About this book

Summary

A city of 75,000 that appears on no map hides a secret that could end the war—or ignite the next one. Verna Bledsoe, a sharp-eyed former fraud examiner, arrives at Oak Ridge, Tennessee, in 1944 with orders to find a spy leaking uranium enrichment data. But when her prime suspect turns up drowned before she can make contact, Verna discovers the conspiracy runs far deeper than a single traitor. To protect her friends, expose the truth, and survive, she'll have to outthink enemies hiding behind the same uniforms she serves.

Chapter 1

Chapter 1: The City That Wasn't There

The bus smelled of sweat, diesel, and the particular anxiety of people who had signed papers they weren't allowed to read.

Verna Bledsoe sat three rows from the back with her suitcase wedged between her knees and her purse clutched against her ribs, watching the Tennessee hills scroll past windows streaked with red mud. The woman beside her, a plump blonde from somewhere in Alabama judging by the accent, had spent the last forty minutes trying to make conversation. Verna had given her just enough—yes, from Knoxville, yes, clerical work, no, no husband, he's overseas—to seem friendly without being memorable.

It was a skill she'd learned at Southeastern Mutual, where being memorable meant the man whose false disability claim you were investigating might recognize you at the grocer's.

The bus turned off the highway onto a road that hadn't existed six months ago. Verna could tell because the asphalt was still black and the trees on either side had been cut so recently their stumps wept sap. A quarter mile in, the road widened, and there it was.

A gate.

Not a garden gate or a farm gate. A military gate with a guardhouse, a wooden barrier arm, and two soldiers carrying rifles that looked like they meant it. Beyond the gate, a fence of barbed wire stretched in both directions until the hills swallowed it.

"Lord," the Alabama woman said. "What'd we sign up for?"

Verna didn't answer. She was counting things. Two guard towers visible. Three telephone lines running from the guardhouse. A second fence, inner, about thirty yards behind the first. Dogs—she could hear dogs somewhere.

The bus stopped. A corporal climbed aboard with a clipboard and a face that suggested he had done this six hundred times and would do it six hundred more before anything surprised him.

"Ladies, welcome to the Clinton Engineer Works. You will present your identification and assignment letters. You will not leave the bus until directed. You will proceed to the processing center for badge photographs. You will not discuss your work, your location, or the nature of this facility with anyone outside the reservation. Is that understood?"

Nobody said yes. Nobody said no. The corporal didn't seem to need either.

Verna handed over her papers when her turn came. The name on them was real. The job description—personnel clerk, Y-12 plant—was real enough. The part that wasn't written down was the part that mattered.

Three weeks ago, in a borrowed office above a hardware store on Gay Street in Knoxville, a man named Captain Mark Henshaw had laid a photograph on the desk between them.

"Carl Denny," Henshaw had said. "Shift supervisor, Y-12 electromagnetic separation plant. We believe he's passing process data to a foreign intelligence service."

Verna had studied the photograph. Denny was about forty, heavy-jawed, with the kind of face that looked honest in the way a locked door looks honest—you trusted it until you checked the hinges.

"Why me?" she'd asked.

"Because G-2 has soldiers inside the plant and they can't get close enough. The leak is coming from the social layer—dormitories, cafeterias, dances, the places where people talk after shift. We need someone who belongs in those spaces."

"A woman."

"A specific woman. You spent three years catching men who lied for a living. Your supervisor at Southeastern Mutual said you found a two-hundred-thousand-dollar arson ring by noticing that a man's lunch receipts were from the wrong town on the wrong day."

"My supervisor talks too much."

Henshaw hadn't smiled. He was the kind of man who kept smiles in a locked drawer for special occasions. About thirty, lean, with dark hair cut military-short and gray eyes that watched everything with the patient attention of someone reading a contract he intended to enforce.

"Miss Bledsoe, I'm not going to dress this up. The work is dangerous. The facility is classified at the highest level. You'll be alone inside with no badge, no rank, and no protection except your cover. If you're exposed, we can't acknowledge you."

"That's a fine recruiting speech, Captain."

"It's the truth. I find it saves time."

She'd taken the job. Not for patriotism, though she had enough of that. Not for money, though the pay was better than insurance. She'd taken it because she was twenty-four years old, her brother was flying B-17s over Germany, her mother was rolling bandages at the Red Cross, and sitting behind a desk in Knoxville calculating the actuarial probability of barn fires felt like watching the war through a window.

Now the window was gone, and she was inside something she didn't have a name for yet.

The bus rolled through the gate.

Oak Ridge opened before her like a city someone had built in a fever dream. Wooden buildings, hundreds of them, stretched across a valley that should have held nothing but farms and timber. Dormitories in long rows. A cafeteria the size of an aircraft hangar. A recreation hall with a hand-painted sign reading HAPPY VALLEY. Streets—if you could call them streets—of churned red mud that looked like the earth itself was bleeding.

And people. Thousands of people, walking, driving, riding buses, carrying lunch pails and clipboards and the particular expression of humans who know they are doing something important but are forbidden to say what.

The Alabama woman pressed her face to the glass. "It's a whole town."

It was. A town with no name on any map, no listing in any directory, no mention in any newspaper. Seventy-five thousand people living inside a fence, building something so secret that the workers themselves didn't know what it was.

Verna knew one thing more than most of them. She knew it was a weapon.

She didn't know what kind.

The processing center was a wooden building that smelled of fresh lumber and mimeograph ink. Verna stood in line with sixty other women, had her photograph taken by a bored private, received a badge with her name and a letter-number code she didn't understand, and was directed to Dormitory W-9.

The dormitory was a long, low building divided into rooms that each held four women, two bunk beds, four lockers, and one window. The window looked out on a mud street, another dormitory, and beyond that, the hills—green and ancient and utterly indifferent to the city that had been dropped into their lap.

Verna's roommates were already there.

The first one she met was Pauline Baxter, who went by Pol and who announced herself by nearly knocking Verna over with a hug.

"You're the fourth! Thank the Lord, we've been three for two weeks and it's been like a table with a missing leg. I'm Pol. That's my bunk, top left, don't touch my radio, and if you snore I'll forgive you but I'll mention it."

Pol was twenty-two, from a mill town outside Macon, Georgia, with red-brown hair pinned in victory rolls and a smile that arrived before the rest of her face was ready. She worked as a calutron operator at Y-12, which she described as "sitting in front of a machine the size of a house and turning dials until the needles do what they're supposed to."

"What does the machine do?" Verna asked, testing.

Pol shrugged with the practiced ease of someone who'd been asked before. "Honey, I have no earthly idea. They told me to keep the needles between the lines, and I keep the needles between the lines. The PhDs come by and look at my readings and nod like I've done something clever, and I smile and pretend I know why."

The second roommate was Ida Mae Pritchard, who was sitting on the lower right bunk with a book of mathematical tables open on her knees and a pencil behind her ear. She was twenty-six, thin, with dark hair pulled back in a practical bun and eyes that looked like they'd been recently emptied of something.

"Ida Mae's our brain," Pol said. "She does statistics for the lab. Numbers and more numbers. She could tell you how many beans are in a jar just by looking at it."

"I could tell you the probable range," Ida Mae said quietly. "Not the exact number."

"See? Even her corrections are smart."

Ida Mae offered a small, careful smile. "Welcome. The hot water runs out by six-fifteen, so set your alarm."

The third roommate arrived twenty minutes later, carrying a stack of files and wearing a lab coat over her dress. Grace Okamura was twenty-three, Japanese-American, with sharp features and sharper eyes and the kind of posture that suggested she was always ready to be told she didn't belong.

"New girl?" Grace said, setting her files on her bunk.

"Verna Bledsoe. Personnel clerk."

Grace studied her for a moment longer than was comfortable. "Personnel. So you'll be the one losing our time cards."

"I'll do my best."

Something shifted in Grace's expression—not warmth, exactly, but the recognition of someone who understood dry humor as a survival mechanism. "Good. The last clerk filed me under O for Oriental. I had to explain that Okamura starts with the same letter but for different reasons."

Pol laughed. Ida Mae looked up from her numbers with something that might have been the ghost of amusement.

Verna set her suitcase on the empty bunk and began to unpack.

She had three dresses, two pairs of shoes, a coat, toiletries, a photograph of her brother in his flight jacket, and a pocket notebook with a leather cover that she'd carried through three years of insurance investigations. The notebook was blank. She intended to fill it.

That night, lying in the dark while Pol's radio played Glenn Miller softly enough to be a lullaby and Ida Mae's breathing settled into the rhythm of someone who only slept when exhaustion won the argument, Verna stared at the ceiling and did what she always did.

She made a list.

Carl Denny. Shift supervisor. Suspected of leaking process data.

Step one: make contact. Observe his habits, his associations, his spending.

Step two: identify his handler or his courier.

Step three: document the pipeline.

Step four: close it.

Ninety days. Maybe less.

She closed her eyes.

Somewhere outside, a dog barked at the fence line, and the hills held their silence like a secret they'd been keeping long before the city arrived.
