Lois smiled slightly as if enjoying a private joke. Her desire to spend time in the close confines of the bathysphere with the handsome Zavala had nothing to do with science. Well, maybe biology.

The camera went back to Kane.

“Great job, Joe,” Kane said. “At this time, I’d like to say a hello and offer personal thanks to everyone who has helped make this project possible. National Geographic, the New York Zoological Society, the government of Bermuda . . . and NUMA, of course.” He put his face closer to the camera, a move that made him look like a grinning grouper. “I’d also like to give my best to all the denizens at Davy Jones’s Locker.”

The room echoed with loud whoops and applause.

Logan was a soft-spoken Midwesterner and was normally reserved, but he slapped his thigh in his excitement. “Wow!” he exclaimed. “Nice of Doc to recognize us denizens still slaving away down here in the Locker. Too bad we can’t return the favor.”

Lois said, “Technically, it’s possible but not advisable. As far as the rest of the world is concerned, this undersea lab doesn’t even exist! We’re probably just a line item in a congressional budget cleverly disguised as an order of five-hundred-dollar toilet seats for the Navy.”

A smile came to Logan’s face. “Yes, I know, but it’s still too bad we can’t offer Doc our congratulations. I can’t think of anyone who deserves it more, after all he’s done.” He sensed from the blank expression on Lois’s face that he had made a verbal gaffe, and said, “You deserve a great deal of credit, Lois. After all, your work bringing the medusa project to its near conclusion allowed Max to get away for the bathysphere dive.”

“Thanks, Frank. We all gave up our normal lives to be here.”

A soft gong echoed throughout the room, and a green light blinked over a television monitor that showed what looked like a diamond diadem against dark velvet.

“Speaking of administrative duties,” Logan said with a wry grin, “your company is about to arrive.”

Lois wrinkled her nose. “Damn. I wanted to watch the rest of Doc’s dive.”

“Bring your guest back here to watch the show,” Logan suggested.

“Oh, no! I’m getting rid of him as quickly as I can,” Lois said, rising from her chair.

Lois Mitchell was nearly six feet tall, and in her late forties she had packed a few more pounds on her frame than she would have preferred. The voluptuous figure under the baggy sweat suit didn’t live up to contemporary ideals of beauty, but artists of a bygone day would have drooled over her curves and creamy skin, and the way her thick raven hair fell to her shoulders.

She bustled from the room and descended a spiral staircase to a brightly lit passageway. The tubelike corridor connected to a small chamber occupied by two men who stood at an instrument panel facing a heavy-duty double door.

One man said, “Hi, Lois. Touchdown is in forty-five seconds.” He pointed to a television screen set into the instrument panel.

The cluster of sparkling lights displayed on the control-room monitor had materialized into a submersible vehicle slowly descending through the murk. It resembled a large utility helicopter that had been stripped of its main rotor and was powered by variable-thrust turbines on the fuselage. Two figures were silhouetted in the bubble cockpit.

The room reverberated with the hum of motors. A diagram of the lab on the control panel began to blink, indicating that the airlock doors were open. After a few moments, the display stopped blinking, signifying that the doors had closed. The floor vibrated with the thrash of powerful pumps. When the water had been expelled from the airlock, the pumps went silent, and a green light flashed over the doors. At the push of a button on the control panel, the doors opened, and a briny smell rushed out. The submersible rested in a circular domed chamber. Curtains of seawater rolled off the fuselage and swirled down gurgling drains.

A hatch slid open in the side of the submersible, and the pilot got out. The men at the control panel went to help unload cartons of supplies from a cargo space behind the cockpit.

Lois strode over and greeted the man emerging from the passenger’s side. He was a couple of inches taller than she was and wore blue jeans, sneakers, and a windbreaker and baseball cap both emblazoned with the logo of the company that provided security for the lab.

She extended her hand. “Welcome to Davy Jones’s Locker. I’m Dr. Lois Mitchell, assistant director of the lab while Dr. Kane is away.”

“Pleased to meet you, ma’am,” the man said in a deep-voiced Southern drawl. “My name is Phelps.”

Lois had expected to see a quasi-military type like the tough-looking guards she had glimpsed on trips to the surface ship, where lab staff could take a break from the seafloor, but Phelps looked as if he had been assembled from spare parts. His arms were too long for his body, his hands too big for his arms, his head too big for his shoulders. With his sad-looking dark eyes and large mouth accented by drooping mustache, he had a hound-dog quality about him. He wore his dark brown hair in unfashionably long sideburns.

“Did you have a pleasant shuttle ride, Mr. Phelps?”

“Couldn’t have been better, ma’am. The best part was seeing the lights on the ocean bottom. Kept thinking this must be Atlantis.”

Lois cringed inwardly at the overblown comparison to the lost city.

“Glad to hear that,” she said. “Come to my office and we’ll chat about how we can help you.”

She led the way from the airlock along another tubular passageway, then up a spiral staircase to a low-lit, circular room. Fish nosed against the room’s transparent domed ceiling, creating the illusion that the sea was pressing in.

Phelps swiveled his head in wonder. “Talk about a water view! This is unbelievable, ma’am.”

“People find it hypnotic at first, but you get used to it. This is actually Dr. Kane’s office. I’m using it while he’s away. Have a seat. And please stop calling me ma’am. It makes me feel a hundred years old. I prefer Dr. Mitchell.”

“You sure look pretty good for a hundred years old, ma’am . . . I mean, Dr. Mitchell.”

Lois cringed again, and turned up the lights in the room so that the marine life was less visible and distracting. She opened a small office refrigerator, extracted two cold bottles of spring-water, and gave one to Phelps. She settled herself behind a plastic-and-chrome desk of starkly simple design.

Phelps pulled up a chair. “I’d like to thank you for your valuable time, Dr. Mitchell. You must have lots better things to do besides talking to a boring old security guy.”

If you only knew, Lois thought. She gave her visitor a polite smile. “How can I help you, Mr. Phelps?”

“My company sent me to probe for weaknesses in the sea-lab security.”

Lois wondered what kind of an idiot had sent Phelps to waste her time. She leaned back in her chair and pointed toward the transparent ceiling.

“We’ve got three hundred feet of ocean separating us from the surface, and it’s better than any castle moat. There’s a patrol ship up there with heavily armed guards from your company, backed up, if necessary, by the on-call resources of the U.S. Navy. How could we be any more secure than that?”

Phelps furrowed his brow. “With all due respect, Dr. Mitchell, the first thing you learn in this business is that there is no security system in the world that can’t be breached.”

Lois ignored the condescending tone. “Very well, then, let’s start with a virtual tour of the facility,” she said.

She swiveled her chair and tapped a computer keyboard. A three-dimensional diagram that looked like a series of globes and connecting tubes appeared on the monitor.

“The lab consists of four large spheres, arranged in a diamond shape and connected by tubular corridors,” Lois began. “We’re at the top of the administrative pod . . . here. Below us is the crew’s quarters and mess hall.” She manipulated the cursor to highlight another globe. “There’s a control room and some labs and storage in this pod. This pod contains the small nuclear plant. Air is supplied through a water-to-oxygen setup, with backup tanks for emergencies. We’re a few hundred yards from the edge of a deepwater canyon.”
