The young boy was circling the convertible, eyes full of love for it, but giving Mallory a wide berth, sensing trouble if he came closer-if he should actually touch her car. Finally, he came to rest a short distance away, asking, “Are you hunting somebody on this road?”

Mallory was rarely taken by surprise, and now it must show on her face.

Encouraged by her reaction, the boy took one step closer, politely asking, “You got a picture to show us?” Failing to get an answer, he took her for a foreigner, and his hands described a square in the air, as if this might communicate a photograph.

“What?”

“A picture!” said the old man, frustrated now that the boy beside him had exhausted his vocabulary in the spoken word and sign language. He jerked one thumb back toward the field on the far side of his gas station. “All those people who camped here last night was carrying damn pictures.”

She hung the nozzle on the pump and crossed the lot to round the small building and look out over the field beyond the gas station. They must have been very neat campers. There was no debris left behind, only charred circles from campfires and the tire marks of many different vehicles. When she returned to the gas pump, the old man was still muttering.

“Like I’d remember every customer who stopped for gas in the past twenty years.” One hand rested a moment on the boy’s s houlder. “And my grandson here, damned if those fools didn’t ask him to have a look, too. Posters and pictures and itty bitty locket photos-just every damn thing.”

“But the ones I saw looked like they was just kids.” The boy shyly edged closer to Mallory. “So… if you’ve got a picture-”

“I don’t.” She had no photographs, only letters. And she did not believe that the old man would remember another V o lkswagen driver who had come this way before she was born, even though that driver had one standout feature.

Mallory listened to the old man grumble about making change for her large bill, and then she drove on down the road. In the rearview mirror, she could see the boy running after her car, waving both hands, and she heard him yell out, “I hope you find him!”

It was unnerving that this child should know her business. She brought one fist down on the dashboard with the force of a hammer.

Pain brought focus.

She glanced at the knapsack, where she had stashed the letters. They would provide her with the structure she needed to get through this day. Mallory could see no farther into the future.

More cars were trickling onto Route 80. Rush hour was dawning on the state of Indiana, and Chicago was still hours away. But Riker was in no hurry now, and he never reached for the portable siren that would scare these civilians out of his lane. He no longer needed the LoJack tracker to tell him which way Mallory was going. The world’s best technology could not predict where she would go next, but suddenly he could. He knew every route she would drive, every town she would pass through. There would be lots of catch-up time ahead, for she was traveling down a very old road, a slow road. He remembered it well.

South of Waggoner, Illinois, if not for the spotlights, she would have driven past the queen. Mallory had expected something larger, given the letter writer’s love of spectacle on the scale of fiberglass giants. This white marble statue was merely life-size and maybe smaller. She pulled off the road to park on a small patch of concrete in front of the shrine to the Virgin Mary, also known as Queen of the Road and Our Lady of the Highways. The nearby farmhouse showed no sign of life. She was no closer to understanding the point of traveling from one odd thing to another. Perhaps she had read too much importance into sightseeing. One clue was in the rule forbidding the use of cameras, lest she “-fall into the trap of looking at stale minutes of a time that passed you by. Life won’t pose for pictures.” However, Illinois was still flat, and this statue provided small relief from the landscape. Disappointed again, she returned to the car and the road.

The sun was rising at her back, and she was playing recommended music for sunrise, Brandenburg Concerto no. 3. The author of the letters had described it as “-sunlit music with acrobatic notes of many colors, airborne tunes that lift you up out of your seat.”

Failing to be uplifted, Mallory went on to the next song for a new day. She put the car in gear and sped down the road with the Rolling Stones screaming lyrics at the recommended volume of the second letter: “If it won’t deafen a cat, it’s not loud enough.”

She found the letter writer’s choice of tunes lacked any logic or style. This was not the playlist of an orderly brain that made distinctions between classical and rock, pop and jazz. The man’s disorganized mind was irritating. Yet she drove his road and played his songs.

Her car slowed down behind a long line of more law-abiding vehicles. From force of habit, she crawled up on the bumper of the last car, forgetting momentarily that Volkswagens did not inspire fear in the driving public. As the route curved and wound, she waited until the road led her into a straightaway. Switching into the lane for oncoming traffic, she traveled from lawful miles per hour to one-fifty in seconds, passing a Lincoln that trailed a Winnebago following a truck-bed camper and cars pulling small, roly-poly trailers, sedans with roof racks piled high with bedrolls and tent poles, and more cars packed up to the windows with suitcases and duffel bags. It was a caravan of travelers bound together by the close spacing of one vehicle invisibly tethered to the next.

April Waylon’s friends?

This must be the band of neat tourists who had camped last night in the field by the gas station, leaving nothing behind but their ashes and impressions of tire treads.

A moment later, the caravan disappeared from Mallory’s rearview mirror. She was intoxicated with speed, flying across an open road. Car and woman had merged. Her heartbeat was in sync with the racing performance of a perfect engine, for she had become a new kind of creature, one who had legs that rolled with smooth grace in the weave of changing lanes and taking curves. Half an hour down the road, when at last she thought of food, she thought of it as fuel and pulled into the parking lot of a diner.

The countryside around this southwest area of Illinois was blighted and parched. The trees around the lot were specked with dead leaves that had died in their buds, and the grass of a neighboring field had turned brown. The only other car in the parking lot was an old green Ford sedan that carried out-of-state plates and streaks left by rainwater cutting through road dust, and the back end was attracting flies.

Lots of them.

The black insects buzzed and clustered along the edges of the closed trunk, mad for a way to get inside. She looked up to scan the wide windows that lined the diner. The only occupant was a stout young woman wearing a white uniform and running a rag across a Formica countertop. The waitress went on to polish the fixtures of the coffee machines and even the metal brackets for glass shelves holding muffins and pies. Mallory approved of all things neat and clean, and now she knew that the waitress’s car was the old Volvo parked on the dead grass off to one side of the diner. That car had been recently washed, and a pine-tree air freshener hung from the rearview mirror above the plastic Jesus on the dashboard. Mallory guessed that the woman parked outside the spacious lot because she took great pride in her old Volvo; she would not care to see it dented by some drunken driver seeking sobriety in a pot of her coffee.

Swatting at flies, Mallory turned back to the dirty green Ford. It had one new tire, probably the spare. She bent down to look through the driver’s-side window. Old regimens died hard, though it had been months since she had last plied her trade as a homicide detective. There was an auto-club card on the console, and a cell phone was plugged into the ignition charger. A flashlight lay on the floor mat, its lens and bulb broken. So the driver’s c e ll phone was not working. He had stopped to change his own tire-and then something else had gone wrong.
