An elderly woman turns toward me. She comes closer along the pew and says, “I’m glad that you’ve come.” Her white hair frames her head like a halo. She says, “You know that wonderful passage? It’s always been my favourite. ‘In my Father’s house there are many rooms.’”

I feel myself trembling.

“You’ve been drinking,” she says, compassionate. “Many of your people have this illness. But you’ve come home now. It will be all right.”

I tell her that she is wrong, that even though we are surrounded by the sea, there is nothing to drink. Yet the salt water is seeping into our skin, swelling our bodies, making us unfit for land. “You know,” I say. “Don’t you?” The woman hesitates, then she looks down at the boy in my lap who is nothing but a knotted, filthy scarf. Red-chequered, tattered. I unfold it and try to smooth the scarf against my legs. “I tried to save him,” I tell her. “I tried to keep him from drowning.” She looks up toward the high altar, the glowing lights, Jesus illuminated on his cross, then she gazes at me with understanding in her eyes. Sometimes it’s pity, undeserved as it is, that hurts me most.

When the unthinkable happened, I had gone to Hiroji’s apartment. Years ago, when he was travelling more frequently, he had given me a copy of his keys so that I could take care of Taka the Old. For nearly a month now I have slept on his couch, leaving the curtains open as if I believe he will re-enter through the unlatched windows. I know that he is in Cambodia, the place where his brother, James, was last seen. There is no other place he would go. I imagine him unpacking his suitcase, telling me what he has learned, all the things he has seen: the Tonle Sap reversing its waters, the sprawling jungle, bats high in the shadows of the caves. He will tell me how to accept this life. I dream of returning home, not only to the place of my birth but to my son. My mother who died without me, who died so long ago, will finally close her eyes. She will turn her gaze from this world, she will slide like a boat up against land, into her future.

In the morning, I walk to Kiri’s school. From Monday to Friday, I see my son once each day, we meet in the playground before school begins. This is the routine Navin and I have worked out. It is an interim measure, we have both said. A way forward.

When I arrive, Navin is already there, leaning against the fence. I go to stand beside him. He touches my cheek. For a brief moment, his lips are warm against mine. “You didn’t sleep last night,” he says.

I tell him that I did, a little, enough. My hands are icy and Navin takes hold of them. He says that I look exhausted, that I should take some time off. “It’s okay,” I tell him. Work gives me a feeling of order, of cheer. He kisses my frozen fingers, and the kindness that I have always loved in him, that he gives so freely, washes over me. But Navin, too, is worn out.

I say again, “It will be okay.”

In the playground, there are so many snowsuits in so many primary colours that my vision is temporarily dazzled. I stand at the fence and search the kaleidoscope for Kiri. There he is. I see him now, I see him. My son races across the grounds, a cub in a pack of awkward pups, pursuing a soccer ball. When his team scores, he howls with joy. The pink sky burns around us. Kiri chases the soccer ball, he tussles, fights, drops his hat, picks it up, and waves it like a flag.

“Did you get my message,” Navin asks. “About Vancouver?”

I nod. “When will you go?”

“Next week, if I can pull everything together.” He says he is just finishing up a project, a new building design, but his colleagues can oversee it. He thinks the distance will be good for Kiri. He says that Kiri keeps asking when I’ll be coming home. “I’ll talk to him,” I say. We are surrounded by parents and children, by the rippling joy of the playground. Navin begins to say something but just then Kiri glimpses us. He runs forward. A girl stops him. “Kiri! Kiri!” she calls.

“I’m a caterpillar,” he says.

She frowns, “No! You’re not.”

“I’m a worm,” he says charmingly, and the girl waves both arms in kind of Hawaiian dance.

Kiri comes to me. I kneel down and he tells me, in a rush of words, that he’s going to visit his Auntie Dina later, they’re planning to build a rocket park, that she’ll make him murtabak and roti canai, that her dog, Bruno, is kind of old and shuffles very slowly. Kiri has taken to speaking quickly now, as if he is afraid he will run out of time. As if he will be too late.

“Will you build a moon?” I ask him, kneeling in the snow. I busy myself readjusting his hat, which has fallen between his neck and the collar of his coat.

“Oh!” he says, surprised. “Good idea.”

“What about moon boots?” Navin says. “Moon cakes?”

Kiri frowns.

“Moonlight,” I say.

My son frees his hands and begins buttoning my coat up, all the way to the top. “Don’t get cold, Momma,” he says. I promise that I won’t. His mittens, attached to his coat, swing back and forth like a pair of extra hands.

I kiss them both goodbye. They walk through the schoolyard, up the front steps of the building. Navin turns back, watching me, love and pity in his eyes. They go on, Kiri’s hat bobbing up and down. In this way, my son is embraced by the glow of the school. Snow hurries forward to lay its thin white sheet over the teeter-totters, the swings, and the monkey bars. Through the big windows, I can see a movement of colours, children swirling around one another. Even at the edge of the schoolyard, I can hear their voices.

I catch the 535, heading downtown. The man next to me is nodding off to sleep, his body propped up by his fellow passengers. When the bus jumps, startling him awake, he looks up, surprised to see us. Rivulets of melted slush glide back and forth along the floor. In our heavy boots, we step daintily through the muck.

We arrive at my stop and I exit through the back doors. Above me, in the clearing sky, pigeons roost on the high wires, clouds descend, and I turn and walk east along the frozen skirts of Mount Royal. The mountain, dipped in snow, has an eerie beauty, tree after tree rising up the hill, slender as matchsticks. The temperature is dropping fast and people, blank-faced beneath their hats and scarves, shoulder roughly by. This place wears its misery so profoundly. Mean-eyed women, sheathed in stiletto boots, kick the ice aside while small men in massive coats lumber down the sidewalk. The elderly fall into snowbanks. All human patience curdles in the winter. On University Street, I turn left, continuing until I reach the heavy doors of the Brain Research Centre.

Sherrington, Broca, Penfield, Ramón y Cajal: in the atrium of the building, the names of our scientific forebears are etched in gold lettering along the wall. The wide hallways buzz with fluorescent light. Rather than going downstairs to my lab, I climb the stairs to the airy fourth floor where the clinicians hold court. The morning neurology and neurological surgery rounds are already underway and this hallway is temporarily deserted. I come to Hiroji’s office. In January, the brc disabled his code but not the code of our laboratory group. When I punch in the numbers, a green light blinks fleetingly before some mechanism clicks. I turn the knob and enter.

Here is Hiroji’s window with a view of the mountain. Here is his desk.

I step inside, shutting the door behind me. File cabinets range against the right-hand wall, all the way to the ceiling. Morrin, the head of our research unit, has been pushing me to move our shared files from Hiroji’s office, but I hadn’t yet gotten around to it. I thought that, by the time I organized everything, Hiroji would be back and then the files, too, would have to return. There seemed no point in even beginning. The cabinets whine when I open them. Half of the contents are already gone, all the patient files have been moved elsewhere, but the entire history of our collaborative work remains, perfectly ordered.
