and even got a degree from Exeter.â
âA degree in what?â
âNatural philosophy, with an emphasis on chemistry and geological studies.â
Grey sipped his whiskey. âYouâre a scientist?â
âAmateur natural philosopher I believe is the correct phrase.â
âWell ⦠holy shit.â
âIndeed.â
âLet me guess,â mused Grey, âthatâs what brought you back to America. Chemistry and geological studies, I mean. Youâre prospecting?â
âCorrect.â
âFor ghost rock?â
âAlso correct,â said Looks Away.
Night had fallen around them like a blanket, leeching away the heat of the day and leaving in its place a moistureless cold. Somewhere out in the blackness something scuttled across the dry sand. Above them the sky was littered with ten billion stars, but even these burning suns looked like chips of ice scattered on a piece of black basalt. Grey got up and took a blanket from his saddle, wrapped it around his shoulders and sat back down. As an afterthought, he walked over to the rock on which Looks Away had arranged all of the guns. He retrieved his own, examined the barrel by firelight, blew through it, dumped out the bullets, and thumbed them back in after inspecting them for grit. Then he slid the gun into its holster. He did not do it with any of the fancy flourishes some men use. Grey was a skilled gunman but he wasnât a showman. He picked up Rileyâs little derringer and slipped that into his pants pocket. His knives were there, too, and he returned them to belt and boot sheaths. Then he went and sat back down. He was aware of Looks Away watching him with intelligent dark eyes. The Sioux made no comment about Grey taking back his weapons, and that told him a lot about their relationship. Maybe not yet friends, maybe not allies, but definitely two men at peace with one another. Fair enough.
âThat explosion,â said Grey as he picked up his tin cup, âwasnât ghost rock.â
âIt was and it wasnât.â
âYou deliberately beating around the bush, or is that a British thing you came back with?â
Starlight sparkled from Looks Awayâs white teeth. âA bit of both, I dare say.â He poured more whiskey into their cups, stared into his for a moment, sipped, sighed, and began speaking. âA lot of people are studying ghost rock, you know. Not just here in America, but all around the world. Itâs not unfair to say that it is the most significant scientific discovery of the nineteenth century. Itâs potentially one of the most important scientific discoveries of all time, and I am not exaggerating when I say that. Of all time.â
He let that hang in the air between them. Grey waited.
âEver since ghost rock was discovered in the Maze out in California,â continued the Sioux, âeveryone has been looking for it. Men have actually left gold and silver mines in order to search for the ore. Think of that. Abandoning a working gold mine in order to find that damnable black rock.â
âWhy shouldnât they? Gold canât make a ship sail faster than the wind,â said Grey. âIt canât make a gun fire twenty times faster than a man can work a rifle lever. It canât make a carriage run without horses.â
âExactly,â said Looks Away, nodding. âGhost rock is all of that and more.â
âHard stuff to find, though. Nowadays, I mean. After the big Quake of â68, folks were finding bits of it everywhere including their own backyards; the supply seems to have dried up.â
Looks Away shook his head. âThatâs not precisely true. A lot of people went to greatâvery great, I dare sayâeffort to collect as many pieces of it as they could. Much of that sundry supply was begged, borrowed, bought, or stolen.â
Grey nodded. âMm. Iâve heard tales. I also heard they found a
