"Can you roll the boulders away from the hole there?" He was thinking vaguely of teleportation; each boulder was a two-man job.

She said no.

He snarled: "Then why did you bother to come here?"

"Don't talk like that to me," the child said sharply--and he remembered what she thought she was.

"Sorry," he said.

"What I came about," she said calmly, "was the ex-plosion. Can you make an ex-plosion like you said? Back there at the jeep?"

What in G.o.d's name was she talking about?

"Back there," she said with exaggerated patience, "you was thinking about putting all the cartridges together and blowing up the whole d.a.m.n shebang. Remember?"

He did, vaguely. One of a hundred schemes that had drifted through his head.

"I'd sure like to see that ex-plosion," she said. "The way _she_ got things figured, I'd almost just as soon get exploded myself as not."

"I might blow up the logs here and get out," he said slowly. "I think you'd be a mighty handy person to have along, too. Can you get me about a hundred of the machine gun cartridges?"

"They'll miss 'em."

"Sneak me a few at a time. I'll empty them, put them together again and you sneak them back."

She said, slow and troubled: "_She_ set the power of the G.o.ddess to guard them."

"Listen to me, Martha," he said. "I mean _listen_. You'll be doing it for me and they told me the power of the G.o.ddess doesn't work on outsiders. Isn't that right?"

There was a long pause, and she said at last with a sigh: "I sure wish I could see your eyes, Charles. I'll try it, but I'm d.a.m.ned if I would if Dinny didn't stink so bad." She slipped away and Charles tried to follow her with his mind through the darkness, to the silly little rope of vine with the feathers and bones knotted in it--but he couldn't. Too tense again.

Kennedy stirred and muttered complainingly as an icy small breeze cut through the c.h.i.n.ks of the palisade, whispering.

His eyes, tuned to the starlight, picked up Martha bent almost double, creeping toward the smithy-prison. She wore a belt of fifty-caliber cartridges around her neck like a stole. Looked like about a dozen of them. He hastily scooped out a bowl of clean sand and whispered: "Any trouble?"

He couldn't see the grin on her face, but knew it was there. "It was easy," she bragged. "One bad minute and then I checked with you and it was okay."

"Good kid. Pull the cartridges out of the links the way I showed you and pa.s.s them through."

She did. It was a tight squeeze.

He fingered one of the cartridges. The bullet fitted nicely into the socket of an arrowhead. He jammed the bullet in and wrenched at the arrowhead with thumb and forefinger--all he could get onto it. The bra.s.s neck began to spread. He dumped the powder into his little basin in the sand and reseated the bullet.

Charles shifted hands on the second cartridge. On the third he realized that he could put the point of the bullet on a hearth-stone and press on the neck with both thumbs. It went faster then; in perhaps an hour he was pa.s.sing the re-a.s.sembled cartridges back through the palisade.

"Time for another load?" he asked.

"Nope," the girl said. "Tomorrow night."

"Good kid."

She giggled. "It's going to be a h.e.l.l of a big bang, ain't it, Charles?"

"Leave the fire alone," Charles said sharply to Kennedy. The little man was going to douse it for the night.

There was a flash of terrified sense: "They beat you. If the fire's on after dark they beat you. Fire and dark are equal and opposite." He began to smile. "Fire is the negative of dark. You just change the sign, in effect rotate it through 180 degrees. But to rotate it through 180 degrees you have to first rotate it through one degree. And to rotate it through one degree you first have to rotate it through half a degree."

He was beaming now, having forgotten all about the fire. Charles banked it with utmost care, heaping a couple of flat stones for a chimney that would preserve the life of one glowing coal invisibly.

He stretched out on the sand, one hand on the little heap beneath which five pounds of smokeless powder was buried. Kennedy continued to drone out his power-series happily.

Through the c.h.i.n.ks in the palisade a man's profile showed against the twilight. "Shut up," he said.

Kennedy shivering, rolled over and muttered to himself. The spearman laughed and went on.

Charles hardly saw him. His whole mind was concentrated on the spark beneath the improvised chimney. He had left such a spark seven nights running. Only twice had it lived more than an hour. Tonight--tonight, it _had_ to last. Tonight was the last night of the witch-girl's monthly courses, and during them she lost--or thought she lost, which was the same thing--the power of the G.o.ddess.

Primitive aborigines, he jeered silently at himself. A life time wasn't long enough to learn the intricacies of their culture--as occasional executions among them for violating magical law proved to the hilt. His first crude notion--blowing the palisade apart and running like h.e.l.l--was replaced by a complex escape plan hammered out in detail between him and Martha.

Martha a.s.sured him that the witch girl could track him through the dark by the power of the G.o.ddess except for four days a month--and he believed it. Martha herself laid a matter-of-fact claim to keener second sight than her sister because of her virginity. With Martha to guide him through the night and the witch-girl's power disabled, they'd get a day's head start. His hand strayed to a pebble under which jerked venison was hidden and ready.

"But Martha. Are you sure you're not--not kidding yourself? Are you _sure_?"

He felt her grin on the other side of the palisade. "You're sure wishing Uncle Frank was here so you could ask him about it, don't you, Charles?"

He sure was. He wiped his brow, suddenly clammy.

Kennedy couldn't come along. One, he wasn't responsible. Two, he might have to be Charles' cover-story. They weren't too dissimilar in build, age, or coloring. Charles had a beard by now that sufficiently obscured his features, and two years absence should have softened recollections of Kennedy. Interrogated, Charles could take refuge in an imitation of Kennedy's lunacy.

"Charles, the one thing I don't get is this Lee dame. She got a spell on her? You don't want to mess with that."

"Listen, Martha, we've _got_ to mess with her. It isn't a spell--exactly. Anyway I know how to take it off and then she'll be on our side."

"Can I set off the explosion? If you let me set off the explosion, I'll quit my b.i.t.c.hing."

"We'll see," he said.

She chuckled very faintly in the dark. "Okay," she told him. "If I can't, I can't."

He thought of being married to a woman who could spot your smallest lie or reservation, and shuddered.

Kennedy was snoring by now and twilight was deepening into blackness.

There was a quarter-moon, obscured by over-cast. He hitched along the sand and peered through a c.h.i.n.k at a tiny noise. It was the small scuffling feet of a woods-rat racing through the gra.s.s from one morsel of food to the next. It never reached it. There was a soft rush of wings as a great dark owl plummeted to earth and struck talons into the brown fur. The rat squealed its life away while the owl lofted silently to a tree branch where it stood on one leg, swaying drunkenly and staring with huge yellow eyes.
