“Did you ever use the phrase ‘in the mix’?”

“I don’t think so. No. I wouldn’t have.”

“I hated that one especially.” Garrett was studying the report.

“Oh, I didn’t mind it so much. It made me think of baking. My mother would buy these cookie mixes sometimes when I was a kid.”

“Do you remember chocolate-chip cookies?”

“I dream of chocolate-chip cookies. Don’t torture me.”

Garrett was quiet for so long that Clark opened his eyes to make sure he was still breathing. Garrett was absorbed in watching two children playing on the tarmac, hiding behind the wheels of the Air Canada jet and chasing one another. He’d become calmer over the years but remained prone to episodes of unfocused staring, and Clark knew by now what his next question would be.

“Did I ever tell you about my last phone call?” Garrett asked.

“Yes,” Clark said gently. “I believe you did.”

Garrett had had a wife and four-year-old twins in Halifax, but the last call he’d ever made was to his boss. The last words he’d spoken into a telephone were a bouquet of corporate clichés, seared horribly into memory. “Let’s touch base with Nancy,” he remembered saying, “and then we should reach out to Bob and circle back next week. I’ll shoot Larry an email.” Now he said the words “Circle back next week” under his breath, perhaps not consciously. He cleared his throat. “Why did we always say we were going to shoot emails?”

“I don’t know. I’ve wondered that too.”

“Why couldn’t we just say we were going to send them? We were just pressing a button, were we not?”

“Not even a real button. A picture of a button on a screen.”

“Yes,” Garrett said, “that’s exactly what I’m talking about.”

“There was not, in fact, an email gun. Although that would’ve been nice. I would’ve preferred that.”

Garrett made his fingers into a gun and aimed it at the tree line. “Ka-pow!” he whispered. And then, louder, “I used to write ‘T-H-X’ when I wanted to say ‘thank you.’ ”

“I did that too. Because, what, it would’ve taken too much time and effort to punch in an extra three letters and just say thanks? I can’t fathom it.”

“The phrase ‘circle back’ always secretly made me think of boats. You leave someone onshore, and then you circle back later to get them.” Garrett was quiet for a moment. “I like this one,” he said. “ ‘He’s a high-functioning sleepwalker, essentially.’ ”

“I remember the woman who said that.” Clark wondered what had happened to her.

He’d been spending more time in the past lately. He liked to close his eyes and let his memories overtake him. A life, remembered, is a series of photographs and disconnected short films: the school play when he was nine, his father beaming in the front row; clubbing with Arthur in Toronto, under whirling lights; a lecture hall at NYU. An executive, a client, running his hands through his hair as he talked about his terrible boss. A procession of lovers, remembered in details: a set of dark blue sheets, a perfect cup of tea, a pair of sunglasses, a smile. The Brazilian pepper tree in a friend’s backyard in Silver Lake. A bouquet of tiger lilies on a desk. Robert’s smile. His mother’s hands, knitting while she listened to the BBC.

He woke to quiet voices. This had been happening more and more lately, this nodding off unexpectedly, and it left him with an unsettled intimation of rehearsal. You fall asleep for short periods and then for longer periods and then forever. He straightened in the armchair, blinking. Garrett was gone. The last light of the day angled in through the glass and caught the chrome perfection of the motorcycle.

“Did I wake you?” Sullivan asked. He was the head of security, a man of fifty who’d walked in a decade earlier with his daughter. “I’d like to introduce you to our latest arrivals.”

“How do you do,” Clark said. The arrivals were a man and a woman, perhaps in their early thirties, the woman carrying a baby in a sling.

“I’m Charlie,” the woman said. “This is Jeremy, my husband, and little Annabel.” Tattoos covered almost every inch of her bare arms. He saw flowers, musical notes, names in an elaborate scroll, a rabbit. Four knives tattooed in a row on her right forearm. He knew what this tattoo meant, and when he looked he saw a counterpart on her husband’s skin, two small dark arrows on the back of his left wrist. She’d killed four people, then, and he’d killed two, and now they’d just dropped in with their baby, and by the absurd standards of the new world—there was a part of him that never stopped exclaiming at the absurd standards of the new world—this was all perfectly normal. The baby smiled at Clark. Clark smiled back.
