“Looks too big to be a communications line,” Summer said, studying the monitor.
“Hard to figure what would be out here,” Trevor remarked. “Outside of a few primitive hunting-and-fishing cabins, Gil Island is uninhabited.”
“Has to lead somewhere,” Dirk said. “As long as it’s not buried, we’ll be able to find out where.”
They continued sweeping through the grid, but rather than solve the underwater mystery they only added to it. A second line soon appeared, and then a third, all aligned in a converging angle to the north. Working their way through several more search lanes, they reached the conjunction. Like a giant seven-fingered hand lying on the bottom, the sonar revealed four additional lines that joined the others in a mass convergence. Piecing the images together, they could see that the lines all fanned out for approximately fifty yards, then ended abruptly. A single, heavier line extended north from the conjunction, running parallel to the shoreline. The sonar was able to track it for a short distance before it suddenly disappeared into the sediment close to shore. When they reached the end of the search grid, Dirk stopped the motor, then pulled in the sonar fish with Trevor’s assistance.
“It’s nearly seven,” Summer said. “We need to head back within the hour if we want to avoid running up the channel in the dark.”
“Plenty of time for a quick dive,” Dirk replied. “Might be our only chance.”
There was no argument from the others. Dirk slipped into a dry suit as Summer repositioned the boat over a marked spot where the seven lines had converged.
“Depth is ninety-five feet,” she said. “Be aware there is a large vessel on the radar headed our way, about fifteen miles to the north.” She turned to Trevor and asked, “I thought you said there’s no midweek cruise line traffic through here?”
Trevor gave her a confused look. “That has been my experience. They follow the schedules pretty tight. Must be a wayward freighter.”
Dirk poked his head in and eyed the radar screen. “I’ll have time for a good look before she gets too close.”
Summer turned the boat into the current while Trevor tossed an anchor off the bow and secured their position. Dirk adjusted his tank and weight belt, then stepped over the side.
He hit the water at nearly slack tide and was relieved to find the current minimal. Swimming toward the boat’s bow, he wrapped his fingers around the anchor line, then kicked to the bottom.
The cold green water gradually swallowed the surface light, forcing him to flick on a small headlamp strapped over his hood. A brown stony bottom dotted with urchins and starfish materialized out of the gloom, and he confirmed the depth at ninety-three feet as he adjusted his buoyancy. He let go of the anchor line and swam a wide circle around it until he found the object observed by the sonar.
It was a dark metal pipe that stretched across the seafloor, running beyond his field of vision. The pipe was about six inches in diameter, and Dirk could tell it had been placed on the bottom recently, as there was no growth or encrustation evident on its smooth surface. He kicked back to the anchor and dragged it over the pipe, resetting it in some adjacent rocks. He then followed the pipe down a gradual slope into deeper water until he found its open end twenty yards later. A small crater had been blasted into the seafloor around the opening, and Dirk noted a complete absence of marine life in the surrounding area.
He followed the pipe in the other direction, swimming into shallower water, until meeting the conjunction. It was actually three joints welded in tandem that fed six lines fanning to either side, plus one line out the end. A thicker, ten-inch pipe fed into the conjunction, trailing back toward Gil Island. Dirk followed the main pipe for several hundred feet until a ninety-degree joint sent it running north at a depth of thirty feet. Tracking it farther, he found it partially buried in a slit trench that had obscured its view from the sonar. He followed the pipe for several more minutes before deciding to give up the chase and turn back, his air supply starting to dwindle. He’d just reversed course when he suddenly detected a rumble under the surface. It was a deep sound, but in the water he could not tell which direction it came from. Following along the pipe, he noticed that sand started to fall away from its sides. He placed a gloved hand on the pipe and felt a strong vibration rattling down its length. With a sudden apprehension, he began kicking urgently toward the junction.
On the deck of the boat, Summer looked at her watch, noting that Dirk had been underwater nearly thirty minutes. She turned to Trevor, who sat on the rail watching her with an admiring gaze.
“I wish we could stay here longer,” she said, reading his mind.
“Me, too. I’ve been thinking. I’ll have to travel to Vancouver to file my report on the boat and see about getting a replacement. It might take me a few days, longer if I can milk it,” he added with a grin. “Any chance I can come see you in Seattle?”
“I’ll be angry if you don’t,” she replied with a smile. “It’s only a three-hour train ride away.”
Trevor started to reply when he noticed something in the water over Summer’s shoulder. It was a rising surge of bubbles about twenty yards from the boat. He stood to take a better look when Summer pointed to another mass of bubbles a short distance off the bow. In unison, they scanned the surrounding water, spotting a half dozen eruptions at various spots around the boat.
The rising bubbles expanded into a boiling tempest that began emitting white puffs of vapor. The vapor built rapidly, as billowing clouds of white mist emerged from the depths and expanded across the surface. Within seconds, the growing clouds had formed a circular wall around the boat, trapping Summer and Trevor in its center. As the vapor drew closer, Trevor said with alarm:
“It’s the Devil’s Breath.”

Thrusting his legs in a powerful scissors kick, Dirk skimmed rapidly along the main pipe. Though the visibility was too poor to see it, he could sense a nearby turbulence in the water and knew there something dangerous about the pipe’s emissions. The image of the Ventura and its dead crew flashed though his mind. Thinking of Summer and Trevor on the surface, he kicked his fins harder, ignoring the growing protest from his lungs.
He reached the pipe junction and immediately veered to his left, following the smaller pipe where he had first dropped down. He could now hear the turbulent rush of bubbles in the water from the high-pressure discharge. Chasing down the pipe, he finally caught sight of the anchor line ahead of him. He immediately shot toward the surface, angling toward the anchor line until joining it just below the boat’s bow.
When his head broke the surface, he felt like he was in a London fog. A thick white mist billowed low over the water. Keeping his face down, he swam along the hull to the stern, then stepped up a dive ladder Summer had dropped over the rail. He rose up on the lower rung just enough to peer over the transom. The white clouds of vapor floated across the deck, nearly obscuring the pilothouse just a few feet away.
Dirk pulled his regulator out of his mouth long enough to yell for Summer. An acrid taste immediately filled his mouth and he shoved the regulator back in and took a breath from his air tank. He stood and listened for several seconds, then stepped off the ladder and dropped into the water, his heart skipping a beat.
There had been no reply, he realized, because the boat was empty.
Two hundred yards to the west and ten feet under the water, Trevor thought he was going to die. He couldn’t believe how quickly the frigid water had sapped his strength and energy, and nearly his will to live. If not for the radiant pearl gray eyes of Summer visibly imploring him on, he might have given up altogether.
