“Sounds vaguely familiar.”

“One of the most stubborn mysteries of the northern seas. The Pilottown tramped back and forth between Tokyo and the West Coast until ten years ago, when her crew reported her sinking in a storm. A search was launched and no trace of the ship was found. Two years later an Eskimo stumbled on the Pilottown caught in the ice about ninety miles above Nome. He went aboard but found the ship deserted, no sign of the crew or cargo. A month later, when he returned with his tribe to remove whatever they could find of value, it was gone again. Nearly two years passed, and she was reported drifting below the Bering Strait. The Coast Guard was sent out but couldn’t locate her. The Pilottown wasn’t sighted again for eight months. She was boarded by the crew of a fishing trawler. They found her in reasonably good shape. Then she disappeared for the last time.”

“I seem to recall reading something…” Pitt paused. “Ah, yes, the ‘Magic Ship.’ “

“That’s what the news media dubbed her,” Dover acknowledged. “They described her disappearing act as a ‘now you see it, now you don’t’ routine.”

“They’ll have a field day when it gets out she was drifting around for years with a cargo of nerve agent.”

“No way of predicting the horror if the hull had been crushed in an ice pack or shattered on a rocky shore, creating an instant spill,” Dover added.

“We’ve got to get in her cargo holds,” said Pitt. “Contact Mendoza, give her the position of the wreck and tell her to airlift a team of chemists to the site. We’ll approach from the water.”

Dover nodded. “I’ll see to the launch.”

“Throw in acetylene equipment in case we have to cut our way inside.”

Dover bent over the chart table and stared solemnly at the center of the marked circle. “I never thought for a minute I’d stand on the deck of the Magic Ship.”

“If you’re right,” said Pitt, staring into his coffee mug, “the Pilottown is about to give her last performance.”

The sea had been calm, but by the time the Catawba’s launch was a quarter-mile from the lonely, forbidding coast, a twenty-knot wind kicked up the water. The spray, tainted by the nerve agent, struck the cabin windows with the fury of driven sand. Yet where the derelict lay beached, the water looked reasonably peaceful, protected as it was by jagged pinnacles of rock that rose up a hundred yards offshore like solitary chimneys from burned-out houses.

Far above the turbulent waters Augustine Volcano seemed calm and serene in the late afternoon sun. It was one of the most beautifully sculptured mountains in the Pacific, rivaling the classic contour of Mount Fuji in Japan.

The powerful launch surfed for an instant on a whitecapped swell before diving over the crest. Pitt braced his feet, gripped a railing with both hands while his eyes studied the shore.

The wreck was heeled over at a twenty-degree angle and her stern section blanketed in brown rust. The rudder was canted in the full starboard position and two barnacle-encrusted blades of the propeller protruded from the black sand. The letters of her name and home port were too obscured to read.

Pitt, Giordino, Dover, the two EPA scientists and one of the Catawba’s junior officers all were garbed in white encapsulating suits to protect them from the plumes of deadly spray. They communicated by tiny transmitters inside their protective headgear. Attached to their waist belts were intricate filter systems designed to refine clean, breathable air.

The sea around them was carpeted with dead fish of every species. A pair of whales rolled lifelessly back and forth with the tide, united in rotting decay with porpoises, sea lions and spotted seals. Birds by the thousands floated amid the morbid debris. Nothing that had lived in the area had escaped.

Dover expertly threaded the launch between the threatening offshore barrier of projecting rock, the remnant of an ancient coastline. He slowed, waiting for a momentary lull in the surf, biding his time while carefully eyeing the depth. Then as a wave slammed onto the shore and its backwash spilled against the next one coming in, he aimed the bow at the small spit of sand formed around the base of the wreck and pushed the throttle forward. Like a horse bracing for the next hurdle at the Grand National, the launch rose up on the wave crest and rode it through the swirling foam until the keel dropped and scraped onto the spit.

“A neat bit of handiwork,” Pitt complimented him.

“All in the timing,” Dover said, a grin visible behind his helmet’s face mask. “Of course, it helps if you land at low tide.”

They tilted back their heads and stared up at the wreck towering above them. The faded name on the stern could be deciphered now. It read Pilottown.

“Almost a pity,” Dover said reverently, “to write finish to an enigma.”

“The sooner the better,” Pitt said, his tone grim as he considered the mass death inside.

Within five minutes the equipment was unloaded, the launch securely moored to the Pilottown’s rudder, and the men laboriously climbing the steep slope on the port side of the stern. Pitt took the lead, followed by Giordino and the rest as Dover brought up the rear.

The incline was not made up of solid rock but rather a combination of cinder ash and mud with the consistency of loose gravel. Their boots struggled to find a foothold, but mostly they slid back two steps for every three they gained. The dust from the ash rose and clung to their suits, coating them a dark gray. Soon the sweat was seeping through their pores and the increasingly heavy rasp of their breathing became more audible over the earphones inside their helmets.

Pitt called a halt at a narrow ledge, not four feet wide and just long enough to hold all six men. Wearily Giordino sank to a sitting position and readjusted the straps that held the acetylene tank to his back. When he could finally pant a coherent sentence, he said, “How in hell did this old rust bucket jam herself in here?”

“She probably drifted into what was a shelving inlet before 1987,” replied Pitt. “According to Mendoza, that was the year the volcano last erupted. The explosion gases must have melted the ice around the mantle, forming millions of gallons of water. The mudflow, along with the cloud of ash, poured down the mountain until it met the sea and buried the ship.”

“Funny the stern wasn’t spotted before now.”

“Not so remarkable,” Pitt answered. “So little is showing it was next to impossible to detect from the air, and beyond a mile from shore it blends into the rugged shoreline and becomes nearly invisible. Erosion caused by recent storms is the only reason she’s uncovered now.”

Dover stood up, pressing his weight against the steep embankment to maintain his balance. He unraveled a thin knotted nylon rope from his waist and unfolded a small grappling hook tied to the end.

He looked down at Pitt. “If you’ll support my legs, I think I can heave the hook over the ship’s railing.”

Pitt grasped his left leg as Giordino edged over and held the right. The burly Coast Guardsman leaned back over the lip of the ledge, swung the hook in a widening arc and let it fly.

It sailed over the stern rails and caught.

The rest of the ascent took only a few minutes. Pulling themselves upward, hand over hand, they soon climbed onto the deck. Heavy layers of rust mingled with ash flaked away beneath their feet. What little they could see of the Pilottown looked a dirty, ugly mess.

“No sign of Mendoza,” said Dover.

“Nearest flat ground to land a copter is a thousand yards away,” Pitt replied. “She and her team will have to hike in.”

Giordino walked over to the railing beside the corroded shaft of the jackstaff and stared at the water below. “The poison must be seeping through the hull during high tide.”
