5. The Pure Corrosion

The trial of Dr. Lemuel Frye began on the third Monday of November, in the Wesson County courthouse, a limestone building with a cracked cornerstone and a courtroom that smelled of floor wax and stale tobacco. The gallery was packed with railroad men in their Sunday suits and their wives in dark dresses, the same wives who had served lemonade at the company picnic where Celia Drewe had laughed and Harlan Voss had touched her arm and Evelyn Voss had begun to plan a murder. They sat in rows like crows on a telephone wire, their eyes bright with the hunger for scandal, and they watched the defendant shuffle to his chair in a borrowed suit that was too big at the shoulders.

Evelyn sat in the third row, between Harlan and the fireman Tully. She wore a black dress with a white collar, the picture of a grieving friend, and she kept her hands folded in her lap and her eyes fixed on the judge. She had spent the three weeks since Celia's death preparing for this moment, rehearsing her testimony, anticipating every question the prosecutor might ask. The jealousy was a low flame now, banked and controlled, but it still burned. It would always burn.

The prosecutor was a man named Roland Tate, a county attorney with political ambitions and a face that looked like it had been carved from the same limestone as the courthouse. He called his witnesses one by one: the deputy who had found the bottle in Frye's crawlspace, the inventory clerk who had documented the missing arsenic from the signal shed, the night nurse who had seen Frye at Celia's bedside on the evening she collapsed. Each testimony was a brick in the wall he was building, and the wall was solid and square and left no room for doubt.

Then he called Evelyn Voss.

She walked to the witness stand with her head held high and her hand on the Bible and her voice steady as she swore to tell the truth. Tate approached her gently, the way a good prosecutor approaches a sympathetic witness, and he asked her about the nerve tonic, about the Tuesday visits, about the friendship she had offered to a lonely widow in a strange town.

"I only wanted to help her," Evelyn said, and her voice caught, just slightly, in the exact right place. "She was so alone. Her husband had been killed in the Birmingham yard. She didn't know anyone in Mercer's Bend. I thought if I could just be a friend to her, if I could just make her feel welcome..."

"And did you ever suspect that Dr. Frye was harming her?"

"Not at first. I didn't want to believe it. He was a doctor. A company physician. But then she started getting sicker, and I noticed that it was always worse on Wednesdays, the day after his visits. And she told me things. Things about his examinations. Things that made me uncomfortable." Evelyn looked down at her hands. "I should have said something sooner. I should have protected her. But I was afraid. I was afraid of what he might do."

A murmur ran through the gallery. Tate nodded gravely and turned the witness over to the defense.

The defense attorney was a man named Silas Crane, a rail-thin lawyer from Mobile with a reputation for vicious cross-examinations and a voice that cut through the courtroom like a switch engine whistle. He approached the witness stand with his hands clasped behind his back and his head tilted at an angle that made him look like a bird examining a worm.

"Mrs. Voss," he said, "you testified that you prepared a nerve tonic for the deceased. Is that correct?"

"Yes. An old family recipe. Angelica root and chamomile and honey."

"And you delivered this tonic every Tuesday?"

"Every Tuesday, yes."

"For how many weeks?"

Evelyn paused. She had anticipated this question. "Six weeks. Maybe seven. I didn't keep count."

"Six or seven weeks. And during that entire time, you never noticed anything wrong with the tonic? Any strange taste, any unusual color?"

"No. It was just tea. My mother made it for years. It never hurt anyone."

Crane stopped pacing and turned to face her directly. "Mrs. Voss, are you aware that the arsenic found in Mrs. Drewe's body was potassium arsenite, the same chemical stored in the railroad's maintenance shed?"

"I've read the newspapers, Mr. Crane. I'm aware of what the police found."

"And are you aware that your husband, Conductor Harlan Voss, had a key to that maintenance shed?"

The gallery went silent. Evelyn felt the jealousy flare, hot and sudden. Harlan. Crane was bringing Harlan into it. She had not anticipated that.

"My husband has keys to many parts of the yard. He's a conductor. It's his job."

"Indeed. And did your husband ever bring home any chemicals from the yard? Any weed killer, any rat poison, anything of that nature?"

"No. Never."

"So you're asking this jury to believe that Dr. Frye, a company physician with no access to the maintenance shed, somehow obtained arsenic from a locked chemical cabinet, while your husband, who had a key and daily access, never brought any chemicals home?"

Evelyn's hands tightened in her lap, but her voice remained steady. "Dr. Frye had access to the dispensary. The police found an empty bottle of potassium arsenite hidden in his office. The same chemical. The same label. He had the means and the opportunity."

"He had the means and the opportunity," Crane repeated. "And what about motive, Mrs. Voss? The prosecution has suggested that Dr. Frye poisoned Mrs. Drewe because she rejected his advances. But you were her closest friend. You saw her every Tuesday. You prepared the tonic she drank. If anyone had the opportunity to poison her, Mrs. Voss, it was you."

Tate was on his feet, objecting, but Crane waved him off. "Withdrawn, Your Honor. I have no further questions."

Evelyn stepped down from the witness stand and walked back to her seat. Her legs were steady. Her face was calm. But inside her chest, the jealousy was roaring. Crane had done something dangerous. He had planted a seed. He had put Harlan's name into the record, had suggested an alternative theory of the crime. If the jury began to doubt Frye's guilt, they might start looking elsewhere. They might start looking at her.

That night, in the kitchen of the conductor's house, Evelyn confronted her husband.

"Crane asked about your key," she said. "He asked if you ever brought chemicals home from the yard. Why would he ask that, Harlan? What did you tell them?"

Harlan was sitting at the table, his coupling pin lying before him like a talisman. His face was gray and drawn, and he would not meet her eyes. "I told them the truth. Carmody asked me about the key weeks ago. I told him I had access to the maintenance shed. I didn't think it mattered."

"You didn't think it mattered." Evelyn's voice was flat, cold. "They're trying to hang this on someone, Harlan. If they can't hang it on Frye, they'll hang it on you. Or me. And you handed them the rope."

"It's not like that. Carmody said I wasn't a suspect. He said he just needed to understand who had access."

"Carmody lies. All investigators lie. It's what they do." Evelyn turned away from him and stared out the kitchen window. The switch engine was idling in the yard, its headlamp a single yellow eye in the darkness. "You need to do something for me. You need to go to the union. Get a lawyer. Get ahead of this before Crane puts you on the stand."

"A lawyer? Evie, I haven't done anything wrong."

"You have a key. You have access. You're married to the woman who made the tonic. If the defense starts looking for an alternative suspect, you're the easiest target in Mercer's Bend. Unless Frye confesses, this isn't over. And Frye isn't going to confess. He's going to sit in that chair and let Crane point the finger at you." She turned back to him, and her voice softened. "Please, Harlan. For me. For us. Talk to the union."

Harlan looked at her for a long moment. Then he nodded, slowly, the way a man nods when he knows he's in over his head. "All right. I'll talk to them tomorrow."

He went to bed early, exhausted from the trial and the yard and the weight of everything he did not understand. Evelyn stayed in the kitchen, drinking coffee and staring at the coupling pin he had left on the table. It was a heavy thing, solid iron, polished smooth by years of use. She picked it up and turned it over in her hands. It was the symbol of his profession, the tool of his trade, the object he loved more than he had ever loved her. And it would be the thing that destroyed him.

The trial lasted four more days. The prosecution brought in the toxicology reports from the Meridianville hospital, the inventory records from the signal shed, the testimony of the locksmith who had confirmed that the maintenance shed lock had been forced. The defense brought in character witnesses for Frye—patients who swore he was a gentle and compassionate doctor, nurses who said he had never been anything but professional. Crane hammered at the lack of direct evidence, the circumstantial nature of the case, the possibility that someone else had accessed the chemicals and framed his client.

But the bottle in the crawlspace was too damning. The forged letters were too suspicious. The jury deliberated for six hours and returned with a verdict of guilty.

Dr. Lemuel Frye was sentenced to life in prison, to be served at the state penitentiary in Holman. He wept when the verdict was read, his shoulders shaking, his wet eyes streaming. The railroad wives in the gallery nodded their heads in grim satisfaction. Justice had been done. The poisoner was going to prison. The town could go back to its normal rhythms, the switch engine bell and the coupling pins and the slow, steady decay of a place the world had forgotten.

But Jack Carmody was not satisfied.

He came to the conductor's house on the evening after the verdict, his overcoat buttoned against the November cold, his face unreadable. Evelyn answered the door with a dish towel in her hands and an expression of mild surprise on her face.

"Mr. Carmody. I thought the case was closed."

"The case against Frye is closed. The case against the person who actually poisoned Celia Drewe is still open." He stepped inside without being invited and stood in the center of the parlor, the same parlor where he had stood with the warrant weeks ago. "I've been going back over the evidence. The timeline. The Tuesday visits. The way the symptoms always got worse on Wednesdays. Frye visited on Tuesdays, yes—but only in the afternoon. He wasn't there in the morning. He wasn't there when Mrs. Drewe drank her morning tea. The tea she said tasted metallic. The tea you prepared."

"The jury didn't think so."

"The jury didn't hear everything. They didn't hear about the chemistry books in your attic, the ones with the chapters on arsenic bookmarked. They didn't hear about the conversation you had with Mrs. Drewe on the day she died—the one the night nurse overheard, the one where Mrs. Drewe asked you if you had poisoned her. The nurse was in the hallway. She heard everything."

Evelyn's hands tightened on the dish towel. The night nurse. She had been so careful. She had waited until the nurse was at lunch. But the nurse had come back early. The nurse had been in the hallway. The nurse had heard.

"The nurse didn't testify," she said. "She wasn't called."

"No. Tate didn't want to muddy his case. A dying woman's accusation, no corroboration, no physical evidence. It wouldn't have held up in court. But it holds up for me." Carmody stepped closer, and his voice dropped. "I know what you are, Mrs. Voss. I've known for weeks. You're a woman who decided to kill another woman because your husband looked at her too long at a picnic. You're a woman who spent six weeks poisoning a widow with your mother's nerve tonic recipe, smiling at her every Tuesday, holding her hand while the arsenic ate her from the inside. And then, when she figured it out, you went to the clinic and finished her with an overdose of phenobarbital while she lay in a hospital bed."

"You can't prove any of that."

"No. I can't. Frye destroyed the evidence when he hid that bottle, and you made sure there was nothing left to find. You're going to walk away from this. You're going to stay married to Harlan and go to church on Sundays and bake your pies for the company picnic. And no one is ever going to know what you did." Carmody put on his hat. "But I know. And you know. And every time you look in the mirror for the rest of your life, you're going to see a murderer."

He walked out the door and disappeared into the November darkness. Evelyn stood in the parlor, the dish towel still clutched in her hands, and listened to the switch engine bell toll the hour. Carmody knew. The night nurse knew. The truth was out there, fragmentary and unprovable, but out there nonetheless. She would have to live with it. She would have to carry it inside her, the way she had carried the jealousy, the way she had carried the arsenic bottle in her handbag every Tuesday for six weeks.

But she had carried heavier things. She had carried fifteen years of marriage to a man who did not see her. She had carried the miscarriages and the disappointments and the slow, grinding erasure of everything she had wanted to be. She could carry this too.

She went to the kitchen and poured herself a cup of coffee. The house was quiet. Harlan was at the yard, working the night shift. The trial was over. The doctor was in prison. The widow was dead. And Evelyn Voss was still standing, still composed, still the perfect wife in the conductor's house on the clean street.

But the jealousy was not gone. It had only changed shape. It had turned its cold gaze from Celia Drewe to Jack Carmody, to the night nurse, to everyone who knew the truth and might one day speak it. She would have to be careful. She would have to be patient. She would have to wait for the right moment, the way she had waited for the right moment to begin poisoning Celia.

And in the closet, behind the wedding veil, a new bottle was waiting. Not arsenic this time. Something subtler. Something that mimicked heart failure in a man who had spent thirty years working the railroad, whose heart was already weak from the stress and the irregular hours and the constant, grinding weight of a life he had never chosen.

Harlan Voss had betrayed her. He had told Carmody about the chemistry books. He had given Carmody the key to the maintenance shed. He had sat in the courtroom and watched his wife be accused of murder and done nothing, said nothing, been nothing but the simple, incurious man he had always been.

He would come home from the yard at six o'clock tomorrow morning, tired and hungry and expecting his breakfast. And Evelyn would be there, as she always was, with the coffee hot and the eggs fried and the table set with the same care she had shown for fifteen years. And in his coffee, dissolved so completely that he would taste nothing but the bitterness of the beans, would be the first dose of a new poison.

The switch engine bell rang midnight. Outside, the first snow of winter was beginning to fall, dusting the cinders with white. In the state penitentiary at Holman, Dr. Lemuel Frye was lying on a cot in a cell, staring at the ceiling, trying to understand how his life had come apart. In the county cemetery, Celia Drewe was lying under a headstone that read "Beloved Wife, Taken Too Soon." And in the conductor's house on the clean street, Evelyn Voss was standing at the kitchen window, watching the snow fall, her face as calm and cold and patient as the poison she had learned to wield.

The jealousy was still there. It would always be there. It was the one thing that would never leave her. The one companion that had never failed her. The one love that had never looked away.

She finished her coffee and went to bed. Tomorrow would bring what it brought. And whatever it brought, she would be ready.

But in the darkness of the bedroom, as she lay beside Harlan's empty side of the bed, something unexpected happened. The telephone rang.

It was two o'clock in the morning. The telephone never rang at two o'clock in the morning. Evelyn picked up the receiver and heard a voice she recognized—Tully, the fireman, his words tumbling over each other in a rush of panic.

"Mrs. Voss, you need to come to the yard. There's been an accident. It's Harlan. He was coupling cars on the interchange track and the pin slipped and he went under the wheels. They've taken him to the clinic. I think—Mrs. Voss, I think he's gone."

Evelyn stood in the dark hallway, the receiver pressed to her ear, and listened to Tully's voice telling her that her husband was dead. The coupling pin had slipped. The wheels had taken him. The thing he had loved most in the world had killed him.

She hung up the telephone and stood very still. The jealousy stirred, confused, uncertain. It had been preparing for a long campaign, a slow and patient poisoning, and now the object of its hunger had been taken away. Harlan was dead. The railroad had killed him. The thing he had served for thirty years had reached up and pulled him under.

And Evelyn Voss was free. Free of the marriage. Free of the betrayal. Free of the man who had looked at Celia Drewe with hunger and at his wife with indifference. The railroad had done her work for her, and the jealousy had been cheated of its prize.

But as she stood in the dark hallway, a slow smile spread across her face. It was not a smile of grief. It was a smile of understanding. Because the jealousy was not cheated. It was still hungry. It was already turning its attention to new targets—to Jack Carmody, who knew the truth, and to the night nurse, who had heard the dying words, and to anyone who might threaten the perfect life she had built.

The switch engine bell rang the hour. The snow continued to fall. And Evelyn Voss put on her coat and walked out into the winter darkness, heading for the clinic where her husband's body lay, already composing the face she would show the world. The grieving widow. The devoted wife. The woman who had lost everything and would bear it with the same quiet grace she had borne everything else.

Behind her, in the closet, the new bottle sat waiting. And in her chest, the jealousy burned on, patient and eternal, the purest corrosion, the one fire that could never be extinguished.
