Flood Tide

“Up with the birds, that's us,” Pitt said, nodding humorously. “How was your trip from Kenosha?”

“Calm water all the way,” answered Wilbanks.

Both men spoke in a soft Southern accent. Pitt liked them almost immediately. He didn't need a drawing to see they were a professional, job-dedicated pair. They watched amused as Julia jumped from the dock, landing on the deck with the finesse of a limber cat. She was dressed in jeans and a sweater under a nylon windbreaker.

“She's a fine, no-nonsense boat,” said Pitt, admiring the Divercity.

Wilbanks nodded in agreement. “She does the job.” He turned to Julia. “I hope you don't mind roughing it, ma'am. We're not equipped with a head.”

“Don't worry about me,” Julia said, smiling. “I've got an iron bladder.”

Pitt looked across the water of the little harbor at the seemingly endless lake. “Light breeze, one- to two-foot waves, conditions look good. Are we ready to cast off?”

Hall nodded and unwound the mooring lines from the dock's cleats. Just as he was about to climb on board, he pointed down the dock at a figure awkwardly approaching and waving wildly. “Is he with you?”

Pitt found himself staring at Al Giordino, who was stomping across the wooden planks on a pair of crutches, his wounded leg encased in a plaster cast from ankle to crotch. Giordino flashed his celebrated smile and said, “A pox on your house for thinking you could leave me onshore while you got all the glory.”

Happy to see his old friend, Pitt said, “You can't say I didn't try.”

Wilbanks and Hall gently lifted Giordino over the side and sat him on a long cushion that lay on a raised hump in the middle of the boat. Pitt introduced him to the crew as Julia fussed over him and pressed a cup of coffee in his hand from a thermos she carried in a picnic basket.

“Shouldn't you be in a hospital?” she asked.

“I hate hospitals,” Giordino grumbled. “Too many people die in them.”

“Is everyone aboard who's coming aboard?” Wilbanks inquired.

“All present and accounted for,” replied Pitt.

As soon as they cleared the harbor, Wilbanks pushed the throttle forward and the Divercity leaped ahead, bow clear of the water, until she was skimming the waves at nearly thirty miles an hour. While Julia and Giordino sat aft, enjoying the view and the begi

It seemed hardly any time had passed before Wilbanks slowed the boat and a

Pitt helped Hall drop over the magnetometer sensor and the side-scan sonar towfish, trailing them behind the stern of the boat on tethered cables. After tying off the cables, they returned to the cabin.

Wilbanks steered the boat toward the end of a line displayed on the monitor that led to a search grid with parallel lanes. “Four hundred meters to go.”

“I feel like I'm taking part in an adventure,” said Julia.

“You're going to be sadly disappointed,” Pitt laughed. “Ru

Pitt took over the magnetometer duties as Hall set up the Klein & Associates Systems 2000 sonar. He sat on a stool in front of the high-resolution color video display unit that was mounted in the same console as a thermal printer that recorded the floor of the lake in 256 shades of gray.

“Three hundred meters,” Wilbanks droned.

“What range are we set for?” Pitt asked Hall.

“Since we're hunting for a large target five hundred feet in length, we'll run thousand-meter lanes.” He pointed to the lake-bed detail that was begi

“Speed?”

“The water's pretty calm. I think we can run at ten miles an hour and still get a sharp recording.”

“Can I watch?” asked Julia from the cabin doorway.

“Be my guest,” said Hall, making room for her in the cramped quarters.

“The detail is amazing,” she said, staring at the image from the printer. “You can clearly see ripples in the sand.”

“The resolution is good,” Hall lectured her, “but nowhere near the definition of a photograph. The sonar image translates similar to a photo that's been duplicated and then run through a copy machine three or four times.”

Pitt and Hall exchanged grins. Observers always became addicted to watching the sonar data. Julia would be no different. They knew that she would gaze entranced for hours, enthusiastically waiting for the image of a ship to materialize.

“Starting lane one,” Wilbanks proclaimed.

“What's our depth, Ralph?” Pitt asked.

Wilbanks glanced up at his depth sounder, which hung from the roof on one side of the helm. “About four hundred ten feet.”

An old hand at search-and-survey, Giordino shouted from his comfortable position on the cushion where he lay with his cast propped up on a railing. “I'm going to take a siesta. Yell out if you spot anything.”

The hours passed slowly as the Divercity plowed through the low waves at ten miles an hour mowing the lawn, the magnetometer ticking away, the recording line trailing down the center of the graph paper until swinging off to the sides when it detected the presence of iron. In unison, the side-scan sonar emitted a soft clack as the thermal plastic film unreeled from the printer. It revealed a lake bed cold and desolate and free of human debris.

“It's a desert down there,” said Julia, rubbing tired eyes.

“No place to build your dream house,” said Hall with a little grin.

“That finishes lane twenty-two,” Wilbanks broadcast. “Coming around on lane twenty-three.”

Julia looked at her watch. “Lunchtime,” she a

“I'm always hungry,” Giordino called out from the back of the boat.

“Amazing.” Pitt shook his head incredulously. “At twelve feet away, outside in a breeze with the roar of the outboard motor, he can still hear the mere mention of food.”

“What delicacies have you prepared?” Giordino asked Julia, having dragged himself to the cabin doorway.

“Apples, granola bars, carrots and herbal ice tea. You have your choice between hummus and avocado sandwiches. It's what I call a healthy lunch.”

Every man on the boat looked at each of the others with utter horror. She couldn't have received a more unpalatable reaction if she had said she was volunteering their services as diaper changers at a day-care center. Out of deference to Julia none of the men said anything negative, since she went to the bother of fixing lunch. The fact that she was a woman and their mothers had raised them all as gentlemen added to the dilemma. Giordino, however, did not come from the old school. He complained vociferously.

“Hummus and avocado sandwiches,” he said disgustedly. “I'm going to throw myself off the boat and swim to the nearest Burger King—”

“I have a reading on the mag!” Pitt interrupted. “Anything on the sonar?”

“My sonar towfish is trailing farther astern than your mag sensor,” said Hall, “so my reading will lag behind yours.”
