T yler couldn’t tell whether the belt Orr made him wear really was rigged with explosives, but it was definitely uncomfortable. It was tight enough that he couldn’t possibly slide it down over his hips. The belt was made of heavy-duty nylon. Even if he found a cutting tool, it would take him several minutes to saw through it. The clasp and key-release mechanism were integrated into the unit housing the explosives, so if he tried to pry it apart, he might set it off.
He wasn’t worried about the C4 itself. The explosive was extremely stable and couldn’t be detonated by impact, even by a gunshot. Tyler always hated movies that showed someone blowing up a brick of C4 by shooting it, because the scenario was complete fiction.
Stacy looked as uncomfortable with her belt as he did, and Tyler was beginning to have second thoughts about how hastily he’d assumed that she was helping Orr. Maybe it was just his rationalization for not wanting to seem like a sucker, but he didn’t want to believe Stacy was capable of betraying him.
But if she wasn’t in league with Orr, Tyler couldn’t figure out how Orr knew every one of their movements. Orr might have learned about the museum heist from the news, but with the tracker on the plane during their stay in Athens, there was no way he could have known that the shootout at the Parthenon involved them. It was almost as if he had access to a second GPS signal…
Tyler suddenly remembered Orr smashing their cell phones. Stacy’s phone had been the only piece of electronics they’d had with them the entire time. Tyler’s phone had gotten ruined when it was dunked in the river. Orr could have been tracking the signal in Stacy’s phone from the beginning. Tyler had been so fixated on the tracker in the geolabe that it never occurred to him that Orr had a backup, which must have been why Orr had made it so easy to find.
Tyler couldn’t be sure that he was right, but he had renewed faith that Stacy was innocent. So Orr was either toying with them or he was trying to keep Tyler and Stacy from trusting each other. Divide and conquer. Tyler would play along for now.
Gaul found a rare parking spot two blocks away from the church at Piazza San Gaetano. They got out and began walking, with Gaul and Orr careful to stay behind Tyler and Stacy. The shops lining the narrow streets were all closed, and the bustle of activity Tyler had seen earlier in the day had dwindled. Scooters occasionally passed them, and the few pedestrians were making their way to tiny restaurants or the entryways of their walkup apartments.
Along the way, Tyler saw a sign for Napoli Sotterranea, the tour service that took people through the ancient passageways winding their way under the city. When he and Stacy had come this way in the afternoon, Tyler had stopped in to ask some questions.
A tour guide explained that no one knew how many tunnels and chambers actually existed underneath Naples. With subways and structural foundations constantly being excavated, new tunnels were found yearly, and some archaeologists speculated that more than thirty miles of tunnels remained undiscovered. Churches and private buildings often refused requests to map out the tunnels underneath them. Tyler had obliquely asked him about the San Lorenzo Maggiore well and whether it connected to the maze that the tourists trod. He told Tyler that he regularly traversed all the known tunnels and had never seen a connection, so the well must lead to one of the still unexplored areas.
The basilica loomed over the tiny Piazza San Gaetano. Like that of most of the other centuries-old churches in downtown Naples, the front door was set back only a few feet from the street. A sign advertised the archaeological excavation under part of the church that had exposed an ancient Greek marketplace.
Though there was no Mass that evening and the archaeological exhibit was closed, the door was wide open to allow worshippers a chance to pray and confess their sins. As the four of them walked in, Tyler mused that the priests would have to be in the confessional a long time to hear all the sins committed by this group.
They bypassed the nave, which was empty of visitors. The well stood in the center of an outdoor courtyard bordered by a cloister. The well opening was topped with a elaborate sculpted frame that was designed to winch the water up in a clay amphora from a pool in the cistern below. The aqueducts had been shut off long ago, so the cistern would now be dry. The well’s frame was now decorated with flowers, hardly the starting point Tyler would ever have imagined for a treasure hunt.
When they were standing at the well, Tyler tried to guess how the spy in the story from Archimedes’ wax tablet wound up here. Had he swum through the tunnels that served as the aqueducts? Tyler pictured the man climbing up the rope that was tied to the winch.
“Show me the mark of Scorpio,” Orr said.
Tyler walked around to the opposite side and pointed inside the well.
The light was fading quickly with the setting sun. Orr played the beam of a flashlight over stones dating from an era hundreds of years before Christ. The marks were just barely visible, fifteen dots carved out of the rock by the spy of Syracuse’s king to identify the location where he intended to return but never did. Tyler had checked the constellations online. The dots matched exactly the arrangement of stars that depicted Scorpio.
“Congratulations, Tyler,” Orr said, while Gaul extracted a rope and climbing gear from the duffel. “I knew this whole mission was a long shot, but you both came through with flying colors.”
Tyler wanted to strangle him right there. “I’m so happy you approve.”
“We’re not done yet. We still need to get down there.”
“We could jump. You go first.”
“Funny,” Orr said, looking around. They were still alone in the courtyard. Tyler didn’t want to find out what Orr would do to someone who innocently stumbled onto them.
Gaul looped the rope around the well’s frame and tested it for strength. It held, so he lowered himself into the well. Three feet down, he hammered a piton into the stone and put a carabiner on it. Gaul tested the metal spike and D-ring to make sure it would hold his weight, then attached a second rope to it.
Tyler understood what he was doing. Both ends of the rope around the frame extended all the way down to the bottom of the cistern. Once the four of them reached the bottom, Gaul would pull one end down and that rope would fall free. That way, no one walking through the courtyard would see the rope attached to the frame and investigate. To climb back up, the second rope would be left attached to the piton and out of sight.
“Okay,” Gaul said. “It’s simple. We’re going to climb down one at a time. I’ll belay you on the way down. Got it?”
They all nodded, and each of them was given a three-belt harness to put on. Tyler put his legs into each of the smaller loops and then buckled the third around his waist. The brake rope was already attached, with the carabiner dangling on the end. Gaul also gave Tyler and Stacy small headband lights that they would use on the climb down.
Gaul went first, his duffel strapped to his back. It took him several minutes to reach the bottom while Tyler and Stacy waited up top with Orr, who stood away from them with his finger ready to trigger the bombs strapped to their waists if he had to. When he was down, Gaul radioed up that he was in place and ready with the Taser.
Stacy went next. Tyler helped her into the well and made sure that her harness was attached properly. She wasn’t tentative about the climb at all. Tyler remembered her talk about exploring ancient ruins and caves with her cameramen in tow, so this descent was nothing new to her. He watched her skillfully climb down until she was out of sight.
For the first time, Tyler was alone with Orr. He stared at Orr, who returned his gaze with his lip curled in a half smile.
“How do you think you and Gaul are going to carry out a hundred and twenty-five tons of gold?” Tyler asked.
Orr laughed quietly. “You think I’m after the gold? I told you. I want the Midas Touch itself.”
“You really are crazy,” Tyler said, shaking his head.
Orr looked as if he was disappointed at Tyler’s skepticism, paused, then said, “Have you ever heard of extremophiles?”
“It sounds like someone who enjoys jumping off buildings wearing a parachute.”
“No. An extremophile is an organism that can exist in conditions that would kill most other life forms. They’re found around volcanic vents on the ocean floor or in acidic hot springs like at Yellowstone Park. They’re microbes called archaea. Some of these microbes have been known to actually digest metals in solution and excrete the solid form. That’s why companies have been trying to mine the ocean floor around these black smokers.”
“And you think that’s what the Midas Touch is?”
“As ridiculous as it sounds, yes. I have researched this my whole life, and that’s my theory. I think Midas’s skin was somehow afflicted with this kind of microbe, perhaps exposed to it during a visit to a hot spring somewhere, but he was immune to its effects. I discovered that many people live with chronic skin diseases. Believe me, you don’t want to see the photos.”
“So how does he turn things to gold?”
“Any object he touched would become contaminated with this microbe. If the object was then submerged in a solution with dissolved gold in it, the object would be transmuted to gold by the microbe.”
“So you think you’ll get rich if you can recover this microbe?” Tyler said. “What makes you think it’s still alive?”
“Over twenty years ago, in that chamber somewhere below us, I saw a man turn to gold in front of my eyes.”
He must have meant the drug runner from Cavano’s childhood tale who chased her and Orr into the chamber. Tyler recalled her saying that the man had touched something inside the golden coffin, something that had caused him excruciating pain. If that was truly the Midas Touch, the king himself may have been immune through some divine providence, but anyone else who came in contact with it would experience mind-bending agony, maybe even death.
“These archaea can remain dormant for thousands of years under the proper conditions,” Orr continued. “Whatever they used to embalm Midas could have preserved the microbe.”
However far-fetched Orr’s theory sounded, he believed it. He almost had Tyler convinced.
“You said the Midas chamber had a pool with a hot spring in it,” Tyler said. “How do you know that’s not the source of this magical ability?”
“I don’t, but I have a way to test it. I have two vials of water with me, one with water containing an acidic mixture of dissolved gold, and another with seawater. If the Midas Touch is real, it will work with those samples as well.”
“Seawater?”
The call came up from Gaul that Stacy had reached the bottom. Orr gestured for Tyler to go next.
As Tyler climbed over the lip of the well and attached his harness, Orr said, “Seawater has minute amounts of gold dissolved in it. If the Midas Touch proves to be as effective as I think it is, you could extract huge quantities of gold from the oceans.”
Tyler’s mind reeled at how much gold that could be. “We’re talking millions of ounces, then.”
Orr shook his head. “You’re thinking way too small. I’ll give you a hint. There are over a billion cubic kilometers of seawater in the world, and the average solubility of gold is thirteen parts per trillion. Now get going.”
Tyler began climbing down. Steadying himself wasn’t too challenging, and the mindless activity allowed him to calculate the staggering sum that was driving this whole venture. Aiden had been far off when he’d guessed that Orr and Cavano were each after a block of gold worth four billion dollars. Tyler went through the math twice and came up with the same stunning figure both times.
If what Orr told him was true, even the most conservative estimate would put the value of all the gold in the world’s oceans at twenty-five trillion dollars.
