Paris wakes up slow on a Monday in October.

The cafés pull their chairs out one at a time. The street sweepers run their green brooms along the gutters. The pigeons stand on the stone lip of every fountain like old men waiting for a bus that is never going to come. And the light, that famous Paris light the painters crossed oceans for, comes up gray and soft over the river and lays itself across the rooftops like a blanket somebody forgot to fold.

I have seen that light from a lot of places. I have seen it from the deck of a barge, from the back of a taxi, from a hotel window with a cup of coffee going cold in my hand. But I had never seen it the way I saw it that morning, standing in the great square courtyard of the Louvre at a quarter to eight with my dog sitting at my left heel and the glass pyramid rising up in front of us like a jewel somebody had set down on the stones and walked away from.

Dale was not on a lead. Dale was never on a lead.

People notice that. In France they notice it more than most places, because the French love their dogs but they love their rules, too, and a big fluffy dog standing loose in front of the most famous museum on earth makes people look twice. A woman in a red coat walking a little gray poodle stopped dead about twenty feet away and stared at him. The poodle stared at him too. Dale looked back at both of them with that easy, open-mouthed grin of his, the one that makes him look like he just heard the best joke of his life, and then he turned his head away politely, the way a gentleman does when he has been caught looking at somebody across a restaurant.

The woman in the red coat decided he was harmless. She was half right.

He was wearing his everyday vest that morning, the red, white and blue one with the white stars across the shoulders and SERVICE DOG stitched along the side. His ID card was in the little clear pocket. Underneath it he was mostly white, a big, thick-coated collie cross with black ears and a black patch over each eye like a bandit in an old cowboy picture, and a black saddle across his back as if somebody had thrown a blanket over him and he had decided to keep it. When the wind came across the courtyard it lifted the fur on his chest and he closed his eyes into it and breathed in, long and slow.

That was the thing about Dale. He was always breathing in.

Most people breathe to stay alive. Dale breathed to find out what had happened.

“You’re doing it again,” my wife said.

Vasnti came back across the stones with two paper cups of coffee from the kiosk near the Carrousel arch, and she handed me one and kept the other close against her chest for the warmth. The wind had pulled some of her dark hair loose and she had given up on it. She was wearing my old green field jacket, which she claims she only borrowed and which I stopped asking for a long time ago.

“Doing what?” I said.

“Standing like that. Like you’re on guard. Feet apart. Hands behind your back. You look like you’re about to inspect the pyramid.”

“Maybe I am.”

“The pyramid passes,” she said, and she bent down and rubbed Dale behind the ears, and he leaned his whole weight against her legs and sighed like a balloon going down. “Doesn’t it, Dale? The pyramid is a very good pyramid.”

Dale agreed with her. He always agreed with her. In the long years he lived with us, I never once saw that dog disagree with my wife about anything, and I have to say that put him in a stronger position in our house than I have ever been in.

I drank my coffee and looked at the building.

You have seen the Louvre in pictures. Everybody has. But pictures shrink it. Pictures make it a postcard. Standing in the courtyard you understand that it is not a building at all. It is a city made of stone. The wings go out on either side of you for what feels like a mile, row after row of tall windows, carved faces, statues of men in robes standing in their niches looking down at you with blank stone eyes. Kings lived here. Revolutionaries marched through here. Napoleon held his wedding parade right across the square. And somewhere inside those walls, behind all those windows, there are about thirty-five thousand works of art and a lot of very nervous security guards.

They had reason to be nervous. One year ago to the day, four men had walked up to this building on a Sunday morning, in broad daylight, while visitors were already inside looking at the paintings, and they had stolen the crown jewels of France.

It had taken them less than eight minutes.

◆

I want to tell you about that morning, because it matters to everything that came after.

On Sunday, the nineteenth of October, a little after half past nine, a truck pulled up on the riverside road below the Louvre’s long southern wing. It was the kind of truck you see all over Paris, a furniture mover’s truck with an extending ladder lift on the back, the sort they use to swing sofas and pianos up to fourth-floor apartments because the staircases in old Paris buildings were built for people who owned one chair and a candle. Nobody looks twice at a truck like that in Paris. They are as common as pigeons.

Two men in yellow high-visibility vests climbed into the basket at the end of the lift. The lift raised them up the face of the old stone wall to a balcony on the first floor, outside a tall window. Behind that window was the Galerie d’Apollon, the Gallery of Apollo, one of the most beautiful rooms ever built by human hands. Its ceiling is painted with gods and suns and horses. Its walls are covered in gold. And in that gallery, in glass cases, sat what was left of the jewels of the kings and emperors of France.

The men cut through the window. They went inside. Visitors screamed and ran. Guards came, but the men had power tools, angle grinders with spinning discs that sent sparks across the polished floor, and they cut straight into two of the display cases. They took what they had come for. They climbed back out the window and down the lift and onto two motor scooters where two more men were waiting, and they went off along the river into the Sunday traffic, and Paris swallowed them whole.

Behind them, on the ground, they left the crown of the Empress Eugénie, the wife of Napoleon III. One of them had dropped it in the hurry. It was bent and crushed, but it was there. It was the only thing that came back.

Everything else was gone. Eight pieces. A sapphire tiara and a sapphire necklace and a single sapphire earring that had belonged to two queens of France, Marie-Amélie and Hortense. An emerald necklace and a pair of emerald earrings that Napoleon himself had given to his second wife, Marie-Louise, as a wedding present. Two brooches that had belonged to the Empress Eugénie, one of them a great bow of diamonds that she used to wear across the front of her gown. And her tiara, set with pearls and diamonds, that she had worn the year she was married.

The newspapers said the jewels were worth eighty-eight million euros. The people who loved them said that number was an insult. You could not put a price on them, they said, any more than you could put a price on the Eiffel Tower or the river or the bells of Notre-Dame. They were a piece of the country’s history, and somebody had cut them out with a power tool on a Sunday morning and ridden away on a scooter.

In the weeks after, the police did good work. I want to say that clearly, because some of what comes later in this story might make you think otherwise. They arrested the four men who had done the job. They found them through DNA left on the glass and on the things they had dropped. Those four men went to prison to wait for trial.

But not one of them said where the jewels had gone. And nobody ever found the person who had sent them.

That was a year ago. In July, the Gallery of Apollo opened again to the public. The visitors went back in and looked up at the painted ceiling and the gold walls. But the glass cases where the crown jewels had sat were gone. The jewels that hadn’t been stolen had been moved to somewhere safer. The room was beautiful and empty, like a church after the funeral.

I had read all of it. I had read it slow, the way I read everything, with my finger under the line and the reading app on my phone saying the hard words out loud into my ear. I am dyslexic. I’ll tell you about that properly later, because it is part of who I am and I am not ashamed of one inch of it. For now, just know that when I want to understand something, I don’t skim it. I can’t. I take it in one word at a time, and maybe because of that, the words stay.

And the thing that had stayed with me, the thing I could not stop thinking about for a year, was that I had been inside that gallery.

I had walked through it with Dale.

◆

It was years ago now. Dale was in his prime and so was I, or near enough.

Dale had been a British Ministry of Defence Police dog before he ever came to live with me. MWD 4007. That was his number, his badge, the way his country knew him. His trade was explosives and firearms. He had worked bases and docks and airfields and royal events, and the men who trained him said he was the finest nose they had ever put through the program. When he retired, he came to me, and I took over as his handler, and for a good stretch of years after that, when there were jobs that needed a dog like Dale, the two of us did them together.

One of those jobs was the Louvre.

There was an important visit coming. I won’t say whose. Some foreign leaders and their wives and a long line of black cars, the kind of afternoon that has security people up for three nights straight. The French had their own dogs, of course, and good ones, but this visit had British and American people involved too, and somebody somewhere decided an extra team would not hurt. So one morning before dawn, before the museum opened, Dale and I came through a side door off the riverside road and spent seven hours walking every room the visitors would see.

I remember the quiet most of all. A museum with no people in it is the quietest place on earth. Your boots sound like gunshots on the parquet. You can hear the old building ticking and settling around you, the way a house does at night. The paintings watch you. I am not a superstitious man, but walking past the long faces in the Grand Gallery in the half dark, with only the security lights on, I felt like every one of them knew exactly what I had for breakfast.

Dale did not care about the paintings. Dale cared about the air.

I would give him the signal, two fingers pointed at the wall, and he would go along it with his nose about two inches from the baseboard, working left to right, high and low, under benches, behind the velvet ropes, around the feet of statues. He never hurried and he never dawdled. He moved like water finding its way downhill. When a room was clean, he came back to my left side and looked up at me, and I said, “Good boy,” and we went on to the next.

We had a young French police officer with us that day as our escort. She was maybe twenty-five or twenty-six, very serious, with her hair pulled back so tight it looked like it hurt, and she spoke better English than I spoke French and made sure I knew it. She had been told to walk with the American and the dog and make sure we didn’t touch anything. I don’t think she was very happy about it. I think she thought it was a job for somebody less important than she intended to become.

Her name was Hélène Marchand. I remember because she said it like a challenge.

The Gallery of Apollo came late in the morning. I remember coming through the doors and stopping. Even Dale stopped. The ceiling went up and up, all gold and painted sky, and the morning light came through the tall windows and hit the cases in the middle of the room, and inside those cases the jewels caught fire. I have never been a man for jewelry. I wear a watch and my wedding ring and that’s the end of it. But I stood in that doorway and I understood, for the first time in my life, why people had fought wars over shiny stones.

There was the Empress’s crown, gold eagles standing around the rim with their wings spread. There were the emeralds, green as a pond in summer. There was a tiara of pearls that looked like it had been made from moonlight.

“Well,” I said. “Somebody’s grandmother had nice things.”

Officer Marchand gave me a look that could have frozen the river.

Dale worked the gallery like he worked every room. He went along the walls, under the windows, around the cases. When he passed the case with the Empress’s things in it, he slowed down a little and lifted his nose, and I watched him, because I always watched him. But he kept going. Nothing there. He came back to my side and I told him he was a good boy, and we moved on.

It was in the service corridor on the way out, an hour later, that he found something.

◆

It was a cupboard. Just a gray metal cupboard set into a wall in a back corridor where the cleaners kept their mops. The kind of thing nobody looks at twice. We were walking past it toward the next stairwell, not even searching, just moving, and Dale stopped.

He did not bark. Explosive dogs don’t bark when they find something. You don’t want a dog that barks and jumps and scratches at a thing that might go bang. Dale’s signal was quiet. He sat down, square in front of the cupboard, and he went still. Completely still. His nose pointed at the crack under the cupboard door like the needle on a compass, and his eyes fixed on it, and he did not move a hair.

I had seen him do that perhaps a dozen times in all the years we had worked together. Every time, my heart had done the same thing it did that morning. It went cold and slow and very clear.

“Back up,” I said to Officer Marchand, quietly.

“What is it?”

“I don’t know yet. Back up. Slowly. Down the corridor. Get on your radio.”

To her credit, she did not argue. All that stiffness went right out of her and she did exactly what I said, and she did it fast. In ten minutes the corridor was cleared and there were men in heavy suits coming up the back stairs, and in forty minutes they had the cupboard open.

There was no bomb. I want to tell you that straight away, so you can breathe. But there was a cardboard box on the bottom shelf behind the mop buckets, and in it was a mess of old theater flares and a bag of blank cartridges, the kind film crews use to make guns go bang on screen. Months before, there had been a film shoot in that part of the museum, and somebody on the crew had shoved the box in a cupboard at the end of the day and forgotten it.

Harmless, mostly. Old and forgotten and stupid. But they were explosives, and they were cartridges, and they were sitting in a cupboard a few hundred feet from where some of the most important people in the world would be walking that afternoon. Nobody had known they were there. Nobody, except Dale.

The men in the heavy suits carried the box away. Officer Marchand stood looking at the empty cupboard. Then she looked at Dale. He was sitting at my left heel again, panting gently, grinning at her.

“How did he know?” she said.

“That’s his job,” I said.

“Through a closed door? Behind all those buckets? With the cleaning chemicals?”

“He doesn’t smell what’s in the way,” I said. “He smells what’s underneath.”

She didn’t say anything. But I saw something change in her face.

Then Dale did the thing that I believe made Hélène Marchand remember us for all the years that came after.

I had already given him his reward, a few minutes with his favorite tennis ball, which was the only pay he ever wanted. He’d had his ball and he’d given it back. We were supposed to move on. But he wouldn’t. He kept looking down the corridor, back the way the delivery men must have come. He kept lifting his nose and whining, very softly, which he almost never did.

So I gave him the command. It was one his old British trainers had built into him, a thing they said maybe one dog in a thousand could really do.

“Dale,” I said. “Back track.”

He put his nose down on the floor where the box had been carried out, and he went. Down the corridor. Through a fire door. Down two flights of service stairs that smelled of floor polish and old dust. Across a loading bay. Out a steel door into the delivery yard, which was gray and cold and full of vans. And he walked along the line of vans with his nose working, past one, past two, past five, and he sat down in front of a white van with a dented back door and a film company’s name painted on the side, half covered by a magnetic sign for a plumbing firm.

Inside that van, the police found two more boxes of flares and blanks, and a set of keys to a storage locker across the river, and in that locker they found enough old film-effects powder and pyrotechnics to make the security people go very pale indeed. None of it was meant for harm. It was a sloppy, careless little company cutting corners and storing its effects where it should not have stored them. But it should never have been inside the Louvre, and nobody would ever have known where it came from if a big fluffy collie cross had not walked them straight to it.

“He followed the smell back,” Officer Marchand said, when it was all over and we were standing in the yard drinking terrible coffee out of plastic cups. “From the box to the van. Through the whole building.”

“He follows it back to where it came from,” I said. “That’s his gift. Most dogs can find the thing. Dale can find where the thing was before.”

She looked down at him for a long time.

“In France,” she said finally, “we would say he has a nose for history.”

I liked that. I’ve always remembered it.

◆

So that was what I was thinking about, standing in the courtyard with my coffee one year to the day after the robbery, with the wind coming across the stones and the first tourists beginning to gather by the pyramid with their phones held up in front of them.

The anniversary had brought out the news crews. There were three television vans parked over by the Pavillon de Flore, and a pretty reporter in a camel coat was standing in front of the museum doing her piece to the camera, waving her hand toward the long southern wing where the thieves had gone in. A small crowd had stopped to watch her. Some of them were taking pictures of her, and some were taking pictures of the building, and one little boy in a yellow raincoat was taking pictures of Dale, which showed that at least one person in that courtyard had his priorities straight.

Dale sat for the boy very politely. He even tilted his head. He knew perfectly well what a camera was.

“Robert,” Vasnti said quietly. “There’s a woman watching you.”

I didn’t turn around. Old habits. I lifted my coffee cup and looked over the top of it, the way you would if you were just looking at the view, and I let my eyes drift along the edge of the crowd.

She was standing by one of the low stone fountains at the edge of the courtyard, maybe fifty yards off. A woman in her middle forties, in a long navy raincoat, hands in her pockets. Dark hair cut short to the jaw. She wasn’t watching the reporter and she wasn’t watching the pyramid. She was watching me. And she was chewing on something, slowly, the way people chew when they are thinking about something else entirely.

“How long has she been there?” I said.

“Since before I came back with the coffee. She came from the direction of the river. She stopped when she saw Dale.”

I looked at Dale. Dale had seen her too. His ears were up, both black triangles pointed toward the fountain. He wasn’t worried. If he had been worried I would have known it, because his whole body would have gone quiet and still in a way that it only did when he was deciding whether somebody was a problem. No, this was something else. His tail was moving, very slowly, side to side across the stones.

He knew her.

“Well,” I said. “I’ll be.”

The woman in the raincoat took her hands out of her pockets and started across the courtyard toward us. She walked like a police officer, and I don’t know how else to explain that to you except that once you have been around a lot of police you can see it. Square shoulders. Weight on the balls of the feet. Eyes moving everywhere and stopping nowhere. She came straight through the edge of the crowd and stopped about six feet away, and she looked down at Dale, and something in her face that had been held very tight for a very long time let go a little.

“Bonjour, Dale,” she said.

Dale stood up, walked to her, and pushed his nose into her hand.

She crouched down right there on the wet stones in her good raincoat and put both her arms around his neck. He let her. He let her hold on as long as she wanted, and he leaned into her, and his tail went all the way around in a circle the way it did when Vasnti came home after a long trip.

Vasnti looked at me with both eyebrows up.

“Robert,” she said. “Who is this?”

The woman stood up. Her eyes were wet and she wiped them with the back of her hand without any embarrassment at all, and then she put the hand out to me.

“Capitaine Hélène Marchand,” she said. “Brigade de répression du banditisme. You will not remember me, Monsieur Hethcoat. It was many years ago. I was very young and very rude to you.”

I took her hand. I looked at her face. Under the lines and the short hair and the tiredness around the eyes, I saw her, the girl with the hair pulled back too tight who had told me not to touch anything.

“I remember you,” I said. “You were not that rude.”

“I was extremely rude.”

“You were a little rude.”

“I thought you were a tourist with a dog,” she said. “I thought somebody had sent me to babysit an American cowboy so the real police could do the real work.” She looked at Dale again and her mouth twitched. “Then he found the cupboard.”

“Then he found the cupboard,” I agreed.

“I have told that story at many dinners,” she said. “Nobody believes it. The dog who followed the smell all the way back to the van. My colleagues think I am making it up.” She turned to Vasnti and held out her hand. “Pardon. Madame Hethcoat?”

“Vasnti,” my wife said, and shook her hand. Then, because she is who she is, she said, “You look like you haven’t slept in a month.”

Marchand laughed, a short surprised laugh, and for a second she looked twenty-five again.

“A year,” she said. “Not a month. A year.” And then the laugh went away, and she looked over her shoulder at the reporter in the camel coat, still talking to her camera with her hand waving at the long southern wing. “I came here this morning because of the anniversary. I don’t know why. Perhaps to punish myself. Perhaps because I hoped the building would tell me something it has not told me in twelve months. And then I saw a big white dog with black ears sitting in front of the pyramid with no lead, and I thought I was going mad.”

“You’re on the case,” I said. It wasn’t a question.

“I was on the case,” she said. “I am still on the case, officially. There is a team. There are files. There are boxes and boxes of files.” She put her hands back in her pockets and took out a little paper packet and held it out. It was licorice. Black licorice twists, the old-fashioned kind. “I stopped smoking,” she said. “This is worse for my teeth but better for my lungs. Please.”

I took one to be polite. Vasnti took two, because she likes licorice, which I have never understood in all our years of marriage.

“We caught the four men,” Marchand said. “You read about it, I am sure. The men on the lift and the men on the scooters. Good work. Very good work, very fast work. I am proud of it.” She chewed. “And they have not said one useful word. Not one. They sit in their cells and they wait for their trial and they look at the wall. We offer them deals. We tell them that if the jewels come back, it will help them. The prosecutor goes on the radio and says, please, give them back, there is still time. Nothing. It is as if somebody has sewn their mouths shut.”

“Somebody’s scaring them,” Vasnti said.

Marchand looked at her sharply. Then she nodded.

“Yes. That is what I believe. Somebody is scaring them more than prison scares them. Somebody sent them. Somebody paid for the truck and the scooters and the grinders and told them which window and which cases and which pieces. Somebody is sitting somewhere with the crown jewels of France in a box, and he is not afraid of me at all.”

The wind came across the courtyard again and lifted Dale’s fur. He put his nose up into it.

“And the jewels?” I said.

“Gone. Eight pieces. We have watched every dealer in Antwerp and Amsterdam and Geneva and Tel Aviv and Dubai. Interpol has them on every list. The experts say they cannot be sold, they are too famous. The experts say they might already be broken up and the stones cut down so no one can recognize them, and the gold melted. The experts say a great many things.” Her jaw tightened. “I do not believe they have been broken up.”

“Why not?”

She looked at me for a long moment, as if deciding something.

“Because of the crown,” she said.

“The one they dropped.”

“Yes. Everyone says, how lucky, the thieves were clumsy, they dropped the most famous piece in their hurry. The crown was damaged, but the Louvre has restored it. It is almost perfect again. Except for one thing.” She held up a finger. “The crown had eight golden eagles around its rim. When we picked it up off the ground, there were only seven. One eagle was gone. Broken off. We searched every centimeter of that pavement and the gutter and the drains. We never found it.”

“So somebody picked it up,” Vasnti said.

“Somebody picked it up,” Marchand said. “Somebody who was running from the police with millions of euros of jewels in a bag stopped to pick up one little gold eagle off the road. Why would a man do that? A man who only wants money does not stop for a broken piece of a crown he has just dropped. He runs.”

“Unless the man who sent him told him not to leave a single piece behind,” I said slowly.

“Unless the man who sent him,” Marchand said, “is not a man who wants money.”

None of us said anything for a minute. The little boy in the yellow raincoat had moved on and was photographing a pigeon. The reporter had finished her piece and was laughing at something her cameraman said, her coat flapping in the wind. Across the courtyard, the museum guards were pulling open the glass doors of the pyramid for the first visitors of the day.

“Why are you telling me this?” I said.

Marchand did not answer right away. She crouched down again and put her hand on Dale’s head, and he closed his eyes.

“Because I am tired, Monsieur Hethcoat,” she said. “Because my commandant wants this case to go quietly into a box until the trial, and then he wants the trial to be the end of it. Because on the first of November I will be moved to another case, a very important case about stolen cars that nobody cares about, and the crown jewels of France will become a file that nobody opens. Because I have looked at every piece of evidence we have a hundred times and I cannot see anything new.” She looked up at me. “And because once, many years ago, I watched your dog find something that twenty trained men had walked past. And then I watched him take it back to where it had come from.”

“He’s retired,” I said. “He’s been retired a long time.”

“So I have heard,” she said. “Has he forgotten?”

I looked at Dale. He opened his eyes and looked at me. They were dark brown, those eyes, deep and steady, and there was a lot in them. There always was. People who don’t know dogs think they are simple. People who knew Dale knew better.

“No,” I said. “He hasn’t forgotten anything.”

“Neither have I,” Marchand said, and she stood up. “There is a bag. In our evidence store. A sports bag, black, very ordinary. A street cleaner found it in a bin near the Porte de Bagnolet nine days after the robbery. It was empty. Torn lining. No fingerprints. Our dogs smelled it and found nothing, and our laboratory tested it and found nothing, and it has been sitting on a shelf ever since with a label on it that says ‘not connected.’”

“But you think it is connected.”

“I think,” she said, “that the thieves were seen on the cameras on the riverside road carrying two black sports bags. Exactly this kind. I think one of them ended up in a bin by the edge of the city, and I think nobody has ever been able to tell me how it got there or where it was before.” She tilted her head toward Dale. “And I think there is only one nose in all of France that might be able to tell me where that bag has been.”

I didn’t say anything.

Vasnti did. Of course she did.

“He’d love it,” she said. “Look at him, Robert. He’d love it.”

I looked at him. Dale was sitting very straight now. His ears were up. His nose was working, and he was looking from me to Marchand and back to me, and his tail had stopped moving. It wasn’t that he understood the words, though I have never been sure how many words he understood. It was that he understood the feeling. He had felt it in hundreds of rooms and on hundreds of mornings. Somebody needs you. There is work.

He had been retired a long while. He had spent those years being the best friend I ever had, and sleeping across the foot of our bed, and flying across oceans in his own little space by the airplane window, and chasing sticks into the sea on long gray beaches, and never once complaining. But every now and then, when we walked past a police car or an airport security line, I would see him lift his head and watch the working dogs go by, and I would see something in his face that I can only call homesickness.

“He’s not a police dog anymore,” I said. “Neither am I. I’m a Marine, and I’m a travel planner, and I’m a husband. I take people on walking tours of the Marais and tell them where to get the best falafel. I don’t have any authority in France. Your commandant won’t want me anywhere near his case.”

“No,” Marchand agreed. “He will hate it. He will hate you. He will say you are an American tourist with a pet and that the BRB does not need help from foreigners with dogs.” She smiled for the first time, a real smile, a little crooked. “This is why I will not ask him.”

Vasnti laughed out loud.

“I can get you into the evidence store,” Marchand said. “Tonight. After seven, when the day team goes home and there is only the night clerk, and he owes me a favor. One hour. You, the dog, the bag. If Dale smells nothing, I will buy you both the best dinner in Paris and I will never bother you again. I will go and find stolen cars and grow old and tell my story about the cupboard at dinner parties.”

“And if he does smell something?” I said.

She looked at the museum. The guards had the doors open now. The first visitors were going down the escalator into the glass pyramid, small and dark against all that light.

“Then,” she said, “perhaps we find out who has been sitting in the dark with the crown jewels of France for a year, laughing at all of us.”

The wind dropped. The courtyard went still. Somewhere over by the river a church bell started ringing eight o’clock, and then another joined it, and another, until it seemed like every bell in Paris was ringing the hour.

I looked down at Dale. He was already looking up at me.

I have never known whether a dog can make a decision. I know that I did not decide anything that morning. I just looked into those dark brown eyes, and I saw what was in them, and I knew.

“Seven o’clock,” I said.

Capitaine Marchand let out a long breath. She nodded once, sharply. Then she gave Dale one more rub between the ears, said something soft to him in French that I didn’t catch, and walked away across the courtyard with her hands back in her raincoat pockets. She did not look back. Police officers never do.

Vasnti put her arm through mine.

“You were always going to say yes,” she said.

“I didn’t say yes. I said seven o’clock.”

“Robert Hethcoat,” my wife said, “I have been married to you a long time, and I have never once heard you say anything else but yes to a dog who needed you.”

I didn’t argue. There didn’t seem to be much point.

Dale stood up, shook himself from his nose to his tail so that his fur stood out like a dandelion, and then he looked toward the long southern wing of the Louvre, where the thieves had gone in a year before. He looked at it for a long time with his nose lifted into the wind. I don’t know what he smelled. I don’t know if, after a whole year, there was anything left to smell at all.

But I’ll tell you this. When we finally turned to go, he didn’t want to leave. He kept stopping and looking back over his shoulder, the way he had looked back down that service corridor all those years before.

As if something in that great stone building was calling to him.

As if it had been waiting a whole year for him to come back.
