and all. Now, knowing where to dig; that's important, I'll be bound."

"Very important," Foster said. "Worth five pounds, easily."

"'Twere my granfer told me of the spot; took me out by moonlight, he did, and showed me where his granfer had showed him. Told me it were a fine great secret, the likes of which a simple man could well take pride in."

"And an additional five pounds as a token of my personal esteem," Foster said.

The publican eyed me. "Well, a secret as was handed down father to son...."

"And, of course, my associate wishes to express his esteem, too," Foster said. "Another five pounds worth."

"That's all the esteem the budget will bear, Mr. Foster," I said. I got out the fifteen pounds and passed the money across to him. "I hope you haven't forgotten those people back home who wanted to talk to us," I said. "They'll be getting in touch with us any time now, I'll bet."

Foster rolled up the bills and held them in his hand. "That's true, Mr. Legion," he said. "Perhaps we shouldn't take the time...."

"But being it's for the advancement of science," the publican said, "I'm willing to make the sacrifice."

"We'll want to go out tonight," Foster said. "We have a very tight schedule."

The landlord dickered with Foster for another five minutes before he agreed to guide us to the spot where the skeleton had been found.

When he left, I began. "Now tell me."

"Look at the signboard again," Foster said. I looked. The skull smiled, holding up a hand.

"I see it," I said. "But it doesn't explain why you handed over our last buck——"

"Look at the hand. Look at the ring on the finger."

I looked again. A heavy ring was painted on the bony index finger, with a pattern of concentric circles.

It was a duplicate of the one on Foster's finger.

The publican pulled the battered Morris Minor to the side of the highway and set the brake.

"This is as close as we best take the machine," he said. We got out, looked across the rolling plain where the megaliths of Stonehenge loomed against the last glow of sunset.

The publican rummaged in the boot, produced a ragged blanket and two long four-cell flashlights, gave one to Foster and the other to me. "Do nae use the electric torches until I tell ye," he said, "lest the whole county see there's folks abroad here." We watched as he draped the blanket over a barbed wire fence, clambered over, and started across the barren field. Foster and I followed, not talking.

The plain was deserted. A few lonely lights showed on a distant slope. It was a dark night with no moon. I could hardly see the ground ahead. A car moved along a distant road, its headlights bobbing.

We moved past the outer ring of stones, skirting fallen slabs twenty feet long.

"We'll break our necks," I said. "Let's have one of the flashlights."

"Not yet," Foster whispered.

Our guide paused; we came up to him.

"It were a mortal long time since I were last hereabouts," he said. "I best take me bearings off the Friar's Heel...."

"What's that?"

"Yon great stone, standing alone in the Avenue." We squinted; it was barely visible as a dark shape against the sky.

"The bones were buried there?" Foster asked.

"Nay, all by theirself, they was. Now it were twenty paces, granfer said, him bein fifteen stone and long in the leg...." The publican muttered to himself, pacing off distances.

"What's to keep him from just pointing to a spot after a while," I said to Foster, "and saying 'This is it'?"

"We'll wait and see," Foster said.

"They were a hollow, as it were, in the earth," the publican said, "with a bit of stone by it. I reckon it were fifty paces from here—" he pointed, "—yonder."

"I don't see anything," I said.

"Let's take a closer look." Foster started off and I followed, the publican trailing behind. I made out a dim shape, with a deep depression in the earth before it.

"This could be the spot," Foster said. "Old graves often sink—" Suddenly he grabbed my arm. "Look...!"

The surface of the ground before us seemed to tremble, then heave. Foster snapped on his flashlight. The earth at the bottom of the hollow rose, cracked open. A boiling mass of luminescence churned, and a globe of light separated itself, rose, bumbling along the face of the weathered stone.

"Saints preserve us," the publican said in a choked voice. Foster and I stood, rooted to the spot, watching. The lone globe rose higher—and abruptly shot straight toward us. Foster threw up an arm and ducked. The ball of light veered, struck him a glancing blow, darted off a few yards, hovered. In an instant, the air was alive with the spheres, boiling up from the ground, and hurtling toward us, buzzing like a hive of yellow-jackets. Foster's flashlight lanced out toward the swarm.

"Use your light, Legion!" he shouted hoarsely. I was still standing, frozen. The globes rushed straight at Foster, ignoring me. Behind me, I heard the publican turn and run. I fumbled with the flashlight switch, snapped it on, swung the beam of white light on Foster. The globe at his head vanished as the light touched it. More globes swarmed to Foster—and popped like soap bubbles in the flashlight's glare—but more swarmed to take their places. Foster reeled, fighting at them. He swung the light—and I heard it smash against the stone behind him. In the instant darkness, the globes clustered thick around his head.

"Foster," I yelled, "run!"

He got no more than five yards before he staggered, went to his knees. "Cover," he croaked. He fell on his face. I rushed the mass of darting globes, took up a stance straddling his body. A sulphurous reek hung around me. I coughed, concentrated on beaming the lights around Foster's head. No more were rising from the crack in the earth now. A suffocating cloud pressed around both of us, but it was Foster they went for. I thought of the slab; if I could get my back to it, I might have a chance. I stooped, got a grip on Foster's coat, and started back, dragging him. The lights boiled around me. I swept the beam of light and kept going until my back slammed against the stone. I crouched against it. Now they could only come from the front.

I glanced at the cleft the lights had come from. It looked big enough to get Foster into. That would give him some protection. I tumbled him over the edge, then flattened my back against the slab and settled down to fight in earnest.

I worked in a pattern, sweeping vertically, then horizontally. The globes ignored me, drove toward the cleft, fighting to get at Foster, and I swept them away as they came. The cloud around me was smaller now, the attack less ravenous. I picked out individual globes, snuffed them out. The hum became ragged, faltered. Then there were only a few globes around me, milling wildly, disorganized. The last half dozen fled, bumbling away across the plain.

I slumped against the rock, sweat running down into my eyes, my lungs burning with the sulphur.

"Foster," I gasped. "Are you all right?"

He didn't answer. I flashed the light onto the cleft. It showed me damp clay, a few pebbles.

Foster was gone.
