When we finally stop, I almost cry in relief. Because we’ve found it, the double happiness place. Everything is familiar. The steel door, the red scaffolding, the distorted portraits, even the faded name on the facade, Ganterie, after the glove factory it must have once been. This is the place.

Toshi comes to the door, a tiny black girl with tight dreadlocks, and I want to hug her for delivering me to the white room. I want to march straight to the white room and lie down next to Lulu, to have everything feel right again.

I try to say this, but I can’t. I can’t even really get my legs to move because the ground beneath me has turned liquid and wavy. Toshi and my samaritan, whose name is Pierre, are arguing in French. She wants to call the police and Pierre says they have to help me find double happiness.

It’s okay, I want to tell him. I’ve found it. This is the place. But I can’t quite make the words come out straight. “Lulu,” I manage to say. “Is she here?”

A few more people crowd around the door. “Lulu,” I say again. “I left Lulu here.”

“Here?” Pierre asks. He turns to Toshi and points to his head and then to my head.

I keep repeating her name: Lulu, Lulu. And then I stop but her name continues, like in an echo chamber, like my pleas are traveling deep into the building and will bring her back from wherever it is she’s gone.

When the crowd parts, I think it really has worked. That my words dredged her up, returned her to me. That the one time I wanted one to wait, one did.

A girl steps out from the crowd. “Oui, Lulu, c’est moi,” she says delicately.

But that’s not Lulu. Lulu was willowy with black hair and eyes as dark. This girl is a petite china doll, and blonde. She is not Lulu. Only then do I remember that Lulu is not Lulu either. Lulu was the name I gave her. I don’t know her real name.

The crowd stares at me. I hear myself babbling about needing to find Lulu. The other Lulu. I left her in the white room.

They look at me with odd expressions on their faces and then Toshi pulls out her mobile phone. I hear her talking; she is requesting an ambulance. It takes me a minute to realize it’s for me.

“No,” I tell her. “I already have been to the hospital.”

“I would hate to see you before,” Wrong Lulu says. “Were you in an accident?”

“He got beaten up by skinheads,” Pierre tells her.

But Wrong Lulu is right. Accident—how I found her. Accident—how I lost her. You have to give the universe credit, the way it evens things out like that.

I take a taxi to Céline’s club. The fare eats into the last of my money but it doesn’t matter. I just need enough to get back to Amsterdam, and I already have a train ticket. On the short ride over, I nod off in the backseat and it’s only when we pull up outside La Ruelle that I remember we left Lulu’s suitcase here.

The bar is dark and empty, but the door is unlocked. I hobble down to Céline’s office. It’s dark inside there, too, only the grayish glow of her computer monitor lighting her face. At first, when she looks up and sees me, she smiles that smile of hers, like a lion waking from a nap, refreshed but hungry. Then I click on the light.

“Mon dieu!” she exclaims. “What did she do to you?”

“Was she here? Lulu?”

Céline rolls her eyes. “Yes. Yesterday. With you.”

“Since then?”

“What happened to your face?”

“Where is the suitcase?”

“In the storage room, where we left it. What happened to you?”

“Give me the keys.”

Céline narrows her eyes with one of her looks, but she opens a desk drawer and tosses me the keys. I unlock the door, and there’s the suitcase. She hasn’t come back for it, and for a moment I feel happy because it means she must still be here. Still be in Paris, looking for me.

But then I think about what the woman from Ganterie said, the one who came downstairs after my vision went all black and Toshi threatened again to call an ambulance and I begged for a taxi instead. This woman said that she saw a girl race out of the doors when she unlocked them this morning. “I called after her to come back, but she just ran away,” she told me, in French.

Lulu didn’t speak French. And she didn’t know her way around Paris. She didn’t know how to get to the train station last night. She didn’t know how to get to the club, either. She wouldn’t know where her suitcase is. She wouldn’t know where I was—even if she wanted to find me.

I take the suitcase, search for a luggage tag, and find nothing: not a name tag or an airplane baggage claim. I try to open it, but it’s locked. I pause for all of a second before yanking off the flimsy padlock. As soon as I open the bag, I’m hit with the familiar. Not the contents—clothes and souvenirs I’ve never seen before—but the smell. I pick up a neatly folded T-shirt, put it to my face, and inhale.

“What are you doing?” Céline asks, suddenly appearing in the doorway.

I slam the door shut in her face and continue going through Lulu’s things. There are souvenirs, including one of those wind-up clocks like one we looked at together at one of the stalls on the Seine, some plug adapters, chargers, toiletries, but nothing that tracks back to her. There is a sheet of paper in a plastic bag, and I pick that up, hopeful, but it only contains an inventory of sorts.

Tucked underneath a sweater is a travel journal. I finger the cover. I was on a train to Warsaw more than a year ago when my rucksack got nicked. I had my passport, money, and address book on me, so all the thieves got was a half-broken backpack with a bunch of dirty clothes, an old camera, and a diary inside of it. They had probably just thrown everything away once they’d realized there was nothing to sell. Maybe they got twenty euros for the camera, though it was worth a lot more to me. As for the diary, worthless; I prayed they tossed it. I couldn’t bear the idea of anyone reading it. It was the only time in the last two years I’d considered going home. I didn’t. But when I bought new things, I didn’t replace the diary.

I wonder what Lulu would think of me reading her journal. I try to imagine how I’d have felt had she read all my raw rantings about Bram and Yael from my stolen journal. When I do, it’s not the usual embarrassment or shame or the disgust that washes over me. Instead, it’s something quiet, familiar. Something like relief.

I open her journal, flipping through the pages, knowing I shouldn’t. But I’m looking for a way to contact to her, though maybe, I’m just looking for more of her. A different way to breathe her in.

But I find no scent of her. Not a single name or address: not hers, not anyone’s she met. There are only a few vague entries, nothing telling, nothing Lulu.

I flip to the end of the journal. The spine is stiff and cracks. Behind the back cover is a deck of postcards. I search them for addresses, but they’re blank.

I reach for a pen on one of the shelves and start writing my name, phone number, email address, and Broodje’s address for good measure, on each of the postcards. I write myself into Rome, Vienna, Prague, Edinburgh. London. All the while, I’m wondering why. Keep in touch. It’s like a mantra on the road. This act you do. But it rarely happens. You meet people, you part ways, sometimes you cross paths again. Mostly, you don’t.

The last postcard is of William Shakespeare from Stratford-upon-Avon. I’d told her to skip Hamlet and come see us instead. I’d told her the night was too nice for tragedy. I should have known better than to say a thing like that.

I flip Shakespeare over. “Please,” I begin. I’m about to write something else: Please get in touch. Please let me explain. Please tell me who you are. But my cheek is throbbing and my vision has gone all soft-focus again and I’m exhausted and weighted with regret. So I bookend the “please” with that regret. “I’m sorry,” I write.
