Excavation (18 page)

The remainder of the long morning stretched into an endless hike, mostly at a steady incline. Legs and backs protested as the cavern system led them higher inside the Andean mountain. If not for the lack of food and the growing exhaustion, Sam might have better appreciated the sights: towering stalagmites, cavernous chambers with limpid pools that glowed with a soft phosphorescence, cataracts that misted the gold trail at times with a welcome cooling spray, even a side cave so festooned with lacy crystals
that it looked as if the chamber was full of cotton candy. It was a wonderland of natural beauty.

And everywhere they went, the carved pillars marked their way as grim sentinels, watching the group pass with unblinking silver eyes.

But as amazing as the sights were, the memory of what lay behind them never fully vanished. Breaks to drink from the stream were often accompanied by worried glances toward the rear. So far there had been no sign of pursuit by the tarantula army. It seemed they had left the spiders far behind.

Slowly, the morning wound to afternoon. The only highlight was a brief lunch to split a pair of Milky Way bars found stashed in Norman's camera case. Chocolate had never tasted so good. But even this small taste of heaven was short-lived, and only succeeded in amplifying everyone's hunger. Tempers began to grow short and attitudes sullen as they marched through the afternoon.

To make matters worse, a sharp pungency began to fill the cavern's normally crisp air. Noses wrinkled. “Ammonia. Smells like the ass end of a skunk,” Sam commented.

“Maybe the air is going bad,” Norman said with a worried expression on his haggard face.

“Don't be a fool,” Ralph snapped. “The air would have been worse when we were deeper.”

“Not necessarily,” Maggie said. Her eyes had narrowed suspiciously, squinting at the darkness beyond the light. “Not if there was a source giving off the noxious fumes.”

Ralph still scowled, clearly tired and irritated. “What do you mean?”

Instead of answering, Maggie turned to Sam. “All those tarantulas. From the look of them, they were well fed. What do the feckin' things eat down here?”

Sam shook his head. He had no answer.

“Oh God!” This came from Norman, who had taken the lead with the flashlight. The gold path led over a short rise into a neighboring cavern. From the echo of his exclamation, the chamber was large.

The others hurried to join him.

Maggie stared at the scene ahead, holding a hand over her mouth and nose. The sting burned their eyes and noses. “There's the answer. The source of the tarantulas' diet.”

Sam groaned. “Bats.”

Across the roof of the next cave, thousands of black and brown bats hung from latched toes, wings tight to bodies. The juveniles, squirming among the adults, were a paler shade, almost a coppery hue. Sharp squeaks and subsonic screeches spread the warning of intruders across the legion of winged vermin. Hundreds dropped from their perches to take flight, skirting through the air.

The source of the odor was immediately clear.

“Shit,” Ralph swore.

“Exactly,” Norman commented sullenly. “
Bat
shit.”

The floor of the cavern was thick with it. Carved pillars, fouled with excrement, speared upward through the odorous mess. The reek from the aged droppings was thick enough to drive them all back with a stinging slap.

Norman tumbled away, choking and spitting. Bent at the waist, he leaned on his knees, gagging.

Ralph looked as if his dark skin had been bleached by the corrosive exposure. “We can't cross here,” he said. “We'd be dead before we reached the other side.”

“Not without gas masks,” Maggie agreed.

Sam was not going to argue. He could barely see, his eyes were watering so fiercely. “Wh…what are we going to do then?”

Denal spoke up. He had hung back from the cavern's opening and so had borne the least of the exposure. Even now, he was not facing ahead, but behind. He had an arm pointed. “They come again.”

Sam turned, blinking away the last of the burn. He took the flashlight from the incapacitated Norman. Several yards down the gold trail, three or four white bodies scurried across the rocky landscape. Scouts of the tarantula army.

“To hell with this,” Ralph said, voicing all their concerns.

“What now?” Maggie asked.

Sam glanced forward and backward. Everyone began talking at once. Sam raised the light to get everyone's attention. “Stay calm! It won't do us any good to panic!”

At that moment, Sam's flashlight flickered and died. Darkness swallowed them up, a blackness so deep it seemed as if the world had completely vanished. Voices immediately dropped silent.

After a long held breath, Norman spoke from the darkness. “Okay, now can we panic?”

 

Joan ushered Henry into her lab. “Please make yourself at home,” she offered, then glanced at her wristwatch. “Dr. Kirkpatrick should be here at noon.”

Behind her, Henry had paused in the dooway to her suite of labs, his eyes wide. “It's like a big toy store in here. You've done well since our years at Rice.”

She hid a smile of satisfaction.

Slowly, Henry wandered further into the laboratory, his gaze drifting over the plethora of equipment. Various diagnostic and research devices lined the back of the room: ultracentrifuge, hematology and chemistry analyzer, mass spectrograph, chromatograph, a gene sequencer. Along one wall was a safety hood for handling hazardous substances; along the other stood cabinets, incubators, and a huge refrigerated unit.

Henry walked along the row of machines and glanced into a neighboring room. “My God, you even have your own electron microscope.” Henry rolled his eyes at her. “To book any time on our university's, it takes at least a week's notice.”

“No need for that here. Today, my lab is at your full disposal.”

Henry crossed to a central U-shaped worktable and set down his leather briefcase, his eyes still drifting appreciatively around the room. “I've had dreams like this…”

Chuckling to herself, Joan stepped to a locked stainless-steel
cabinet, keyed it open and, with two hands, extracted a large beaker. “Here's all the material we collected from the walls and floor of the radiology lab.”

She saw Henry's eyes widen as she placed the jar before him. He leaned over a bit, pushing his glasses higher on his nose. “I didn't realize there was so much,” he said. The yellowish substance filled half of the liter-sized beaker. It shone brightly under the room's fluorescent lights.

Joan pulled up a stool. “From the amount, I judge it must have filled the skull's entire cranium.”

Henry picked the beaker up. Joan noticed that he quickly grabbed it with his other hand. The stuff was heavier than it appeared. He tilted the jar, but the unknown substance refused to flow. Replacing the beaker on the table, he commented, “It looks solid.”

Joan shook her head. “It's not.” She grabbed a glass rod and thrust it into the material. It sank but not without some effort, like pushing through soft clay. Joan released the rod, and it remained standing straight in the jar. “Malleable, but not solid.”

Henry tried to move the glass rod. “Hmm…definitely not gold. But the hue and brilliance are a perfect match. Maybe you were right before, a new amalgam or something. I've certainly never seen anything like it.”

Joan glanced at him, eyebrows raised. “Or maybe you have. Let's compare it to the gold cross. You brought it with you, yes?”

He nodded. Twisting back to the table, Henry dialed the lock on his briefcase and snapped it open. “I figure it's safer with me than at the hotel.” He removed the ornate Dominican cross and held it toward her.

The workmanship was incredible. The Christ figure lay stretched and stylized upon a scrolled cross; the pain of his agony sculpted in the strain of his limbs, yet his face was full of passionate grace. “Impressive,” she said.

“And solid…so I doubt it's made of the same amalgam.” Henry placed the crucifix beside the beaker. The
strange material and the cross glinted and shone equally.

“Are you sure?”

Henry met her eyes over the rim of his spectacles. He shrugged his brows. “I'll leave the final assessment to your expert.”

She reached for the crucifix. “May I?”

“Of course, Joan.”

Her hand hesitated for a heartbeat when Henry used her name. The intimacy and surroundings brought back sudden memories of when the two were lab partners during a semester in undergraduate biology. How strange and vivid that recollection was at the moment. More than just déjà vu.

Without meeting his eye, Joan took the cross from the table. The past was the past. She hefted the crucifix in her palm. It, too, weighed more than it appeared—but didn't gold always seem that way? She held the crucifix up to the light, tilting it one way, then the other, studying it.

Henry theorized aloud while she examined the relic. “It's definitely the work of a Spanish craftsman. Not Incan work. If the cross is confirmed to be composed of the same amalgam, then we'll know for sure the Spanish brought the substance to the New World, rather than the other way around…”

He continued talking, but something had caught Joan's attention. Her fingers felt small scratches on the crucifix's back surface. She reached to a pocket and slipped out her reading glasses. Putting them on, she turned the crucifix over and squinted. It was not the artist's signature or some piece of archaic scripture. Instead it seemed to be row after row of fine marks. They covered the entire surface of the crucifix's back side.

“What is this?” Joan asked, interrupting Henry.

He moved closer, shoulder to shoulder with her. Joan noticed the faint scent of him, a mix of aftershave and a richer muskiness. She tried to ignore it.

“What are you talking about?” he asked.

“Here.” With a fingernail, she pointed to the marks.

“Ah, I noticed those. I think they're a result of the cross rubbing against the friar's robe, slowly abrading the soft gold over the years.”

“Mmm, maybe…but they seem too symmetrical, and some of the marks are quite deep and irregular.” She turned slightly to Henry, almost nose to nose. His breath was on her cheek, his eyes staring deep into hers.

“What are you suggesting?”

She shook her head, stepping away. “I don't know. I'd like to get a closer look.”

“How?”

Joan led him around the corner of the table where sets of microscopes were positioned. She moved to a bulky binocular unit with a large glass tray under it. “A dissection microscope. Normally I use it to study gross tissues more closely.”

She placed the cross facedown on the tray and switched on the light source. Illuminated from above, the gold glowed with an inner fire. Joan adjusted the light so it shone obliquely across the crucifix. Bending over the eyepiece, she made fine adjustments in the lenses. Under the low magnification, the surface of the cross filled the view. The marks on the crucifix were in stark relief, appearing as deep gouges in the metal, long valleys, clearly precise and uniform. The scratches composed a series of repeated tiny symbols: rough squares, crude circles, horizontal and vertical squiggles, hash marks, nested ovals.

“Take a look,” Joan said, moving aside.

Henry bent over the scope. He stared a few moments in silence, then a low whistle escaped his lips. “You're right. These are not random scratches.” His gaze flicked toward her. “I think there's even silver embedded in some of the grooves. Perhaps traces of the tool used to scratch these marks.”

“For such painstaking work, there must be some reason to go through all that effort.”

“But why?” Henry's lips tightened as he pondered this new mystery, his eyes slightly narrowed. Finally, he expelled a breath. “It may be a message. But who knows for sure? Maybe it's just an ordinary prayer. Some benediction.”

“But in code? And why on the back of the cross? It must mean something more.”

Henry shrugged. “If the friar notched it as a message while imprisoned, it may have been the only way he could keep it secure. The Incas revered gold items. If the cross was with him when he died on the altar, the Incas would have kept the crucifix with the body.”

“If you're right, who was his message meant for?”

Henry shook his head slowly, his gaze thoughtful. “The answer may lie in this code.”

Joan moved back to the scope. She slid a legal pad and a pen from a drawer, then sat down and positioned herself to copy the marks on her paper. “Let's check it out. I've always liked dabbling with cryptograms. If I don't have any luck, I can also run it by someone in the computer department, pass it through a decryption program. They may be able to crack it.”

Henry stood behind her as she recorded the writing. “You've grown into a woman of many talents, Dr. Joan Engel.”

Joan hid her blush as she concentrated on her task, copying the marks carefully. She worked quickly and efficiently, not needing to look up as she jotted what she saw. After years of making notes while studying a patient's sample under a microscope, she had grown skilled at writing blind.

In five minutes, a copy lay on the table beside her. Row after row of symbols lined the yellow paper. She straightened from her crouch, stretching a kink from her neck.

“Hold still,” Henry said behind her. He slid a hand along her shoulder and gently lifted the cascade of hair from the back of her neck. His knuckles brushed her skin.

She suppressed a shiver. “Henry…?”

“Don't move.” His fingers reached to knead the muscles of her strained upper shoulders. At first, his skin was cool against her own, but as he worked, heat built under his strong fingers, warming her sore muscles.

“I see you've not lost your touch.” She leaned into his fingers, remembering another time, another place. “So if I tell you to stop, ignore me,” she said, feigning a nonchalance that the huskiness of her voice betrayed.
