"Jenny, I'm a recreational diver, no decompression needed because I work within the limits exactly as Bob Carney taught me, and I never dive without my Marathon diving computer, you know that."

"I also know that whenever you dive there's always a chance of some kind of decompression sickness."

"True, but very small." He squeezed her hand. "Now stop worrying and go to bed."

She kissed him on the top of his head and went out. He returned to his book, carrying it across to the couch by the window, stretching out comfortably. He didn't seem to need so much sleep these days, one of the penalties of growing old, he imagined, but after a while his eyes started to close and sleep he did, the book sliding to the floor.

He came awake with a start, light beaming in through the venetian blinds. He lay there for a moment, then checked his watch. It was a little after five and he got up and went out on to the veranda. It was already dawn, light breaking on the horizon, but strangely still, and the sea was extraordinarily calm, something to do with the hurricane having pa.s.sed. Perfect for diving, absolutely perfect.

He felt cheerful and excited at the same time, hurried into the kitchen, put the kettle on and made a stack of cheese sandwiches while it boiled. He filled a thermos with coffee, put it in a holdall with the sandwiches and took his old reefer coat down from behind the door.

He left the jeep for Jenny and walked down to the harbor. It was still very quiet, not too many people about, a dog barking in the distance. He dropped into his inflatable dinghy at the dock, cast off and started the outboard motor, threaded his way out through numerous boats until he came to his own, the Rhoda Rhoda, named after his wife, a thirty-five-foot Sport Fisherman with a flying bridge.

He scrambled aboard, tying the inflatable on a long line, and checked the deck. He had four air tanks standing upright in their holders; he'd put them in the day before himself. He opened the lid of the deck locker and checked his equipment. There was a rubber and nylon diving suit which he seldom used, preferring the lighter, three-quarter-length one in orange and blue. Fins, mask, plus a spare because the lenses were correctional according to his eye prescription, two buoyancy jackets, gloves, air regulators and his Marathon computer.

"Carney training," he said softly, "never leave anything to chance."

He went round to the prow and unhitched from the buoy, then went up the ladder to the flying bridge and started the engines. They roared into life and he took the Rhoda Rhoda out of harbor toward the open sea with conscious pleasure. out of harbor toward the open sea with conscious pleasure.

There were all his favorite dives to choose from, the Cow & Calf, Carval Rock, Congo, or there was Eagle Shoal if he wanted a longer trip. He'd confronted a lemon shark there only the previous week, but the sea was so calm he just headed straight out. There was always Frenchman's Cap to the south and west and maybe eight or nine miles, a great dive, but he just kept going, heading due south, pushing the Rhoda Rhoda up to fifteen knots, pouring himself some coffee and breaking out the sandwiches. The sun was up now, the sea the most perfect blue, the peaks of the islands all around, a breathtakingly beautiful sight. Nothing could be better. up to fifteen knots, pouring himself some coffee and breaking out the sandwiches. The sun was up now, the sea the most perfect blue, the peaks of the islands all around, a breathtakingly beautiful sight. Nothing could be better.

"My G.o.d," he said softly, "it's a d.a.m.n privilege to be here. What in h.e.l.l was I doing with my life all those years?"

He lapsed into a kind of reverie, brooding about things, and it was a good thirty minutes later that he suddenly snapped out of it and checked on his position.

"Christ," he said, "I must be twelve miles out."

Which was close to the edge of things and that awesome place where everything simply dropped away and it was two thousand feet to the bottom, except for Thunder Point and that, he knew, was somewhere close. But no one ever dived there, the most dangerous reef in the entire region. Even Carney didn't dive there. Strong currents, a nightmare world of fissures and channels. Carney had told him that years before an old diver had described it to him. A hundred and eighty feet on one side, then the ridge of the reef at around seventy, and two thousand feet on the other. The old boy had hit bad trouble, had only just made it to the surface, had never tried again. Few people even knew where it was anyway, and the sea out there was generally so turbulent that that in itself was enough to keep anyone away, but not today. It was a millpond. Baker had never seen anything like it. A sudden excitement surged in him and he switched on his fathometer, seeking the bottom, throttling back the engines, and then he saw it, the yellow ridged lines on the black screen.

He killed the engine and drifted, checking the depth reading until he was certain he was above the ridge of the reef at seventy feet, then scrambled round to the prow and dropped the anchor. After a while, he felt it bite satisfactorily and worked his way round to the deck. He felt incredibly cheerful as he stripped, pulled on the orange and blue nylon diving suit, then quickly a.s.sembled his gear, clamping a tank to his inflatable. He strapped the computer to the line of his air pressure gauge, then eased himself into the jacket, taking the weight of the tank, strapping the Velcro wrappers firmly across his waist and hooking a net diving bag to his weight belt as he always did with a spotlight inside in case he came across anything interesting. He pulled on a pair of diving gloves, then sat with his feet on the platform at the stern and pulled on his fins. He spat on his mask, rinsed it, adjusted it to his face, then simply stood up and stepped into the water.

It was incredibly clear and blue. He swam round to the anchor rope, paused, then started down, following the line. The sensation of floating in s.p.a.ce was, as always, amazing, a silent, private world, sunlight at first, but fading as he descended.

The reef where the anchor was hooked was a forest of coral and sea gra.s.s, fish of every conceivable description, and suddenly a barracuda that was at least five feet long swerved across his vision and paused, turning toward him threateningly, which didn't bother Baker in the slightest, because barracuda were seldom a threat to anyone.

He checked his dive computer. It not only indicated the depth he was at, but told him how long he was safe there and constantly altered its reading according to any change in depth he made during the dive. He was at this point at seventy feet and he turned and headed over to the left-hand side, where the reef slid down to a hundred and eighty. He went over the edge, then changed his mind and went up again. It was amazing how much an extra ten or fifteen feet reduced your bottom time.

There was a reasonably strong current; he could feel it pushing him to one side. He imagined what it must be like when conditions were bad, but he was d.a.m.ned if that was going to stop him having a look at the big drop. The edge of the reef over there was very clearly defined. He paused, holding on to a coral head and peered over, looking down the cliff face into a great blue vault that stretched into infinity. He went over, descended to eighty feet and started to work his way along.

It was interesting. He noted a considerable amount of coral damage, large sections having obviously been torn away, recently, presumably the result of the hurricane although they were on a fault line here and earth tremors were also common. Some distance ahead, there was a very obvious section where what looked like an entire overhang had gone revealing a wide ledge below, and there was something there, perched on the ledge yet part of it hanging over. Baker paused for a moment, then approached cautiously.

It was then that he received not only the greatest thrill of his diving career but the greatest shock of a long life. The object which was pressed on the ledge and partly sticking out over two thousand feet of water was a submarine.

During his naval service Baker had done a training course in a submarine when based in the Philippines. No big deal, just part of general training, but he remembered the lectures, the training films they'd had to watch, mainly Second World War stuff, and he recognized what he was looking at instantly. It was a type VII U-boat, by far the most common craft of its kind used by the German Kriegsmarine, the configuration was unmistakable. The conning tower was encrusted with marine growth, but when he approached he could still discern the number on the side - 180. The attack and control room periscopes were still intact and there was a snorkel. He recalled having heard that the Germans had gradually introduced that as the war progressed, a device that enabled the boat to proceed under water much faster because it was able to use the power of its diesel engines. Approximately two-thirds of it rested stern first on the ledge and the prow jutted out into s.p.a.ce.

He glanced up aware of a school of horse-eyed jacks overhead mixed with silversides, then descended to the top of the conning tower and hung on to the bridge rail. Aft was the high gun platform with its 20mm cannon and forward and below him was the deck gun, encrusted, as was most of the surface, with sponge and coral of many colors.

The boat had become a habitat as with all wrecks, fish everywhere, yellow-tail snappers, angel and parrot fish and sergeant-majors and many others. He checked his computer. On the bridge he was at a depth of seventy-five feet and he had only twenty minutes at the most before the need to surface.

He drifted away a little distance to look the U-boat over. Obviously the overhang, which had recently been dislodged, had provided a kind of canopy for the wreck for years, protecting it from view, and at a site which was seldom visited, it had been enough. That U-boats had worked the area during the Second World War was common knowledge. He'd known one old sailor who'd always insisted that crews would come ash.o.r.e on St. John by night in search of fresh fruit and water, although Baker had always found that one hard to swallow.

He swung over to the starboard side and saw what the trouble had been instantly, a large, ragged gash about fifteen feet long in the hull below the conning tower. The poor b.a.s.t.a.r.ds must have gone down like a stone. He descended, holding on to a jagged, coral-encrusted edge, and peered into the control room. It was dark and gloomy in there, silverfish in clouds, and he got the spotlight from his dive bag and shone it inside. The periscope shafts were clearly visible, again encrusted like everything else, but the rest was a confusion of twisted metal, wires and pipes. He checked his computer, saw that he had fifteen minutes, hesitated, then went inside.

Both the aft and forward water-tight doors were closed, but that was standard practice when things got bad. He tried the unlocking wheel on the forward hatch, but it was immovable and hopelessly corroded. There were some oxygen bottles, even a belt of some kind of ammunition, and the most pathetic thing of all, a few human bones in the sediment of the floor. Amazing that there was any trace at all after so many years.

Suddenly he felt cold. It was as if he was an intruder who shouldn't be here. He turned to go and his light picked out a handle in the corner, very like a suitcase handle. He reached for it, the sediment stirred and he found himself clutching a small briefcase in some kind of metal, encrusted like everything else. It was enough and he went out through the gash in the hull, drifted up over the edge of the reef and went for the anchor.

He made it with five minutes to spare. Stupid b.a.s.t.a.r.d, he told himself, taking such a chance, and he ascended just by the book, one foot per second, one hand sliding up the line, the briefcase in the other, leaving the line at twenty feet to swim under the boat and surface at the stern.

He pushed the briefcase on board, then wriggled out of his equipment, which was always the worst part. You're getting old, Henry, he told himself as he scrambled up the ladder and turned to heave his buoyancy jacket and tank on board.

He schooled himself to do everything as normal, stowing away the tank and the equipment following his usual routine. He toweled himself dry, changed into jeans and a fresh denim shirt, all the time ignoring the briefcase. He opened his thermos and poured some coffee, then went and sat in one of the swivel chairs in the stern, drinking and staring at the briefcase encrusted with coral.

The encrusting was superficial more than anything else. He got a wire brush from his tool kit and applied it vigorously and realized at once that the case was made of aluminium. As the surface cleared, the Eagle and Swastika of the German Kriegsmarine was revealed etched into the top right-hand corner. It was secured by two clips and there was a lock. The clips came up easily enough, but the lid remained obstinately down, obviously locked, which left him little choice. He found a large screwdriver, forced it in just above the lock and was able to prize open the lid within a few moments. The inside was totally dry, the contents a few photos and several letters bound together by a rubber band. There was also a large diary in red Moroccan leather stamped with a Kriegsmarine insignia in gold.

The photos were of a young woman and two little girls. There was a date on the back of one of them at the start of a handwritten paragraph in German, August 8, 1944. The rest made no sense to him as he didn't speak the language. There was also a faded snap of a man in Kriegsmarine uniform. He looked about thirty and wore a number of medals, including the Knight's Cross at his throat. Someone special, a real ace from the look of him.

The diary was also in German. The first entry was April 30, 1945, and he recognized the name, Bergen, knew that was a port in Norway. On the flyleaf was an entry he did understand. Korvettenkapitan Paul Friemel, U180, obviously the captain and owner of this diary.

Baker flicked through the pages, totally frustrated at being unable to decipher any of it. There were some twenty-seven entries, sometimes a page for each day, sometimes more. On some occasions there was a notation to indicate position, and he had little difficulty in seeing from those entries that the voyage had taken the submarine into the Atlantic and south to the Caribbean.

The strange thing was the fact that the final entry was dated May 28, 1945, and that didn't make too much sense. Henry Baker had been sixteen years of age when the war in Europe had ended, and he recalled the events of those days with surprising clarity. The Russians had reached Berlin and reduced it to h.e.l.l on earth, and Adolf Hitler, holed up in the Fuhrer Bunker at the Reich Chancellery, had committed suicide on May the 1st at 10:30 P.M. along with his wife of a few hours only, Eva Braun. That was the effective end of the Third Reich and capitulation had soon followed. If that were so, what in the h.e.l.l was U180 doing in the Virgin Islands with a final log entry dated May 28?

If only he could speak German, and the further frustrating thing was that he didn't know a soul in St. John who did. On the other hand, if he did, would he want to share such a secret? One thing was certain: If news of the submarine and its whereabouts got out, the place would be invaded within days.

He flicked through the pages again, paused suddenly and turned back a page. A name jumped out at him. Reichsleiter Martin Bormann Reichsleiter Martin Bormann. Baker's excitement was intense. Martin Bormann, Head of the n.a.z.i Party Chancellery and Secretary to the Fuhrer. Had he escaped from the Bunker at the end, or had he died trying to escape from Berlin? How many books had been written about that?

He turned the page idly and another name came out at him: the Duke of Windsor Duke of Windsor. Baker sat staring at the page, his throat dry, and then he very carefully closed the diary and put it back in the case with the letter and photos. He closed the lid, put the case in the wheelhouse and started the engines. Then he went and hauled in the anchor.

Whatever it was, it was heavy, had to be. He had a U-boat that had gone down in the Virgin Islands three weeks after the end of the war in Europe, a private diary kept by the captain which mentioned the most powerful man in n.a.z.i Germany after Hitler, and the Duke of Windsor.

"My G.o.d, what have I got into?" he murmured.

He could go to the authorities, of course, the Coast Guard, for example, but it had been his find, that was the trouble, and he was reluctant to relinquish that. But what in the h.e.l.l to do next, and then it came to him and he laughed out loud.

"Garth Travers, of course," and he pushed up to full throttle and hurried back to St. John.

In 1951 as a Lieutenant in the U.S. Navy, Baker had been a.s.signed as liaison officer to the British Royal Navy destroyer Persephone Persephone, which was when he had first met Garth Travers, a gunnery officer. Travers was on the fast track, had taken a degree in history at Oxford University, and the two young officers had made a firm friendship, cemented by five hours in the water one dark night off the Korean coast, which they'd spent hanging on to each other after a landing craft on which they'd been making a night drop with Royal Marine Commandos had hit a mine.

And Travers had gone on to great things, had retired a Rear Admiral. Since then he'd written several books on naval aspects of the Second World War, had translated a standard work on the Kriegsmarine from the German which Baker's publishing house had published in the last year he'd been in the business. Travers was the man, no doubt about it.

He was close insh.o.r.e to St. John now and saw another Sport Fisherman bearing down on him and he recognized the Sea Raider Sea Raider, Bob Carney's boat. It slowed, turning toward him, and Baker slowed too. There were four people in the stern dressed for diving, three women and a man. Bob Carney was on the flying bridge.

"Morning, Henry," he called. "Out early. Where you been?"

"French Cap." Baker didn't like lying to a friend but had no choice.

"Conditions good?"

"Excellent, millpond out there."

"Fine." Carney smiled and waved. "Take care, Henry."

The Sea Raider Sea Raider moved away and Baker pushed up to full power and headed for Cruz Bay. moved away and Baker pushed up to full power and headed for Cruz Bay.

When he reached the house, he knew at once that Jenny wasn't there because the jeep had gone. He checked his watch. Ten o'clock. Something must have come up to take her out. He went into the kitchen, got a beer from the icebox and went to his study, carrying the briefcase in one hand. He placed it on the desk, pulled his phone file across and leafed through it one-handed while he drank the beer. He found what he was looking for soon enough and checked his watch again. Ten after ten, which meant ten after three in the afternoon in London. He picked up the telephone and dialed.

In London it was raining, drumming against the windows of the house in Lord North Street where Rear Admiral Garth Travers sat in a chair by the fire in his book-lined study enjoying a cup of tea and reading the Times Times. When the phone rang, he made a face, but got up and went to the desk.

"Who am I talking to?"

"Garth? It's Henry - Henry Baker."

Travers sat down behind the desk. "Good G.o.d, Henry, you old sod. Are you in London?"

"No, I'm calling from St. John."

"Sounds as if you're in the next room."

"Garth, I've got a problem, I thought you might be able to help. I've found a U-boat."

"You've what?"

"An honest-to-G.o.d U-boat, out here in the Virgins, on a reef about eighty feet down. One-eighty was the number on the conning tower. It's a type seven."

Travers' own excitement was extreme. "I'm not going to ask you if you've been drinking. But why on earth has no one discovered it before?"

"Garth, there are hundreds of wrecks in these waters; we don't know the half of it. This is in a bad place, very dangerous. No one goes there. It's half on a ledge which was protected by an overhang, or I miss my guess. There's a lot of fresh damage to the cliff face. We've just had a hurricane."

"So what condition is she in?"

"There was a gash in the hull and I managed to get in the control room. I found a briefcase in there, a watertight job in aluminium."

"With a Kriegsmarine insignia engraved in the top right-hand corner?"

"That's right!"

"Standard issue, fireproof and waterproof, all that sort of thing. What did you say the number was, one-eighty? Hang on a minute and I'll look it up. I've got a book on one of my shelves that lists every U-boat commissioned by the Kriegsmarine during the War and what happened to them."

"Okay."

Baker waited patiently until Travers returned. "We've got a problem, old son, you're certain this was a type seven?"

"Absolutely."

"Well the problem is that one-eighty was a type nine, dispatched to j.a.pan from France in August forty-four with technical supplies. She went down in the Bay of Biscay."

"Is that so?" Baker said. "Well how does this grab you? I found the personal diary of a Korvettenkapitan Paul Friemel in that briefcase and the final entry is dated May twenty-eighth, nineteen forty-five."

"But V.E. day in Europe was May the eighth," Travers said.

"Exactly, so what have we got here? A German submarine with a false number that goes down in the Virgins three weeks after the end of the b.l.o.o.d.y war."

"It certainly is intriguing," Travers said.

"You haven't heard the best bit, old buddy. Remember all those stories about Martin Bormann having escaped from Berlin?"

"Of course I do."

"Well I can't read German, but I sure can read his name and it's right here in the diary, and another little bombsh.e.l.l for you. So is the Duke of Windsor's."

Travers loosened his tie and took a deep breath. "Henry, old son, I must see that diary."

"Yes, that's what I thought," Baker said. "There's the British Airways overnight flight leaving Antigua around eight this evening our time. I should be able to make it. Last time I used it we got into London Gatwick at nine o'clock in the morning. Maybe you could give me a late breakfast."

"I'll be looking forward to that," Travers said and replaced the receiver.

The Professional a.s.sociation of Diving Instructors, of which Henry was a certificated member, has strict regulations about flying after diving. He checked his book of rules and discovered that he should wait at least four hours after a single no-decompression dive at eighty feet. That gave him plenty of leeway, especially if he didn't fly down to Antigua until the afternoon, which was exactly what he intended.

First he rang British Airways in San Juan. Yes, they had s.p.a.ce in the first-cla.s.s cabin on BA flight 252 leaving Antigua at 20.10 hours. He made the booking and gave them one of his Gold Card numbers. Next he rang Carib Aviation in Antigua, an air-taxi firm he'd used before. Yes, they were happy to accept the charter. They'd send up one of their Partenavias early afternoon to St. Thomas. If they left for the return trip to Antigua at four-thirty, they'd be there by six at the latest.

He sat back, thinking about it. He'd book a water taxi across to Charlotte Amalie, the main town on St. Thomas. Forty minutes, that's all it would take, fifteen at the most by taxi to the airport. Plenty of time to pack and get himself ready, but first he had to see Jenny.

The waterfront was bustling when he walked down into Cruz Bay this time. It was a picturesque little town, totally charming and ever so slightly run-down in the way of most Caribbean ports. Baker had fallen in love with the place the first time he'd seen it. It was everything you'd hope for. He used to joke that all it needed was Humphrey Bogart in a sailor's cap and denims running a boat from the harbor on mysterious missions.

Jenny's Place was slightly back from the road just before Mongoose Junction. There were steps up to the veranda, a neon sign above the door. Inside it was cool and shaded, two large fans revolving in the low ceiling. There were several booths against the walls, a scattering of marble-topped tables across a floor of black and white tiles. There were high stools at the long mahogany bar, bottles on gla.s.s shelves against the mirrored wall behind. A large, handsome black man with graying hair was polishing gla.s.ses, Billy Jones, the barman. He had the scar tissue around the eyes and the slightly flattened nose of a professional fighter. His wife, Mary, was manager.

He grinned. "Hi there, Mr. Henry, you looking for Jenny?"

"That's right."

"Went down the front with Mary to choose the fish for tonight. They shouldn't be too long. Can I get you something?"

"Just a coffee, Billy, I'll have it outside."

He sat in a cane chair on the veranda, drinking the coffee and thinking about things, was so much within himself that he didn't notice the two women approach until the last minute.

"You're back, Henry."

He looked up and found Jenny and Mary Jones coming up the steps. Mary wished him good morning and went inside and Jenny sat on the rail, her figure very slim in tee-shirt and blue jeans.

She frowned. "Is something wrong?"

"I've got to go to London," he told her.

"To London? When?"

"This afternoon."
