Feeling as if he had survived a roller-coaster ride, Pitt returned inside, retrieved the topographical map and began studying the twists and turns in the river as well as familiarizing himself with the network of swampy bayous and lakes between Wheeler's Landing and the canal dug by Qin Shang Maritime. He traced and compared the landmarks and river bends with those on the map. It was refreshing to sit comfortably in the shade of the veranda overhang and experience the pleasant sensation of traveling smoothly over timeless waters that only a boat can provide. Riverbank vegetation varied from mile to mile. Thick forests with willows, cottonwoods and cypresses interspersed with berry bushes, and wild grapevines slowly gave way to a moist, primeval swamp, a prairie of soaring reeds swaying under a light breeze that swept off to the horizon. A lone cypress rose majestically out of the grass like a frigate on the sea. He saw herons walking on their long, sticklike legs along the fringe of water, their necks bent into an S shape as they pecked for food in the mud.

To a hunter kayaking or paddling a canoe through the swamps of southern Louisiana, the trick was to find a firm piece of ground on which to pitch a tent for the night. Duckweed and hyacinth floated on much of the open water. Forests grew from the brackish muck, not dry land. It was hard for Pitt to imagine that all the water he could see came from as far away as Ontario and Manitoba, North Dakota and Minnesota, and every state below. Only behind the safety of thousands of miles of levee systems did people cultivate farms and build cities and towns. It was a landscape unlike any he'd ever seen.

The day was pleasantly cool, with just enough breeze to make small waves across the surface of the water. The hours rolled by as if time was as limitless as space. As idyllic as the lazy cruise up the river seemed, they were on serious business that could easily be the cause of their deaths. There could be no mistakes, no errors in planning their reconnaissance of the mysterious canal.

A few minutes after noon, Pitt took a salami sandwich and a bottle of beer up to Giordino in the little wheelhouse on the roof. Pitt offered to take the helm, but Giordino wouldn't hear of it. He was having too much fun, so Pitt returned to his chair on the veranda.

Although time seemed to have no meaning, Pitt's hours were neither idle nor aimless. He spent the time laying out their diving equipment. He unpacked and adjusted the controls on the little AUV he had used at Orion Lake. Lastly, he removed the night-vision goggles from their case and laid them on the cushions of an old, worn sofa.

Shortly after five o'clock in the afternoon, Pitt stepped inside the house and stood at the base of the ladder leading up to the pilothouse on the roof. "One half mile before we reach the mouth of the canal," he alerted Giordino. "Move on past another half mile to the next bayou. Then swing a turn to starboard."

"What's it called?" asked Giordino.

"Hooker's Bayou, but don't bother looking for a sign at the intersection. Take it for about six miles to where the map shows an abandoned dock by a capped oil well. We'll tie up there and have dinner while we wait for darkness."

Giordino eased the shantyboat around a long string of barges pushed downriver by a large towboat. The captain of the towboat gave a blast from his air horn as they passed, no doubt thinking the owner was on board the shantyboat. Pitt had returned to his chair on the bow and waved. Using a pair of binoculars, he scrutinized the canal as they crossed its mouth. It was carved in a perfectly straight course nearly a quarter of a mile wide that seemed to roll like a green carpet over the horizon. A rusty chain stretched across the mouth and was attached to concrete pilings. Large, billboard-sized signs were raised with red letters against a background of white that said, NO TRESPASSING. ANYONE CAUGHT ON QIN SHANG MARITIME PROPERTY WILL BE PROSECUTED.

Small wonder the local residents hate Qin Shang, thought Pitt. He seriously doubted that the local sheriff would go out of his way to arrest friends and neighbors for hunting or fishing on foreign-owned property.

Forty minutes later, Giordino eased back on the throttle and swung the bulky shantyboat from the narrow channel of Hooker's Bayou and crept to a halt toward the remains of a concrete pier, nudging the flat, raked bow onto a low bank. Stenciled lettering on the concrete pilings read, CHEROKEE OIL COMPANY, BATON ROUGE, LOUISIANA. The boat had no anchor, so they took up long poles that were tied to the catwalks for the purpose and rammed them into the mud. Then they tied the mooring lines from the boat to the poles. Lastly, a gangplank was run out onto firm ground.

"I have a contact on radar moving across the marsh from the southeast," Giordino calmly reported.

"They're coming from the direction of the Mystic Canal."

"They're coming fast," Giordino said in a deliberate tone.

"Shang's security didn't waste any time tagging us." Pitt went ins

ide and returned with a large square net with vertical supports he'd found on the aft veranda. "Drag Romberg out here and get yourself a bottle of beer."

Giordino looked at the net. "You think you're going to catch crab for dinner?"

"No," Pitt answered, catching a glint from the setting sun on a shiny object far away in the ocean of grass. "The trick is to look like I know what I'm doing."

"A helicopter," Giordino said in a deliberate tone, "or an ultralight like Washington."

"Too low, more likely a hovercraft."

"Are we on Qin Shang's real estate?"

"According to the map, we're a good three hundred yards off their property line. They must be paying a social call to check us out."

"What's the scenario?" asked Giordino.

"I'll play a crab fisherman, you act like a redneck swilling beer and Romberg can play Romberg."

"Not easy for an Italian to pretend he's French Cajun."

"Chew on some okra."

The dog cooperated when dragged out onto the veranda, not out of obedience, but out of necessity. He walked slowly across the gangplank and did his duty. The hound has an iron bladder, Giordino thought, to have lasted this long. Then Romberg abruptly became alert, barked at a rabbit that darted through the grass and chased after him. "No Academy Award nomination for you, Romberg!" Giordino yelled at the dog as it took off onto a path leading along the bank. Then he flopped in a lawn chair, removed his sneakers and socks and propped his bare feet up on a railing, a bottle of Dixie beer clutched in one hand.

Onstage for the opening act, Pitt with his old .45 Colt stashed in a bucket at his feet and covered by a rag, Giordino with the Aserma 12-gauge shotgun from Pitt's hangar resting beneath the pad on his lawn chair, they watched the black dot that was the hovercraft grow in size as it flew over the marshlands, swirling and flattening a swath through the reeds. It was an amphibious craft that could make the transition from water to land. Propelled by twin aircraft engines with propellers at the stern, the hovercraft was supported by a cushion of air contained within a heavy rubber structure and produced by a smaller engine attached to a horizontal fan. Control was accomplished with a set of rudders much like those used on aircraft. Pitt and Giordino hatched as it moved effortlessly and rapidly over the marshlands and mud flats.

"She's fast," commented Pitt. "Capable of fifty miles an hour. About twenty feet long with a small cabin. By the look of her, she can carry six people."

"And none of them are smiling," muttered Giordino as the hovercraft approached the shantyboat and slowed. At that moment, Romberg came bounding from the swamp grass, barking up a storm.
