temperature water discharge into the cove, so it probably didn’t have a direct link to the explosion.” Austin had brought a plastic bag with him. He opened it and produced the metal cylinder. “We found this floating in the cove. Any idea what it is?”
Contos examined the object and shook his head. “I’ll try to track down the manufacturer when we get back to Washington.”
“Guess your instincts were right, Kurt. Remember, back at Hussong’s, when you said you had the feeling a big bad-assed something was watching us.”
Austin’s coral eyes hardened. “If you’ll remember, I made an other astute observation.”
“What was that?”
“I said that whatever it is lurking in the shadows, the damned thing is as hungry as hell.”
“You two are spooky,” Contos said. “It sounds as if you’re talking about Godzilla.”
Austin said nothing. He stared out at the bow cleaving the waves as if the answers to the questions whirling around in his head could be found beneath the blue-green of the sea.
Chapter 12 THE HAND OF GOD
The airship glided over the rain forest like a huge, elongated Japanese lantern, pulsating with a soft blue- and-orange light as twin tongues of flame from the propane burners heated the air inside the big sausage-shaped envelope. Except for the occasional burner blast, the only evidence of the craft’s existence was a silent shadow that blotted out the moon and stars like a passing cloud.
What Paul and Gamay thought to be a blimp was actually a thermal airship, an ingenious cross between a hot-air balloon and a dirigible. Hot-air burners provided lift, but unlike a balloon, which goes where the wind takes it, the thermal airship had an engine and could be steered under power. The more streamlined zeppelin silhouette had replaced the customary pear-shaped air bag known as the envelope. The envelope kept its shape with internal air pressure instead of a rigid blimp skeleton.
The Trouts sat side-by-side at the front of the aluminum frame gondola, held in their comfortable padded seats by full harnesses. From their perspective, slung under the belly of the envelope, the blimp looked enormous. The polyester fabric bag was one hundred feet long and half that in height. It had a full rudder at the back end for steering and large, thick fins for stability. Behind the passenger seats were the propane tanks that fueled the burners, the fuel containers for the Rotex two-stroke power plant, the engine itself, and the three-blade propeller that provided lateral thrust.
Paul and Gamay had taken turns acquainting themselves with the airship’s controls. Both Trouts had ridden in balloons and knew the principles of hot air. The airship’s operation was relatively simple. A foot-operated valve controlled the stainless steel burners that kept hot air flowing through a metal chute into the envelope. The instrument panel had only half a dozen gauges. The Trouts watched the altimeter with gimlet eyes, keeping the airship at about two thousand feet, an altitude that would give them a reasonable safety margin.
Keeping the airship aloft had drained the propane from one tank, and they were operating on reserve. They had been waiting for daylight to use the power plant, so a plentiful fuel supply remained for the propeller drive. A pearl-gray glow in the east announced the coming of dawn. Soon the sky turned rose-petal pink. Even after the sun rose the visibility was obscured by fog. The vapors rising off the tree canopy absorbed the sky’s hue, and a roiling, reddish sea of mist stretched off to the horizon. While Paul operated the airship Gamay rummaged around in a storage box between the two seats. “Time for breakfast,” she announced cheerfully.
“I’ll have mine over easy,” Paul replied. “Crisp on the bacon, please, and the home fries burned around the edges.”
Gamay offered Paul a choice of granola bars. “You can have raspberry or blueberry.”
“I’ll try room service.” He flicked on the radio, but all they heard was the crackle of static. “Bet Phineas Fogg never had to rough it like this,” Paul said with a frown. “Aw hell, I’ll take blue berry.”
She handed him a bar and a bottle of warm mineral water. “That was quite a night.”
“Yes, I would say that having a brush with ruthless bio pirates, witnessing a cold-blooded murder, and escaping from savage Indians would certainly qualify as quite a night.”
“We owe our lives to Tessa. I wonder how she got hooked up with Dieter.”
“She’s not the first woman to show poor judgment in men. If you had married a lawyer or a doctor instead of a fisherman’s son, you would be floating in your backyard pool instead of being up here.”
“How boring.” Gamay chewed thoughtfully on her breakfast bar. “Any idea where we are, Mr. Fisherman’s Son?”
He shook his head. “I wish my dad were here. He learned how to navigate the old-fashioned way before we started to depend on electronic gear.”
“What about the compass?”
“Not much use unless you’ve got landmarks or navigational buoys to go with it. That’s obviously east.” He pointed to the sun.
“The Dutchman’s settlement was south and west of Ramirez,” Gamay said. “What if we aimed this thing north east?”
Paul scratched his head. “That might work if we were sure we were still at the exact spot where we climbed into this rig. There was a breeze last night. I don’t know how far it could have pushed us. Could make a big difference, and we’ve only got a limited amount of fuel left for the burners. Any decision will have to be the right one. The engine tanks are full, but it won’t do much good to go forward if we lose altitude.”
Gamay gazed over the ocean of green. “Sure is beautiful.”
“Not as beautiful as three eggs over easy and bacon with home fries.”
She handed him another granola bar. “Use your imagination.”
“I am. I’m trying to imagine how they got this airship into the forest. They could have flown it in, but that’s doubtful be cause this isn’t big enough to carry all the supplies and spare fuel it would need. My guess is they launched it from the ground not far from where we found it.”
“Since there are no roads,” Gamay said, picking up the thread of logic, “they probably came in by water. If we found the river or tributary we could retrace our way back to Dr. Ramirez’s camp. Perhaps if we went higher, we’d see more of the forest.”
“Brilliant,” he said, and goosed the throttle with his foot.
The burners responded with a throaty whisper, and after a pause the aircraft began to rise. As they ascended, the heat of the sun was beginning to burn off the mist. The tree canopy began to appear as ragged patches of green. Reddish flowers grew in patches on the treetops like coral reefs.
At three thousand feet Gamay squinted through the haze. “I see something over there.”
Paul started the power plant and turned the steering wheel that controlled the cables running to the rudder until the airship came slowly about. With the water-cooled engine purring quietly, the airship gained speed slowly as it overcame its inertia, and before long the propeller was kicking them along at ten miles per hour. Gamay had found a pair of binoculars and was using them to scope out where they were going.
“Incredible,” she said as the mists cleared.
“What do you see?”
Gamay was silent for a second. “The Hand of God,” she said with quiet awe.
Paul hesitated. He hadn’t slept much and was slow on the uptake. “The Great Falls the Dutchman talked about?”
Gamay nodded. “Even at this distance it’s magnificent.”
Paul tried to increase their speed. He sensed something peculiar about the controls. The airship seemed to be dragging. He peered down and saw a red triangular object dangling from lines attached to the gondola.
“Hello,” he said. “We’ve got company.”
Gamay lowered the binoculars and followed Paul’s gaze. “It looks vaguely like a life raft. Made out of rubber tubing and mesh in the middle. They probably used it to drop people and supplies off on the tree canopy.”
“Sounds like a reasonable explanation. We’ll have to be careful it doesn’t catch in the treetops.” He lifted his head to check on their course. What he saw sent chills up his spine.
They were approaching a high headland that rose from the forest in the shape of a giant step. A river coursed from the forest toward the precipice of the plateau where rocky formations broke the flow into five waterfalls. With the sunlight sparkling off the white water the streams looked like gems being run through the fingers of a diamond merchant. The falls had the deceptive slow-motion look that water has when it plunges from a great height. A thick
