Ralph finally obeyed, rolling to his back.

Norman swam at his side, one hand snarled in the neck of Ralph’s shirt, keeping the man’s head above water. As the two drifted away, Norman admonished the big man with one final warning. “Keep tight to that case,” he sputtered. “Lose my cameras, and I’ll let you drown!”

“We’re next,” Sam said, shoving his Stetson into his pack. “You ready?”

Maggie took a deep breath and nodded.

“You gonna be okay?” he said, straightening and meeting her eyes.

Maggie knew he was referring to her panic attacks more than the threat from the water. “It was my idea, wasn’t it? I’ll be fine.”

“You first then,” he said.

She opened her mouth to argue when she felt a tickle on her leg. Glancing down, she saw a tarantula as large as a fist climbing up her khakis. Gasping in disgust, she knocked it away with her flashlight. Raising Gil’s snub-nosed rifle above her head, she jumped gracelessly into the water.

Her back and bottom crashed into the water with a resounding splash. The brief sting of the impact was immediately replaced with lung-constricting cold. Her head burst above the water with a silent scream of shock. All her muscles cramped tight. She had to force her limbs to move. The cold burned through her clothes and froze the breath in her lungs.

Sam splashed just behind her.

Before she could turn or speak, the current grabbed her and started sweeping her down the channel. Maggie floated on her back, legs thrust before her so she could bounce off any unseen obstacles. She kept the flashlight above the water and used the stock of the rifle as a paddle to help her stay afloat.

Just at the edge of her light’s reach, she saw Norman and Ralph disappearing down the throat of the river tunnel.

Sam called to her. “How you holding up?”

Maggie frowned. Now was not the time for a conversation. She spat out a mouthful of cold water after a sudden splash had caught her by surprise. The icy water froze even the fillings in her mouth. “Fine!” she sputtered.

Then the current dragged her into the black maw of the tunnel. The low roof flew by overhead, low enough that the tip of the rifle dragged along the rock above. Small sparks spat out where steel and rock rubbed. The scraping sound was eerily loud in the tight space.

Just as suddenly they were out of the tunnel and into the bat cave. Maggie’s eyes instantly stung; her nose burned. Overhead, circling bats dove and glided through the edge of the flashlight’s beam, still disturbed and wary of the two-legged intruders. A small sliver of sunlight lightened one corner of the arched roof. The bat’s doorway. Too high and too small to do them any good.

But Maggie had little time for sight-seeing. The current had grown even swifter through this chamber, a mixed blessing. Though the swift waters churned a cloud of mist that washed away the worst of the guano fumes, the faster waters also frothed and tossed her body more vigorously.

Maggie’s limbs grew leaden as the cold tried to freeze the marrow of her bones. Breathing became laborious. She gave up trying to keep the rifle above water and used it as a rudder to keep her from bouncing too hard against the jagged rocks on either side. She concentrated on just keeping the flashlight pointed forward.

Now nearly blind from the fumes and with her nose on fire, Maggie gasped and choked. Something suddenly scrabbled at her upraised arm, weighting it down, digging at her skin. Blinking, Maggie saw a huge bat perched on her arm, tiny claws scratching at her, leathered wings batting wildly. Sharp fangs glinted in the glow of the flashlight. She let out a strangled gasp. Wide eyes and huge ears swung toward the sound. Crying out, she shoved her arm underwater, taking her chances that the flashlight was insulated enough to take a short dunk. She was in luck; the flashlight shone brightly under the water, and the shock of the cold stream dislodged the bat.

It rolled through the water, bumping against her shoulder as it passed.

Maggie lifted the flashlight from the water, paddling fiercely.

Then the bat was on her again. Maggie felt a small tug on her hair trailing in the water. Like a hooked fish, the bat had snatched at this purchase. Now twisting and rolling, it climbed the tangled strands. Maggie felt tiny claws scratch at her scalp. The bat screeched wildly, almost in her ear.

The creature’s distress call was answered from above. The cavern erupted with squeaks and supersonic piping, like fingernails dragged across a blackboard. Overhead, the roof seemed to drop lower as the entire massed colony took flight, diving toward the screeching bat tangled in Maggie’s hair.

Oh, God! She beat at the winged creature with her flashlight, trying to club it away, but only succeeded in snarling it further. Claws ripped across her cold cheek, a line of fire.

Suddenly a hand appeared, pushing back her flashlight. “Hold still!”

It was Sam. He grabbed the squirming bat and ripped it from its nest in her hair, tearing out hundreds of roots along with the foul creature. He tossed it away. The bat hit the far bank with a wet smack.

“Here they come!” Sam yelled.

Maggie barely had time to see the dark cloud descend toward them, and even less time to take a breath, before Sam shoved her head underwater. Maggie would have panicked, but Sam held tight to her, his body close to hers, his touch the only warmth in the icy stream. She released control to him, letting him carry her as she held her trapped breath.

Soon the channel straightened, and the current grew swift and smooth. Maggie risked opening her eyes. The flashlight still glowed under the water, illuminating Sam’s face. His blond hair, normally plastered under his Stetson, wove like fine kelp across his face. His eyes met hers. She drew strength from his solid gaze. He pulled her tighter to him. She didn’t resist.

The current dragged them swiftly away, tumbling them to and fro. Maggie’s lungs cried for air. Unable to hold out any longer, she wiggled slightly from Sam’s grasp and pushed toward the surface. She would only risk a quick breath.

As her head popped from the water, she gulped air into her frozen lungs. She was ready to duck back down, when she noticed two things—the air had cleared of the burning sting and just ahead a small purplish glow lit the left bank.

Sam surfaced beside her with a whoosh of expelled air.

Maggie lifted her flashlight and pointed. “There!”

Sam twisted around. As they neared the site, Maggie spotted Norman helping Ralph from the water. The huge football player crawled on hands and knees. Atop the bank, Denal was limned in the eerie light of the Wood’s lamp. His teeth shone a whitish purple as he waved the lamp overhead, signaling to them.

Together, Maggie and Sam kicked toward the shore, but they didn’t have to struggle far. The channel curved with a deep natural eddy at the bend. The current tossed Maggie and Sam into the sluggish pocket. With limbs deadened by cold and clothes waterlogged, it was an effort to climb from the water. Like Ralph, Maggie found herself crawling onto the bank and collapsing on her back.

Sam threw himself across the rock beside her, tossing his Winchester up higher on the stony bank. “So much for keeping the guns dry.”

Norman stepped beside Maggie. His teeth chattered as he spoke. “Y… you both need to keep moving. And… and get out of those wet clothes.” He tugged off his own soaked shirt.

Maggie noticed Denal had already stripped to his skivvies, and Ralph was slowly kicking off his clinging pants.

“We’re not out of danger yet,” Norman continued. “That water was near freezing. We’ll die unless we can get dry and warm.”

Maggie found her limbs beginning to tremble. Sam glanced at her. “It’s j… just the cold,” she said, knowing what he was thinking.

“Up with the both of you,” Norman said sternly.

Groaning, Sam pushed up as the photographer offered Maggie his arm. Too exhausted to object, she took Norman’s hand and let him help her to her feet.

“Now strip,” he said.

Maggie’s fingers were numb and blue in the flashlight beam. She fumbled at her buttons and shrugged out of her shirt, too cold and exhausted to worry about exposing herself. Hell, she thought, yanking her zipper down, a good blush would be welcome right now.

Soon she stood in nothing but her wet bra and panties.

The others kept their eyes politely turned, except Denal who stared widely at her. Once the boy realized he was caught gaping, he quickly looked away.

Maggie scowled to cover her grin. She slapped Sam on his damp boxers as she stepped past him. “Norman says to keep moving. We have to stay warm.”

Maggie could feel Sam’s eyes on her back as she moved away. The Texan mumbled behind her, “Oh, don’t worry. Keep walking ahead of me dressed like that, and I’ll be plenty warm.”

This time she couldn’t hide her smile.

“Th… this must lead somewhere,” Sam said, trying to control his chattering teeth, as he pointed out the gold path that continued along the river.

No one answered, busy as they were shivering and rubbing frigid limbs. The icy water had lowered everyone’s core body temperature and, with no way to start a fire, they were all at risk of hypothermia. They needed to find a dry, warm place… and soon.

Sam, who had moved ahead of them, suddenly called out. With his flashlight pointed over a rise in the trail, Sam’s half-naked form was striking, limned in the back glow. Maggie had not realized just how fine a physique her fellow colleague had hidden under his baggy clothes. From broad shoulders down to his narrow waist and strong legs, Sam struck a handsome pose.

“Come see this!” Sam exclaimed, a broad grin on his face.

Maggie saw Norman grab for his camera case as she climbed to join the others.

Before her, spreading across a cavern as large as her university’s soccer stadium, was a small dark city. Sam’s light was the only source of illumination, but its dim glow was enough to light up the entire chamber. Houses of brick, some three stories high, dotted the floor, while up the walls climbed tier after tier of stacked granite homes, like a jumble of toy blocks. Empty windows stared back at them. Throughout the city, brighter splashes of gold and silver decorated many of the abodes. But what caught all their eyes was what stood in the town’s center. Across the chamber, a massive gold statue stretched toward the ceiling, towering over the buildings. It was similar to the one that guarded the entrance to the cavern, but it was too distant and dark to make out any details.
