"Well, sir, I'm glad to hear that. I reckon I can bring the job in at a thousand dollars pretty well." He fixed me with a hard clear eye, waiting to see if I'd flinch, but I just hauled my purse out and grinned at him.

"Price is no object to Holy Mother Church," I said. "Shall we say, half the payment in advance?"

I counted out Chilean gold dollars while he watched, sucking his teeth, and I went on: "In fact, we were thinking of having rosaries made up as a gift for the whole College of Cardinals.

Assuming, of course, that you have enough of that particular beautiful vein of quartz. Do you know where it was mined?"

"Don't know, sir, and that's a fact," he told me. "Miner brought in a sackful a week ago. He reckoned he could get more for it at a jeweler's because of the funny color. There's more'n enough of it in my back room to make your beads, I bet."

"Splendid," I said. "But do you recall the miner's name, in case we do need to obtain more?"

"Ayeh." Mr. Gainsborg picked up a dollar and inspected it. "Isaiah Stuckey, that was the fellow's name. Didn't say where his claim was, though. They don't tell, as a general rule."

"Understandable. Do you know where I might find the man?"

"No, sir, don't know that. He didn't have a red cent until I paid for the quartz, I can tell you; so I reckon the next place he went was a hotel." Mr. Gainsborg looked disdainful. "Unless he went straight for the El Dorado or a whorehouse, begging your pardon. Depends on how long he'd been in the mountains, don't it?"

I sighed and shook my head. "This is a city of temptation, I am afraid. Can you describe him for me?"

Mr. Gainsborg considered. "Well, sir, he had a beard."

Great. I was looking for a man with a beard in a city full of bearded men. At least I had a name.

So I spent the rest of that day trudging from hotel to boarding house to tent, asking if anybody there had seen Isaiah Stuckey. Half the people I asked snickered and said, "No, why?" and waited for a punch line. The other half also replied in the negative, and then asked my advice on matters spiritual. I heard confessions from seventeen prostitutes, five drunks and a transvestite before the sun sank behind Knob Hill, but I didn't find Isaiah Stuckey.

By twilight, I had worked my way out to the landlocked ships along what would one day be Battery and Sansome Streets, though right now they were just so many rickety piers and catwalks over the harbor mud. I teetered up the gangplank of one place that declared itself the MAGNOLIA HOTEL, by means of a sign painted on a bedsheet hung over the bow. A grumpy-looking guy was swabbing the deck.

"We don't rent to no goddamn greasers here," he informed me. "Even if you is a priest."

"Well, now, my son, Christ be my witness I've not come about taking rooms," I said in the thickest Dublin accent I could manage, "Allow me to introduce myself! Father Ignatius Costello. I'm after searching for a poor soul whose family's in sore need of him, and him lost in the gold fields this twelvemonth. Do you rent many rooms to miners, lad?"

"Sure we do," muttered the guy, embarrassed. "What's his name?"

"Isaiah Stuckey, or so his dear old mother said," I replied.

"Him!" The guy looked up, righteously indignant now. He pointed with his mop at a vast expanse of puke on the deck. "That's your Ike Stuckey's work, by God!"

I recoiled. "He's never got the cholera?"

"No, sir, just paralytic drunk. You ought to smell his damn room, after he lay in there most of a week! Boss had me fetch him out, plastered or not, on account of he ain't paid no rent in three days. I got him this far and he heaved up all over my clean floor! Then, I wish I may be struck down dead if he don't sober up instant and run down them planks like a racehorse! Boss got a shot off at him, but he kept a-running. Last we saw he was halfway to Kearney Street."

"Oh, dear," I said. "I don't suppose you'd have any idea where he was intending to go, my son?"

"No, I don't," said the guy, plunging his mop in its pail and getting back to work. "But if you run too, you can maybe catch the son of a-" he wavered, glancing up at my ecclesiastical presence, "-gun. He ain't been gone but ten minutes."

I took his advice, and hurried off through the twilight. There actually was a certain funk lingering in the air, a trail of unwashed-Stuckey molecules, that any bloodhound could have picked up without much effort-not that it would have enjoyed the experience-and incidentally any cyborg with augmentedsenses could follow too.

So I was slapping along in my sandals, hot on Stuckey's trail, when I ran into Mendoza at the corner.

"Hey, Joseph!" She waved at me cheerily. "You'll never guess what I found!"

"Some plant, right?"

"And how! It's a form of Lupinus with-"

"That's fascinating, doll, and I mean that sincerely, but right now I could really use a lift." I jumped and swung up into the saddle behind her, only to find myself sitting on something damp. "What the hell-"

"That's my Lupinus. I dug up the whole plant and wrapped the root ball in a piece of my petticoat until I can transplant it into a pot. If you've squashed it, I'll wring your neck," she told me.

"No, it's okay," I said. "Look, could we just canter up the street that way? I'm chasing somebody and I don't want to lose him."

She grumbled, but dug her heels into the horse's sides and we sped off, though we didn't go very far very fast because the street went straight uphill.

"It wouldn't have taken us ten minutes to go back and drop my Lupinus at the hotel, you know,"

Mendoza said. "It's a really rare subspecies, possibly a mutant form. It appears to produce photoreactive porphyrins."

"Honey, I haven't got ten minutes," I said, wrootching my butt away from the damn thing. "Wait!

Turn left here!" Stuckey's trail angled away down Kearney toward Portsmouth Square, so Mendoza yanked the horse's head around and we leaned into the turn. I peered around Mendoza, trying to spot any bearded guy staggering and wheezing along. Unfortunately, the street was full of staggering bearded guys, all of them converging on Portsmouth Square.

We found out why when we got there.

Portsmouth Square was just a sandy vacant lot, but there were wire baskets full of pitch and redwood chips burning atop poles at its four corners, and bright-lit board and batten buildings lined three sides of it. The fourth side was just shops and one adobe house, like a row of respectable spinsters frowning down on their neighbors, but the rest of the place blazed like happy Gomorrah.

"Holy smoke," said Mendoza, reining up. "I'm not going in there, Joseph."

"It's just mortals having a good time," I said. Painted up on false fronts, garish as any Old West fantasy, were names like The Mazourka, Parker House, The Varsouvienne, La Souciedad, Dennison's Exchange, The Arcade. All of them were torchlit and proudly decked in red, white and blue, so the general effect was of Hell on the Fourth of July.

"It's brothels and gambling dens," said Mendoza.

"It's theaters, too," I said defensively, pointing at the upstairs windows of the Jenny Lind.

"And saloons. What do you want here?"

"A guy named Isaiah Stuckey," I said, leaning forward. His scent was harder to pick out now, but...over there..."He's the miner who found our quartz. I need to talk to him. Come on, we're blocking traffic! Let's try that one. The El Dorado."

Mendoza gritted her teeth but rode forward, and as we neared the El Dorado the scent trail grew stronger.

"He's in here," I said, sliding down from the saddle. "Come on!"

"I'll wait outside, thank you."

"You want to wait here by yourself, or you want to enter a nice civilized casino in the company of a priest?" I asked her.

She looked around wildly at the happy throng of mortals. "Damn you anyway," she said, and dismounted. We went into the El Dorado.

Maybe I shouldn't have used the words nice civilized casino. It was a big square place with bare board walls, and the floor sloped downhill from the entrance, because it was just propped up on pilings over the ash-heaps and was already sagging. Wind whistled through the planks, and there is no night air so cold as in San Francisco. It gusted into the stark booths, curtained off with thumbtacked muslin, alongone wall where the whores were working. It was shanty-town squalor no Hollywood set designer would dream of depicting.

But the El Dorado had all the other trappings of an Old West saloon, with as much rococo finery as could be nailed on or propped against the plank walls. There were gilt-framed paintings of balloony nude women. There was a grand mirrored bar at one end, cut glass glittering under the oil lamps. Upon the dais a full orchestra played, good and loud, and here again the Stars and Stripes were draped, swagged and rosetted in full glory.

At the gambling tables were croupiers and dealers in black suits, every one of them a gaunt Doc Holliday clone presiding over monte, or faro, or diana, or chuck-a-luck, or plain poker. A sideboard featured free food for the high rollers, and a lot of ragged men-momentary millionaires in blue jeans, back from the gold fields for the winter-were helping themselves to pie and cold beef. At the tables, their sacks of gold dust or piles of nuggets sat unattended, as safe as anything else in this town.

I wished I wasn't dressed as a friar. This was the kind of spot a cyborg with the ability to count cards could earn himself some money to offset operating expenses. I might have given it a try anyway, but beside me Mendoza was hyperventilating, so I just shook my head and focused on my quarry.

Isaiah Stuckey was in here somewhere. At the buffet table? No...

At the bar? No...Christ, there must have been thirty guys wearing blue jeans and faded red calico shirts in here, and they all stank like bachelors. Was that him? The beefy guy looking around furtively?

"Okay, Mendoza," I said, "if you were a miner who'd just recovered consciousness after a drinking binge, stone broke-where would you go?"

"I'd go bathe myself," said Mendoza, wrinkling her nose. "But a mortal would probably try to get more money. So he'd come in here, I guess. Of course, you can only win money in a game of chance if you already have money to bet-"

"STOP, THIEF!" roared somebody, and I saw the furtive guy sprinting through the crowd with a sack of gold dust in his fist. The croupiers had risen as one, and from the recesses of their immaculate clothing produced an awesome amount of weaponry. Isaiah Stuckey-boy, could I smell him now!-crashed through a back window, pursued closely by bullets and bowie knives.

I said something you don't often hear a priest say and grabbed Mendoza's arm. "Come on! We have to find him before they do!"

We ran outside, where a crowd had gathered around Mendoza's horse.

"Get away from that!" Mendoza yelled. I pushed around her and gaped at what met my eyes. The sorry-looking bush bound behind Mendoza's saddle was...glowing in the dark, like a faded neon rose. It was also shaking back and forth, but that was because a couple of mortals were trying to pull it loose.

They were a miner, so drunk he was swaying, and a hooker only slightly less drunk, who was holding the miner up by his belt with one hand and doing her best to yank the mutant Lupinus free with the other.

"I said leave it alone!" Mendoza shoved me aside to get at the hooker.

"But I'm gettin' married," explained the hooker, in as much of a voice as whiskey and tobacco had left her. "An' I oughter have me a buncha roses to get married holding on to. 'Cause I ain't never been married before and I oughter have me a buncha roses."

"That is not a bunch of roses, you stupid cow, that's a rare photoreactive porphyrin-producing variant Lupinus specimen," Mendoza said, and I backed off at the look in her eyes and so did every sober man there, but the hooker blinked.

"Don't you use that kinda language to me," she screamed, and attempted to claw Mendoza's eyes out. Mendoza ducked and rose with a roundhouse left to the chin that knocked poor Sally Faye, or whoever she was, back on her ass, and her semiconscious fiance went down with her.

All the menfolk present, with the exception of me, drew back eagerly to give the ladies room. I jumped forward and got Mendoza's arm again.

"My very beloved daughters in Christ, is this any way to behave?" I cried, because Mendoza, with murder in her eye, was pulling a gardening trowel out of her saddlebag. Subvocally I transmitted, Are you nuts? We've got to go after Isaiah Stuckey!

Snarling, Mendoza swung herself back into the saddle. I had to scramble to get up there too, hitchingmy robe in a fairly undignified way, which got boffo laughs from the grinning onlookers before we galloped off into the night.

"Go down to Montgomery Street!" I said. "He probably came out there!"

"If one of the bullets didn't get him," said Mendoza, but she urged the horse down Clay and made a fast left onto Montgomery. Halfway along the block we slowed to a canter and I leaned out, trying to pick up the scent trail again.

"Yes!" I punched the air and nearly fell off the horse. Mendoza grabbed my hood, hauling me back up straight behind her.

"Why the hell is it so important you talk to this mortal?" she demanded.

"Head north! His trail goes back toward Washington Street," I said. "Like I said, babe, he sold that quartz to Gainsborg."

"But we already know it tested positive for your lichen," said Mendoza.

At the next intersection we paused as I sniffed the air, and then pointed forward. "He went thataway!

Let's go. We want to know where he got the stuff, don't we?"

"Do we?" Mendoza kicked the horse again-I was only grateful the Company hadn't issued her spurs-and we rode on toward Jackson. "Why should we particularly need to know where the quartz was mined, Joseph? I've cultured the lichen successfully. There'll be plenty for the Company labs."

"Of course," I said, concentrating on Isaiah Stuckey's scent. "Keep going, will you? I think he's heading back toward Pacific Street."

"Unless the Company has some other reason for wanting to know where the quartz deposit is," said Mendoza, as we came up on Pacific.

I sat up in the saddle, closing my eyes to concentrate on the scent. There was his earlier track, but...yes...he was heading uphill again. "Make another left, babe. What were you just saying?"

"What I was about to say was, I wonder if the Company wants to be sure nobody else finds this very valuable deposit of quartz?" said Mendoza, as the horse snorted and laid its ears back; it wasn't about to gallop up Pacific. It proceeded at a grudging walk.

"Gee, Mendoza, why would Dr. Zeus worry about something like exclusive patent rights on the most valuable bioremediant substance imaginable?" I said.

She was silent a moment, but I could feel the slow burn building.

"You mean," she said, "that the Company plans to destroy the original source of the lichen?"

"Did I say that, honey?"

"Just so nobody else will discover it before Dr. Zeus puts it on the market, in the twenty-fourth century?"

"Do you see Mr. Stuckey up there anyplace?" I rose in the saddle to study the sheer incline of Pacific Street.

Mendoza said something amazingly profane in sixteenth-century Galician, but at least she didn't push me off the horse. When she had run out of breath, she gulped air and said: "Just once in my eternal life I'd like to know I was actually helping to save the world, like we were all promised, instead of making a lot of technocrats up in the future obscenely rich."

"I'd like it too, honest," I said.

"Don't you honest me! You're a damned Facilitator, aren't you? You've got no more moral sense than a jackal!"

"I resent that!" I edged back from her sharp shoulder blades, and the glow-in-the-dark mutant Lupinus squelched unpleasantly under my behind. "And anyway, what's so great about being a Preserver? You could have been a Facilitator like me, you know that, kid? You had what it took.

Instead, you've spent your whole immortal life running around after freaking bushes!"

"A Facilitator like you? Better I should have died in that dungeon in Santiago!"

"I saved your LIFE, and this is the thanks I get?"

"And as for freaking bushes, Mr. Big Shot Facilitator, it might interest you to know that certain rare porphyrins have serious commercial value in the data storage industry-"

"So, who's making the technocrats rich now, huh?" I demanded. "And have you ever stopped toconsider that maybe the damn plants wouldn't be so rare if Botanist drones like you weren't digging them up all the time?"

"For your information, that specimen was growing on land that'll be paved over in ten years,"

Mendoza said coldly. "And if you call me a drone again, you're going to go bouncing all the way down this hill with the print of my boot on your backside."
