"Okay. Sounds good. Let's do it."

"I can't drive you back to Oslo. I'm just not fit to do it."

"I don't want you to. I've got the painting now. The last thing I need is for you to land us upside-down in a ditch."

Hill picked up The Scream The Scream and wrapped it back up in the blue sheet. He followed Ulving outside and leaned over the pa.s.senger seat of Ulving's sporty Mercedes, trying to set the priceless painting in the back of the little two-seater. Wrestling the bulky square of cardboard over the front seat headrest, Hill heard a dismaying thump. "s.h.i.t! I've dented the f.u.c.ker on the G.o.dd.a.m.ned headrest." and wrapped it back up in the blue sheet.

He glared at Ulving. "Drive."

Ulving drove to the hotel, only a few minutes away. "We can get a day room."

"Fine. Do it."

Ulving and Hill walked into the hotel, leaving The Scream The Scream unattended in the car. Hill, who was breathtakingly careless whenever he was not overtly paranoid, hardly gave it a thought. Who steals cars in Norway? unattended in the car. Hill, who was breathtakingly careless whenever he was not overtly paranoid, hardly gave it a thought. Who steals cars in Norway?

Hill had yet to phone Butler. He spotted a pay phone near the front desk. The Scream's The Scream's bra.s.s nameplates jingled in his pocket as he strode across the lobby. bra.s.s nameplates jingled in his pocket as he strode across the lobby.

"I'm just going to phone Sid," Hill told Ulving, although it was John Butler and not Sid Walker that he planned to call. Hill couldn't have phoned Walker if he had wanted to, since he had neglected to write down his number.

Ulving tagged along. That wouldn't do. Hill turned to Ulving. f.u.c.k off! f.u.c.k off! That was English, not American. Hill changed idiom and spoke aloud. "I need to talk to Sid. Go screw yourself!" That was English, not American. Hill changed idiom and spoke aloud. "I need to talk to Sid. Go screw yourself!"

"Oh, excuse me," Ulving said, retreating.

"John, it's Chris."

"Charley, where the h.e.l.l are you?"

Butler was a good man in a crisis, but his voice was a near-whisper that betrayed his tension.

Hill whispered, too, to foil Ulving. "I've got the picture. We're at the sgrdstrand Hotel. We just booked into room 525. I'll be there. No one else, just me and the painting. Send the cavalry "I've got the picture. We're at the sgrdstrand Hotel. We just booked into room 525. I'll be there. No one else, just me and the painting. Send the cavalry.

"Now listen, "Hill went on. "The important thing is, Sid is back at the Grand, with the two villains, Johnsen and the other guy." "The important thing is, Sid is back at the Grand, with the two villains, Johnsen and the other guy."

"s.h.i.t! Okay."

"I'll ring you again as soon as I get to my room." Hill walked back toward Ulving. "Okay," he said. "Everything's fine. Sid'll give them the money."

"What should we do with the painting?" Ulving asked.

"Let's go look at the room."

The room was on the second floor. Hill asked Ulving if there was a set of stairs in back. Ulving showed him the fire escape. Hill wedged the door open with a fire extinguisher.

"Get the car and pull it around," Hill ordered. "I'll wait for you here." Even for Hill, this was a colossal-and pointless-risk. He didn't see it that way. Utterly confident that he knew his man, Hill figured it was impossible that Ulving would race off with his $70 million prize. The only danger Hill could see was that, in the course of driving from the front to the back of the small hotel, Ulving would find a way to crash his car.

Ulving pulled into view. Hill, still mortified that he had thumped The Scream The Scream on the headrest, lifted the painting from the car in slow motion. Then he dismissed Ulving. on the headrest, lifted the painting from the car in slow motion. Then he dismissed Ulving.

"Okay, I'll get a taxi back. Drive home safely."

Ulving, trembling with a night's acc.u.mulated tension, sped away.

Hill carried The Scream The Scream up the fire escape and into his room. He placed the painting, still wrapped in its blue sheet, on the bed. Then he locked the door, chained it, and shoved a chest of drawers in front of it. He scanned the small room. What else could he do to protect himself in case someone tried to s.n.a.t.c.h the painting? Hill looked out the window. Ten feet to the ground. If someone managed to get in, maybe Hill could grab the painting and make it out the window. Worth a try. He opened the window wide. up the fire escape and into his room.

Hill ran through the brief roster of people who knew where he was. Ulving. Would he send someone to do what he would never dare do himself? Probably not. The receptionist? She had seen Hill but not the painting. She shouldn't be a problem. The mystery man who had handed the painting to Ulving?

"f.u.c.k it! No one's going to take the painting," Hill said aloud. He unwrapped The Scream The Scream and propped it up on the bed, against the pillow. To his relief, he saw that the smack on the headrest hadn't made a dent. He stepped back for a better look, then sat in a chair and stretched contentedly. Sprawled at full length, Hill put his hands behind his head and contemplated the painting he had studied in so many books. and propped it up on the bed, against the pillow. To his relief, he saw that the smack on the headrest hadn't made a dent. He stepped back for a better look, then sat in a chair and stretched contentedly. Sprawled at full length, Hill put his hands behind his head and contemplated the painting he had studied in so many books.

Munch had hated the idea that one of his paintings could disappear "like a sc.r.a.p of paper into some private home where only a handful of people will see it." It was good to think that his greatest painting had been saved from a far darker fate.

Hill wasn't especially motivated by money. He couldn't have stayed a cop for twenty years if he had been. But, still, $70 million! Even more disorienting was to think that the piece of decorated cardboard on his bed had been copied and photographed and parodied and admired thousands and thousands of times.

Hill despised talk of Dr. No and his secret lair, but for several minutes he basked in the luxury of this private viewing. Not many people had ever had a chance to see a masterpiece in a setting like this. "Jesus!" he thought. "We've done it."

Itching to share his triumph, Hill phoned his contact at the Getty to give him the good news and thank him for his help. What time was it in California? Midnight? Anyway, n.o.body home. Hill left a cheery message. It was only eleven in the morning in Norway, but it was time to celebrate. On a small table in the room, the hotel had provided a bottle of wine. Hill poured himself a drink. Vile! He found a small bottle of Scotch in the mini-bar. Much better. Drink in hand, he spent another minute with The Scream The Scream.

Back to the world. When the good guys came to fetch him, Hill didn't want them accidentally hurting the painting. He wrapped it up again, laid it flat on the bed, and set the bra.s.s nameplates next to it.

Then he phoned Butler. When they had spoken just minutes before, Butler had whispered. Now he shouted down the line.

"Where's Sid? Charley, I can't find Sid."

Hill was as alarmed as Butler. "Oh, Christ," he said. "Something's happened. They've had an accident, something gone's wrong."

It didn't make sense. When Sid and Charley had driven away from the restaurant earlier in the morning, in separate cars, Sid had the shorter drive. He should have made it back to his room at the Grand Hotel long ago. Worse than that, Sid had headed straight back to Oslo. Hill and Ulving had made a longer drive and after that they had chased around forever to get the G.o.dd.a.m.ned picture.

Where was Sid?

The answer emerged soon enough. Unbeknown to Butler and Charley, Sid was was back at the Grand, in his room with Johnsen and Psycho. The Norwegian police team watching the hotel, whose job was to keep a sharp eye out for Walker and to contact Butler the instant they saw him, had managed to miss him. back at the Grand, in his room with Johnsen and Psycho. The Norwegian police team watching the hotel, whose job was to keep a sharp eye out for Walker and to contact Butler the instant they saw him, had managed to miss him.

Which meant that Walker was alone in a hotel room with two high-strung, violent criminals, and no one had the slightest idea where he was.

The three men did their best to pa.s.s the time. Psycho, whose real name was Grytdal, seemed to have taken a liking to Walker. He tried to strike up a conversation. The next day was his twenty-seventh birthday. Maybe someday he would travel to England and he and Walker could meet up. Maybe they could go fishing?

Walker played along, but everyone was preoccupied and the conversation kept sputtering out. Time dragged on, and the crooks grew jumpier. Walker rummaged in the minibar for something they could drink. Any minute now, the Norwegians knew, Hill should call Walker to say that he had The Scream The Scream and it was time to hand over the money. When was that G.o.dd.a.m.ned phone going to ring? and it was time to hand over the money. When was that G.o.dd.a.m.ned phone going to ring?

Instead of a ring, they heard a knock on the door. Sid went to see who it could be. Two men in street clothes, chatting nonchalantly. One carried a bulging sports bag that Walker recognized at once-his bag, with the money! In his other hand, the man held a steaming cup of takeout coffee with a roll balanced precariously on top. His companion stood clutching a hamburger and a c.o.ke. bag, with the money! In his other hand, the man held a steaming cup of takeout coffee with a roll balanced precariously on top. His companion stood clutching a hamburger and a c.o.ke.

The Norwegian cops, one more time. Somehow signals had gotten crossed yet again. The Norwegians had expected to find Walker alone in his room. Their plan-which had never been communicated to Walker-was that eventually the crooks would show up, Walker would produce the money, and a team of cops from the next room would swarm in and arrest the bad guys.

The two cops walked into the room. Johnsen jumped to his feet to see what the commotion was about. Grytdal lay sprawled across the bed. The cops looked at Grytdal and at Johnsen-they knew Walker, but not these two-and saw at once what they had walked into. "Police!" one of them shouted.

Grytdal leaped up from the bed and tackled the cop nearer to him. The bag with the money fell to the ground. Coffee splashed across the carpet. The second cop jumped in, fists flailing. Grytdal struggled to his feet and threw a bearhug around the cop he had tackled. The other, larger cop pounded Grytdal from behind. Grytdal, in a fury, seemed not to notice the blows falling on his back and head. Grytdal and the cop fell to the ground again and rolled across the carpet, neither man willing to let go. The bigger cop stuck close to the tumbling bodies. He looked like a referee in a wrestling match, but he was hoping for a chance to deliver a good, hard kick to Grytdal's head or ribs. The bag with the money lay unattended on the floor.

Walker and Johnsen had yet to join in. Dodging bodies, Walker grabbed Johnsen's leather jacket and flung it to him. "Let's run!"

The two men dashed out the door and down the hotel corridor. Johnsen spotted the emergency exit door that led to the stairs. Down he raced. Walker lumbered after him. Younger and faster than Walker, Johnsen soon left the detective alone in the hotel stairwell.

That wasn't ideal, but it wasn't the worst thing in the world. Walker hadn't had time to devise a polished plan-only a minute or so had elapsed between the Norwegians' knock on the door and the moment when the room became a cyclone of punching, kicking bodies-but fleeing the room wasn't a bad idea. Walker hadn't expected the Norwegians to drop by for a visit, but he did know that the cops had the hotel surrounded. If Johnsen did run, the cops ringed around the hotel should catch him.

The alternative-staying in the room and joining the free-for-all-didn't have much appeal. True, the cops would outnumber the bad guys three to two, but Grytdal's mania seemed to even the score. Walker was a rough customer himself, but he knew that Johnsen was younger and, more important, a kick-boxing champion. Better to run Johnsen out the door and into a trap than to barge into the melee.

Except that the police watching the hotel missed Johnsen as he ran out. With Johnsen gone, Walker raced back to his room. By the time he arrived the Norwegians had managed to handcuff Grytdal and radio for backup. Cops flooded into the hotel. They arrested Grytdal and dragged him off to police headquarters and took custody of the bag with the cash.

Johnsen, on the loose, took a moment to think things through. The police, he knew, were after him already. His fellow thieves would be after him, too. In many a police sting, one thief is allowed to slip away. For the police, the rationale is cold-hearted but straightforward. The thief's cronies would likely pin the blame for the arrests and the failed operation on the lone escapee, figuring that he had sold out his mates. Better to have the bad guys think they knew why things had gone wrong than to have them nosing around for an explanation. It wasn't quite fair, the cops might concede, but, then, life isn't fair.

Less than an hour after he fled the Grand, Johnsen picked up a phone and called Leif Lier, the Norwegian detective. The two were old acquaintances, and Lier had a reputation for fairness.

I need to come in, Johnsen said. Lier thought that seemed like a good idea. Johnsen summoned a taxi and rolled up to police headquarters in style. He had warned Lier that he didn't have money to pay the fare, but Lier had told him not to worry. This one would be on him.

At the sgrdstrand hotel, someone rapped loudly on the door to Charley Hill's room.

"Yeah?" Hill called.

Back came a shouted name and a word that sounded to Hill like "Politi!" Presumably the Norwegian for "police."

"Okay." Hill shoved the chest of drawers away from the door and opened it a few inches, though he left the chain on. He saw two men in street clothes, one of them tall and somber-looking, the other smaller, with curly hair. They held ID cards out toward Hill.

Cops, or a pretty good imitation. Hill opened the door. "Hi, I'm Chris Roberts."

One of the newcomers looked at the square parcel in the blue sheet lying on top of the bedspread. "Is that it?" "Yeah."

Hill unwrapped The Scream The Scream one more time. The cops stared. Then Hill rewrapped the painting and handed it to one of the cops. He handed the bra.s.s plates to the other. The three men headed downstairs. one more time. The cops stared. Then Hill rewrapped the painting and handed it to one of the cops. He handed the bra.s.s plates to the other. The three men headed downstairs.

Hill told the Norwegian cops to give him a minute. The hotel was perched on a fjord, and a pier stood nearby. Hill remembered Munch's painting of three girls on a pier, and he strolled out to the pier's end as a small sign of respect for the artist whose work had led him to this out-of-the-way town.

One of the cops kept a discreet watch. What was this crazy Brit up to now? What was this crazy Brit up to now? Hill didn't notice. He looked out across the water for a minute and punched a fist into the air in triumph. Then he broke into a celebratory jig. The Norwegian cop looked on-alone, at the end of the pier, a 200-pound bear of a man shuffled his way through a tentative and earthbound dance. Hill didn't notice.

The Norwegian cop looked on-alone, at the end of the pier, a 200-pound bear of a man shuffled his way through a tentative and earthbound dance.

That was mundane reality. On the movie screen that plays so often in Charley Hill's mind, the picture was different. There, his mission accomplished, the dashing detective leapt high into the air and spun halfway around in a joyful arc.

Epilogue.

In Norway, the National Gallery put together a triumphant press conference. The Scream The Scream was the star, and photographers pressed close for pictures. A hugely relieved Knut Berg, the museum's director, posed for photo after photo with his recovered masterpiece. Leif Plahter, the art restorer, beamed happily at the painting he knew so well. The Norwegian detective Leif Lier hailed his British colleagues. "We would never have got the picture back," he said, "if it had not been for Scotland Yard." John Butler made a few gracious remarks about the benefits of international police cooperation. Only Charley Hill and Sid Walker, phantoms whose visit to Norway was a state secret, missed the party. was the star, and photographers pressed close for pictures.

Back in England, the press celebrated. "Yard's Artful Dodgers Find The Scream," The Scream," the the Daily Mail Daily Mail crowed, and in their own, more sedate way, the "quality" papers cheered, too. Scotland Yard stood on the sidelines and pouted. Butler's television appearance in Norway had been replayed in Britain, and the police bra.s.s gave Butler a drubbing for his troubles. What was he doing flouncing around on television? What did that b.l.o.o.d.y painting have to do with police work?

Two years pa.s.sed before the trial began. In the meantime, Johnsen did his best to insure that Ulving, at least, would not forget him. The ex-con turned up at Ulving's hotel one day, drunk and angry, with a snarling pit bull on a thick leash. He demanded that the clerk tell Ulving that a friend of his had come to see him, and then he took a room, kicked a few holes in the wall, and collapsed in a stupor on the bed. Months later, he was back, this time at Ulving's summer cottage. Ulving was outdoors, sunbathing. Johnsen suddenly materialized, from a neighbor's yard. He had traded in the pit bull for a rottweiler. "What are you going to say in court?" he demanded.

By the time of the trial, the state had long since fit the pieces of the story together. The plot had been the brainstorm of Pl Enger, the soccer player turned crook, who had planned the theft in the confident hope that a buyer would turn up.

At the trial, Enger was charged with theft, and Grytdal and Johnsen with handling stolen property. A fourth man, William Aasheim, who had been only eighteen years old at the time of the break-in, was charged with theft, too. According to the prosecution, Aasheim and Enger were the two men with a ladder who had set the whole story in motion on a February morning in 1994. Enger and Grytdal, it emerged, were old colleagues. The two had done time in prison together for stealing Munch's Vampire Vampire.

Ulving, who had not been charged, saw to his relief that the prosecution case seemed strong even without him. For fear of retaliation, he did his best to keep his testimony vague and innocuous.

The trial began in Oslo, but Norwegian law forbade anonymous testimony. That seemed to rule out Hill and Walker. The two undercover detectives worked in a violent world; forcing them to reveal their true ident.i.ties in open court would have left them (and their families) sitting ducks for any crook with a gun and a grievance. In a compromise, the Norwegian court agreed to move part of the trial to London. There Hill and Walker gave their testimony from behind a screen, as "Chris Roberts" and "Sid Walker."

In January 1996, the judge read out his verdict. Guilty! Guilty! Guilty! Guilty! Enger, the ringleader, was sentenced to six years, three months; Grytdal, to four years, nine months; Aasheim, to three years, nine months; and Johnsen, to two years, eight months.

The four began serving their time but appealed their convictions. Conclusive as the evidence had been, a Norwegian appeals court ruled in favor of three of the four convicted thieves. All but Enger were set free. The court reasoned that, because Hill and Walker had entered Norway using false ident.i.ties, their testimony about what they had seen there was inadmissible.

Hill, never much impressed by the law's majesty (and always more concerned with paintings than with crooks), shrugged it off. With his customary refusal to allow mere logic to hem him in, he squeezed two contradictory responses into a single sentence and then dismissed the whole subject from his mind. "My personal view is that it's complete bulls.h.i.t," he said, "but it's the Norwegian system and you've got to respect it."

Enger is still in Norway, still proclaiming his innocence. (He managed to get his name in the papers not long ago, this time by buying, rather than stealing, a $3,000 Munch lithograph at an auction.) Grytdal is reportedly a pimp in Oslo, and Johnsen has died of a heroin overdose. In February 2004, Aasheim was murdered on the streets of Oslo.

Ulving, the art dealer, came out of the story triumphant and officially vindicated. Charley Hill, unswayed, consoles himself with the bittersweet knowledge that, once again, the system worked as poorly as he expected it would. Hill refuses to believe that Ulving was an innocent caught in a mess not of his making. Ulving, Hill speculates, "wanted to run with the hare and hunt with the hounds." He wanted, that is, to have it both ways. If the money from the artnapping had come through, he would have taken his share of the proceeds. If the crooks' plan fell apart, he would present himself as a patriot who had strived mightily to help his country recover one of its treasures.

The Norwegian authorities don't see it Hill's way. "I don't think Ulving was involved with the criminals," says Leif Lier, the detective. "He was used used by the criminals." The police had arrested Ulving on the day they recovered by the criminals." The police had arrested Ulving on the day they recovered The Scream The Scream, but they released him later the same day. For that arrest, Ulving won a judgment of about $5,000 against the state.

Today, Charley Hill is working as zealously as ever to find stolen paintings. Still a detective, he is out of the undercover game. He is on his own now, a detective-for-hire free to operate without layers of bosses to second-guess him. Characteristically, Hill paints the catch-as-catch-can life of a freelancer in the brightest of colors. "I'm a hunter-gatherer now," he exults, "and my family and I eat what I kill."

Some days the eating is better than others. Though Hill is not the only detective working full-time on recovering stolen art, he may be the only one who focuses almost exclusively on great great art. Given Hill's nature, the decision not to hedge his bets was inevitable. The coups, when Hill can pull them off, are colossal. In the summer of 2002, for example, he recovered t.i.tian's art. Given Hill's nature, the decision not to hedge his bets was inevitable. The coups, when Hill can pull them off, are colossal. In the summer of 2002, for example, he recovered t.i.tian's Rest on the Flight into Egypt Rest on the Flight into Egypt, which had been missing for seven years. The painting, worth something in the neighborhood of $10 million, had been stolen from the Marquess of Bath, a seventy-one-year-old ex-hippie and flower child, the author of a six-volume (so far) autobiography t.i.tled Strictly Private Strictly Private, and the owner of a 100-room estate that has been in his family for four centuries and sits amid grounds that cover 9,000 acres.

The ponytailed, bearded Lord Bath is an exotic creature who favors velvet jackets, dangling jewelry, and the company of striking women. He has had seventy-one "wifelets" to date, by his count, and keeps a portrait of each one on display in Longleat House. (Several of the flesh-and-blood women live in cottages dotted around the sprawling grounds.) "To some extent," Lord Bath boasts, "I pioneered polygamy in this country."

Lord Bath's insurance company announced that it would pay a 100,000 reward for the t.i.tian's return. Every swindler and nutcase in Britain phoned in tips. For seven lean years, Charley Hill chased leads. Eventually he pieced together a trail that led from one Irish Traveler clan to another and then to a dicey sports promoter whom someone in the second gang had had the bad judgment to shoot. t.i.tian's exquisite painting, which depicts Mary holding the infant Jesus while Joseph looks on approvingly, was apparently handed over in an attempt to smooth things over. (Hill likes to imagine the scene around the victim's hospital bed: "Sorry about the bullet. How about a picture of Joseph, Mary, and Jesus for all you've been through?") The promoter eventually decided he could do without this particular get-well card and shipped the t.i.tian off to a gang somewhere south of London. In the summer of 2002, Hill met an informant who claimed he knew where it had washed up. The story seemed to check out, though the thieves themselves were long gone, and Hill and his contact worked out a tentative deal.

On a hot August afternoon, Hill and the informant set out together. "So off they went," recalled Tim Moore, the manager of Longleat House, who had been working with Hill, "and I thought, 'Unless poor old Charles Hill is going to end up with a knife in his back or in a sack in the Thames, maybe we're on to something.' "

Hill drove. The informant gave directions. Eventually they pulled up to a bus stop. "There it is," said the informant. "The bag at the old man's feet."

Hill grabbed the bag, a shabby, blue-and-white plastic thing with a cardboard-wrapped package inside. He climbed back in his car, made a U-turn, and double-parked. He tore off a piece of the cardboard. Joseph's head, t.i.tian's brushwork. Bingo!

For his efforts, Hill earned 50,000, half the reward money. The other half went to the informant. And how did Lord Bath feel about the recovery? "I felt several million pounds richer."

Hill's decision to leave the police force was not a matter of walking away from a thriving enterprise. Police interest in art crime, never intense (except in Italy), is nowadays tepid at best. Undercover operations, in particular, take so much planning and involve so many people that they gobble up time and money in great chunks. The sting involving The Scream The Scream was not quite the grand finale of the undercover era in art crime, though it was close. That melancholy t.i.tle will likely rest with a sting in Madrid in June 2002, in which Spanish police and the FBI recovered $50 million worth of paintings that had been stolen from the home of a billionaire named Esther Koplowitz. was not quite the grand finale of the undercover era in art crime, though it was close. That melancholy t.i.tle will likely rest with a sting in Madrid in June 2002, in which Spanish police and the FBI recovered $50 million worth of paintings that had been stolen from the home of a billionaire named Esther Koplowitz.

Now that he is off the police force, Hill's acting days are over. His job these days is to work his underworld contacts in search of news about stolen paintings and then to negotiate their return. He knows who works which territory, which gangs steal paintings themselves and which hire local thieves to do the breaking-in, which gangs go for ladders and which prefer "ram raids" in which a driver crashes a car through locked doors.

His compet.i.tion have gone about things in a different way. The best-known are not individuals but small companies. One is called Trace; a compet.i.tor is Art Loss Register. Both work roughly on the model of matchmaking services. At the heart of each company's business is a vast, computer-searchable list of stolen paintings and furniture and the like, compiled from police reports and insurance claims. That list is compared, automatically, against the art and antiques on offer at countless auctions and art fairs and galleries. (Trace employs armies of typists on the Isle of Wight, where wages are low, to feed the computer listing after listing from an endless array of art catalogs and brochures.) When the computer red-flags a suspect item for sale, the companies step in to investigate. To find work better calculated to drive Charley Hill mad would take a long search.

The companies have different business models, but, in theory at least, they can make money in several ways: by charging a fee for listing stolen property in their database, by collecting a finder's fee if they make a recovery, by charging art dealers for access to their records (dealers are required to exercise "due diligence" to make sure they are not selling stolen goods).

It hasn't paid off yet. Trace is the pet project of an English billionaire and art collector, who can afford to swallow the considerable losses he has racked up. Art Loss Register says that its own losses will soon come to an end.

Both companies are small, but they are mega-corporations in comparison with the one-man band that is Charley Hill. (When he first left the police, Hill went into business with a partner, another ex-detective. The venture fared as poorly as anyone but Hill would have expected. The only relic of that short-lived era is a sign that Hill brought home and mounted on his bathroom door, identifying "The Charles Hill Partnership Meeting Room.") Hill figures that the freedom to set his own priorities is worth the financial risk he is running. Let someone else chase after silverware and stolen clocks. But the flip side of independence is isolation. Crooks are naturally not pleased to have Hill on their tail, and the cops are only marginally cheerier. The police see Hill as trying to show them up, and, in truth, that is not a role that would cause him many sleepless nights. "The police had seven years to get the t.i.tian back. And the simple fact is, they didn't get it back. Nor did the insurers through their various means. And I went out and cultivated people and got it back."

This is treacherous territory, pocked with ethical traps, as Hill is quick to acknowledge. Hill's underworld sources expect to be paid for their help. (The money comes from insurance companies or from the robbery victims.) The problem is getting those payments in the right hands or, more to the point, keeping them out of the wrong ones. Paying a reward to a source who has heard a rumor is one thing; paying a ransom to a criminal to buy back property he himself stole is another.

The police pay informants as a matter of course. The FBI's Ten Most Wanted list, for example, dangles rewards on the order of $1 million (and, in the case of Osama Bin Laden, $25 million). But in the case of stolen property, tradition held that money was paid only if arrests were made. Many police officials believe that rule should apply to stolen art. Do that, Hill insists, and stolen paintings will never be seen again. The police may talk about integrity, he says, but their real credo is indifference.

Hill's view, which is that in today's world freelancers will have to do what the police cannot trouble to do, has won him slews of enemies. Who is he to authorize rewards? More important, how can Hill know if his "informant"-whose own hands are supposedly clean-was in truth one of the thieves who stole the painting in the first place or, almost as bad, a fence who bought it from the thieves?

Despite his swashbuckling ways, Hill steps carefully here. He consulted Sir John Smith, the University of Nottingham law professor who was Britain's leading authority on the laws governing stolen property, and he has the great man's imprimatur. The two key principles, as spelled out by Smith, are that Hill must act on behalf of the owner of the stolen painting-he cannot go running around the country on his own authority-and he can't interfere with the police-he cannot make a deal where a crook hands over a painting in return for a Get Out of Jail Free card.
