Out here, the crying was much louder.

Maureen strode purposefully across the lawn of colored lava and stepped over the border of railroad ties. This was the first time she’d actually set foot on the Thorpes’ property. It felt strange, somehow. The backyard was enclosed, but between the boards of the fence she could make out the Japanese garden Lewis had told them about. He was fascinated by Japanese culture, and had translated several of the great haiku poets; he’d mentioned some names Maureen had never heard of. What she could see of the garden looked tranquil. Serene. At dinner that night, Lewis had told a story about the Zen master who’d asked an apprentice to tidy his garden. The apprentice had spent all day at it, removing every last fallen leaf, sweeping and polishing the stone paths until they gleamed, raking the sand into regular lines. At last, the Zen master had emerged to scrutinize the work. “Perfect?” the apprentice asked as he displayed the meticulous garden. But the master shook his head. Then he gathered up a handful of pebbles and scattered them across the spotless sand. “Now it is perfect,” he replied. Maureen remembered how Lewis’s eyes had sparkled with amusement as he told the story.

She hurried forward, the crying strong in her ears.

Ahead was the Thorpes’ kitchen door. Maureen stepped up to it, carefully arranged a bright smile on her face, and pulled open the screen. She began to knock, but with the pressure of her first rap the door swung inward.

She took a step.

“Hello?” she said. “Lindsay? Lewis?”

Here, in the house, the wailing was almost physically painful. She hadn’t known an infant could cry so loud. Wherever the parents were, they certainly couldn’t hear her over the baby. How could they be ignoring it? Was it possible they were showering? Or engaged in some kinky sex act? Abruptly, she felt self-conscious, and glanced around. The kitchen was beautiful: professional-grade appliances, glossy black counters. But it was empty.

The kitchen led directly into a breakfast nook, gilded by morning light. And there was the child: up ahead, in the archway between the breakfast nook and some other space that, from what she could see, looked like a living room. The infant was strapped tightly into her high chair, facing the living room. The little face was mottled from crying, and the cheeks were stained with mucus and tears.

Maureen rushed forward. “Oh, you poor thing.” Balancing the cookies awkwardly, she fished for a tissue, cleaned the child’s face. “There, there.”

But the crying did not ease. The baby was pounding her little fists, staring fixedly ahead, inconsolable.

It took quite some time to wipe the red face clean, and by the time she was done Maureen’s ears were ringing with the noise. It wasn’t until she was pushing the tissue back into the pocket of her jeans that she thought to follow the child’s line of sight into the living room.

And when she did, the cry of the child, the crash of china as she dropped the cookies, were instantly drowned by the sound of her screams.

Christopher Lash stepped out of the cab and into the tumult of Madison Avenue. It had been half a year since he was last in New York, and those months seemed to have softened him. He hadn’t missed the acrid diesel plumes belching from serried rows of buses; he’d forgotten the unpleasantly burnt aroma of the sidewalk pretzel stands. The throngs of passersby, barking into cell phones; the blat of horns; the angry interplay of cars and trucks — it all reminded him of the frantic, senseless activity of an ant colony, exposed from beneath a rock.

Taking a firm grip on his leather satchel, he stepped onto the sidewalk and inserted himself deftly into the crowds. It had been a long time, too, since he’d carried the satchel, and it felt foreign and uncomfortable in his hand.

He crossed Fifty-seventh Street, letting himself be carried along by the river of humanity, and headed south. Another block, and the crowds eased somewhat. He crossed Fifty-sixth, then slid into an empty doorway, where he could pause a moment without being jostled. Placing his satchel carefully between his shoes, he gazed upward.

Across the street, a rectangular tower rose into the sky. There was no number, or corporate lettering, to betray what lay within. They were rendered unnecessary by the logo that — thanks to countless high-profile news reports — had recently become almost as familiar an American icon as the golden arches: the sleek, elongated infinity symbol that hovered just above the building’s entrance. The tower rose to a setback, halfway up its massive flank; higher, decorative latticework ran around the structure like a ribbon, setting off the top few floors. But this simplicity was deceptive. The tower’s skin had a richness, a sense of depth, almost like the paintwork on the most expensive of cars. Recent architectural textbooks called the building “obsidian,” but that wasn’t quite correct: it had a warm, pellucid glow that seemed almost drawn from its environment, leaving the surrounding buildings cold and colorless by comparison.

Dropping his gaze from the facade, he fished into the pocket of his suit jacket and pulled out a piece of business stationery. At the top, “Eden Incorporated” was embossed in elegant type beside the infinity logo; “deliver by courier” was stamped at the bottom. He reread the brief message below.

The letter yielded up no more information than it had the other times he’d read it, and Lash returned it to his pocket.

He waited for the light to change, then picked up his satchel and made his way across the street. The tower was set back extravagantly from the sidewalk, creating a welcoming oasis. There was a fountain here: marble satyrs and nymphs disporting themselves around a bent, ancient figure. Lash peered curiously through the curtain of mist at the figure. It seemed a strange centerpiece for a fountain: no matter how he stared, he could not quite determine whether it was male or female.

Beyond the fountain, the revolving doors were kept in constant motion. Lash stopped again, observing this traffic intently. Almost everyone was entering, not leaving. But it was almost ten-thirty, so it couldn’t be employees he was seeing. No, they must all be clients; or, more likely, would-be clients.

The lobby was large and high-ceilinged, and he paused again just inside. Although the surfaces were of pink marble, indirect lighting lent the space an unusual warmth. There was an information desk in its center, of the same obsidian as the building’s exterior. Along the right wall, beyond a security checkpoint, lay a long bank of elevators. New arrivals continued to stream by him. They were a remarkably heterogeneous crowd: all ages, races, heights, builds. They looked hopeful, eager, perhaps a little apprehensive. The excitement in the air was palpable. Some headed toward the far end of the lobby, where twin escalators climbed toward a wide, arched passage. CANDIDATE PROCESSING was engraved above the passage in discreet gold lettering. Others were moving toward a set of doors below the escalators marked APPLICATIONS. And still others had gravitated to the left side of the lobby, where Lash caught the flicker of myriad movements. Curious, he drifted closer.

Across a wide swath of the left wall, floor to ceiling, large flatscreen plasma displays had been set edge to edge in a huge matrix. On each screen was the head shot of a different person, talking to the camera: men and women, old and young. The faces were so different from each other that, for a moment, Lash sensed but could not place the commonality they shared. Then he realized: every face was smiling, almost serene.
