The Nearest

Kate was dragged out of sleep by her phone buzzing, with a tone indicating the kind of alert that wouldn’t leave her in peace until she responded with a suitably lucid acknowledgment. She picked the thing up off the table by the bed and peered at the screen.

“Copy that,” she intoned hoarsely. “I’ll be there in twenty minutes.”

“What is it?” Reza asked. He sounded more awake than she was.

“They found the car.”

When Kate arrived at the riverbank, the tow truck was still getting into position. Natalie’s station wagon had veered off this quiet road at a point where there were no real barriers between asphalt and water. It had left a trail of minor damage in the grass and reeds; to any passing motorist who’d given it a second thought, it probably looked no more suspicious than someone having tried to use the grass to make a U-turn. But tonight, an ER nurse on her way home from her shift had seen moonlight glinting off the metal bobbing in the reeds, and slowed down to take a closer look.

The water where the car had ended up wasn’t deep; the two traffic cops who’d come to investigate had reached it in waders. Kate was still waiting for Roma Street to authorize divers, but she doubted they’d find anything. If Natalie had been able to get out of the submerged car at all, she would not have required any superhuman abilities to make it back to the riverbank. This looked more like an attempt to hide the vehicle than an attempt at suicide. If she’d been overcome by remorse, she would have driven off a bridge.

Kate stood and waited while the traffic cops and the tow truck operator hooked up the winch and dragged the station wagon out of the water and up onto the back of the truck. Then the truck got bogged in the mud, so they had to put boards under the wheels to free it. By the time the truck was able to maneuver itself back onto solid ground, Kate had lost patience. She put on a pair of gloves and climbed up beside the station wagon, flashlight in hand.

All the doors were closed, and all the windows open; Natalie might well have been able to squeeze through a window, conscious and unharmed, but it seemed unlikely that her body had just floated out. The interior was full of silty water and vegetation, and anything not fixed that had been on the seats or the dashboard would either be buried in that muck or left behind in the river. Kate reached in and opened the glove box, which discharged a stream of water carrying a pair of plastic sunglasses and a chapstick. She groped below the dashboard for the manual release for the hood, fought with it against the sludge and grit that was blocking the mechanism, then finally heard a satisfying click.

When she walked around to the front of the car and peered in, she saw the black box, still intact. The data recorders were meant to be robust enough to survive battery fires, so a few days of immersion would be nothing. She turned and called out to the traffic cops, “Have you got an interface cable?”

“We should wait until we get to the compound, Sarge,” the older of the two replied.

“Do you have the cable or not?”

He stared back at her for a moment, then walked over to his car. Kate jumped down and went to fetch her notepad.

The data only took a few seconds to transfer, but it was encrypted; Kate sat in her car and fought her way through the process of persuading the manufacturer to send her the key. A magistrate had authorized the decryption on the day the car went missing, and she had a digital certificate attesting to that fact, but it still took three attempts to convince the Toyota website that she wasn’t a bot or a hacker.

She started with the plunge into the river. Natalie had shut off the driver supervision features ten minutes before, and while the car’s software fell somewhat short of psychiatric qualifications, up to that point it had not assessed her as being affected by any drug or medical condition: She had not been swerving erratically, or shouting obscenities, or nodding off behind the wheel. The manual override had amounted to telling the car not to trust any of its own systems from then on, so while the black box had dutifully logged her GPS coordinates as she steered off the road, the car itself had become agnostic about the wisdom of this behavior. For all it knew, the driver might have had an honest reason to believe that the car’s sensors were broken and it was liable to kill someone if it didn’t butt out and let a human take over completely.

But the GPS trace was enough to show that Natalie hadn’t been driving terribly fast at any point. She’d sped up enough to ensure that her momentum would take her over the riverbank and into the water, but she hadn’t slammed her foot down and accelerated wildly, rushing toward oblivion. When the car came to a stop in the water, it hadn’t even triggered the airbags.

Kate went back to the morning of the killings and followed the car away from the scene. At first, Natalie seemed to be heading straight for her mother’s house, but when she came within a few blocks of it, she changed her mind. She’d turned around and started driving toward her friend Mina’s apartment, only to back out again. Then her brother’s house. Then two other friends. She’d had no phone with her, and all of these people had claimed that they’d heard nothing from Natalie on that day, or since. But apparently, every time she’d made a plan to seek help, she’d given up on the idea without waiting to be rebuffed.

Kate could understand a woman who’d killed her family in a psychotic fugue snapping out of it and turning in desperation to her mother, only to decide at the last minute that she had no hope of being treated with anything but revulsion. But why would she then imagine that a whole succession of other people might be more forgiving, only to abandon that hope each time it was about to be tested?

After all the aborted journeys toward familiar faces, Natalie had driven to a shopping mall, far from her own home, and the car had remained parked there for almost three hours. That seemed like a long time to spend gathering provisions for a dash out of town—which she’d turned out to have no intention of doing, unless she’d somehow procured access to another vehicle. She’d taken her bank cards when she fled from the house, but hadn’t used them anywhere; whatever she’d bought in the mall, she must have paid for it with the remnants of her last cash withdrawal of three hundred dollars, from a few days before.

When she left the mall, she’d driven around the city in a wide arc until evening, as if she were simply killing time. She’d stopped at a fast food strip around nine o’clock, and then headed for the river to ditch the car.

Kate heard birdsong and looked away from her notepad; it was almost dawn. She checked the status of her request for divers; it had been flagged as “on hold” until a forensics team had examined the car itself.

She sent Reza a message to tell him she wouldn’t be home, then drove off in search of a diner where she could grab breakfast and use the restroom. In the mirror, she looked puffy-eyed and disheveled; she took off her shirt and washed under her arms. Natalie must have been in a much worse state when she waded out of the river, but maybe she’d been carrying a change of clothes in a plastic bag. After six days, three with rain, it was too late to send in dogs to try to pick up her scent from the riverbank.

Kate sat in a booth in the diner drinking coffee until it was almost seven o’clock, then she drove to the shopping mall where Natalie had parked for three hours. The security cameras covered the whole parking lot, and it wasn’t hard to find the moment in the recordings when Natalie drove in, but when she left the car, carrying two large, empty shopping bags, she walked away, out onto the street. Kate went through all the footage of the pedestrian entrances, but Natalie hadn’t doubled back. Whatever she’d bought in that time, she’d bought somewhere else. There were hundreds of small, freestanding shops within an hour’s walk of the mall.

Kate returned to the parking lot footage, at the time she knew the car had departed. Natalie appeared, with the shopping bags bulging, but it was impossible to see what they contained. New clothes? Hair dye? Scissors? It wouldn’t take much for her to render herself unrecognizable to anyone but her closest friends. A clear enough shot by a public CCTV camera might still trigger a face-matching algorithm, but she’d have to be much stupider than she’d proved to be so far to offer herself up to that kind of scrutiny.

The mall security guard had been watching over Kate’s shoulder. “That’s the woman who killed her own kids?” he asked. Natalie’s face was all over the media as a missing person, but the official line was still far from naming her as a suspect.

“Maybe.” Kate turned to him with a warning glance; she really didn’t want to hear anyone’s opinion on what fate Natalie deserved.

“Good luck,” he said.

She left the mall and walked out onto the street. “Mark every retailer in a six-kilometer radius,” she told her notepad, “and give me a path that visits them all.”
