While Giordino was concentrating on their prisoners, Pitt removed a large nylon net bag from his weight belt and opened the metal clasp at the top. He stared at the sinister black skull that seemed to stare back through empty eye sockets. He could not help but wonder if a curse came with the skull. What cryptic secrets did it hold?
Pitt's idealistic nature was overpowered by his practical side. Though he was a daydreamer, he did not buy into myths and folktale. If an object or conception could not be seen, felt, or experienced, it did not exist for him. If he wasn't already a hundred and eighty feet under water, he would have spat in the eye of the obsidian skull. But because it was a link in a chain of enigmas, he was determined to place it in the hands of people who could properly study it.
"Sorry, my friend," he murmured so softly that Giordino didn't hear him, "but it's time you revealed yourself." He lifted the skull very carefully from its pedestal and slid it into the carry bag. At this depth he handled it easily, but once it carne out of the water, he guessed it would weigh a solid forty pounds. He took one final look at the chamber, the inscriptions on the walls, the still-burning floodlights lying on the floor where they had been hurled during the struggle. Then he dove headfirst through the hole in the rock, mindful not to knock the skull against the rock and shatter it. Giordino had already pulled the two divers into the tunnel. The giant of a man had regained consciousness and was struggling violently to break free of the electrical cord that bound his ankles and pinned his arms tightly against his immense body.
"Need a hand?" Pitt asked.
"You carry the skull and the bag with the cameras. I'll tote the refuse."
"Best if you go first and I follow. That way I can watch them every inch of the way in case Big Boy starts breaking loose."
Giordino handed him the little gun with the barb. "Shoot him in his Adam's apple if he so much as wiggles a finger."
"We'll have to be very careful in our decompression stops. We may not have enough air for the four of us."
Giordino made an indifferent motion with his hands. "Sorry, I'm not in a sacrificial mood."
The return went slowly. Giordino made better time dragging the two divers and their breathing gear by walking over the ore track ties than trying to swim his way back to the shaft. Precious air was lost during the prolonged passage. Pitt kept a close eye on his air gauge- he knew that his air was seriously depleted. The gauge read just three hundred pounds. He and Giordino had used twice the amount of air they had computed before the dive, not having counted on a fight with intruders.
He curled his body and kicked around to the side of the bound divers, checking their air gauges. Both men had nearly seven hundred pounds. They must have found a shorter route through the mine to the chamber, Pitt surmised. After what seemed a year and a day, they finally reached the vertical shaft and rose to the first decompression stop. Sheriff Eagan and Luis Marquez had lowered two spare tanks on nylon line to the precise depth Giordino had calculated earlier.
Keeping a tight eye on his decompression computer, Giordino listened as Pitt read off the air pressure remaining in each tank. Only when they went beyond the safety level did he unstrap and push them aside. The prisoners did not become belligerent. They'd come to realize that to resist was to die. But Pitt didn't let down his guard for a second. He knew well they were two ticking time bombs, waiting to explode at the first opportunity that presented itself for them to escape.
Time passed as if mired in glue. They used up the last of their air and went on the reserve tanks. When the prisoner's tanks were dry, Pitt and Giordino began to buddy-breathe with them, exchanging their mouthpieces between breaths. After the prescribed wait, they lazily swam up to the next decompression stop.
They were scraping the bottom of the reserve tanks when Giordino finally gave the "surface" sign and said, "The party's over. We can go home now."
Pitt climbed the rope ladder thrown into the shaft by Marquez. He reached the rim of the tunnel floor and handed Sheriff Eagan his air tanks. Then he passed up the skull and camera bag. Next, Eagan took Pitt's outstretched hand and helped him onto firm rock. Pitt rolled over on his back, removed his full face mask, and lay there for a minute, thankfully breathing in the cool damp air of the mine.
"Welcome home," said Eagan. "What took you so long? You were due back twenty minutes ago."
"We ran into two more candidates for your jail."
Giordino surfaced, climbed up, and then knelt on his hands and knees before hauling the smaller prisoner into the tunnel. "I'll need help with the other," he said, lifting his face mask. "He weighs two of me put together."
Three minutes later, Eagan was standing over the intruders, questioning them. But they glared menacingly at him and said nothing. Pitt dropped to his knees and removed the dive hood covering the smaller man's head and chin.
"Well, well, my friend the biker. How's your neck?"
The constrained killer lifted his head and spat at Pitt's face, narrowly missing. The teeth were bared like a rabid dog's. Eyes that had seen more than one death glared at Pitt.
"A testy little devil, aren't we?" said Pitt. "A zealot of the Fourth Empire. Is that it? You can dream about it while you rot in jail."
The sheriff reached down and gripped Pitt's shoulder. "I'll have to let them go free."
Pitt stared up, his green eyes suddenly blazing. "Like hell you will."
"I can't arrest them unless they've committed a crime," Eagan said helplessly.
"I'll press charges," Marquez cut in coldly.
"What charges?"
"Trespassing, claim-jumping, destroying private property, and you can throw in theft for good measure."
"What did they steal?" Eagan asked, puzzled.
"My overhead lighting system," Marquez replied indignantly, pointing down at the electrical cord binding the divers. "They've snatched it from my mine."
Pitt placed a hand on Eagan's shoulder. "Sheriff, we're also talking attempted murder here. I think it might be wise if you held them in custody for a few days, at least until a preliminary investigation can make an identification and perhaps uncover evidence of their intentions."
"Come on, Jim," said Marquez, "you can at least keep them under lock and key while you interrogate them."
"I doubt whether I'll get much out of this lot."
"I agree," said Giordino, running a small brush through his curly hair. "They don't look like happy campers."
"There's something going on here that goes far beyond San Miguel County." Pitt peeled off his dry suit and began dressing in his street clothing. "It won't hurt to cover your bases."
Eagan looked thoughtful. "All right, I'll send a report to the Colorado Investigation Agency-"
The sheriff broke off as every head turned and stared up the tunnel. A man was shouting and running toward them as if chased by demons. A few seconds later, they could see that it was one of Eagan's deputies. He staggered to a halt and leaned over until his head was even with his hips, panting for breath, exhausted after running from the hotel wine cellar.
"What is it, Charlie?" Eagan pressed. "Spit it out!"
"The bodies…" Charlie the deputy gasped. "The bodies in the morgue!"
Eagan took Charlie by the shoulders and gently raised him upright. "What about the bodies?"
"They're missing."
"What are you talking about?"
"The coroner says they've disappeared. Somebody snatched them from the morgue."
Pitt looked at Eagan for a long moment of silence, then said quietly, "If I were you, Sheriff, I'd send copies of your report to the FBI and the Justice Department. This thing goes far deeper than any of us imagined."
