The call came as Inspector Mats Lundström was contemplating the profound sadness of a microwaved meatball dinner. The rain streaked his apartment window in Växjö, turning the city lights into blurry smears of gold. It was his sergeant, Anja, her voice crisp with professional excitement.
“A body, Mats. Out at Lakeholm Manor. Old money. The matriarch, Elsa Vesterberg. Looks like suicide, but the local copper on scene has a bad feeling.”
Lundström grunted, pushing his plate away. A bad feeling was the only thing that made the job interesting anymore. “I’m on my way.”
Lakeholm Manor was a hulking silhouette of dark wood and white trim, brooding over the mist-shrouded lake that gave it its name. It spoke of generations of timber wealth and quiet, unassailable power. Inside, the air was thick with the scent of old polish and newer tension.
The local officer, a fresh-faced constable, met him in the grand hall. “Inspector. She’s in the library. Took a dose of cyanide, it seems. But…” He gestured vaguely.
Elsa Vesterberg, a woman in her late seventies with a hawk-like profile even in death, was seated in a leather wingback chair. A tipped-over whiskey glass lay on the Persian rug, its contents soaking into the intricate patterns. A small, empty vial was on the desk beside an open ledger.
“Too neat,” Lundström murmured, his hands shoved deep into the pockets of his worn trench coat. He wasn’t talking to anyone in particular. He scanned the room. A fire smouldered in the grate. Books lined the walls, their leather spines a testament to unread classics. “Where’s the note?”
“No note, sir,” the constable said.
“Precisely. A woman who kept ledgers this meticulous wouldn’t leave this world without an itemised list of grievances.” He crouched, his knees complaining silently. He didn’t touch the glass, but he noted the way it had fallen. “And who found her?”
“The housekeeper, Birgit. She’s in the kitchen with the family.”
The ‘family’ was a collection of carefully composed distress in the drawing-room. There was Henrik, Elsa’s nephew, a man in his forties with the soft hands and petulant mouth of someone who managed a fortune he didn’t own. His wife, Eva, was all sharp angles and nervous energy, her fingers constantly plucking at her silk scarf. Then there was the grandson, Lukas, in his early twenties, with the sullen, artistic look of someone who considered the world a personal insult. And finally, the lawyer, Stig Molin, a man so impeccably grey he seemed to blend with the wallpaper.
Lundström let Sergeant Anja take the lead with the family while he sought out the housekeeper. Birgit was a solid, no-nonsense woman in her sixties, her eyes red-rimmed but her posture ramrod straight.
“She would never,” Birgit said, crushing a tea towel in her hands. “Not Miss Elsa. She was… formidable. And she was afraid.”
“Afraid of what?” Lundström asked, leaning against the vast Aga cooker.
“Of being got rid of. She was changing her will. Again. She told me so yesterday. She said, ‘Birgit, the vultures are circling, but I’ll clip their wings before I’m done.’ She had an appointment with Mr. Molin today to sign the new documents.”
Lundström found Stig Molin in the study, looking distinctly uncomfortable. “The new will, Mr. Molin. What were the terms?”
The lawyer sighed, a practised sound of legal regret. “I cannot divulge...”
“A woman is dead. The will is now a central piece of evidence. Divulge.”
“Very well. The old will divided the estate evenly between Henrik and Lukas, with a bequest for Eva and a pension for Birgit. The new one… cut everyone out. She was leaving the entire estate, lock, stock, and timber, to a nature conservation trust. She said her family were ‘leeches who had squandered enough.’”
Later, in the library, Lundström shared this with Anja. “Motive, suddenly, for everyone.”
“But the door was locked from the inside,” Anja countered. “The constable confirmed it. Windows, too.”
Lundström walked to the French windows, examining the latch. It was an old, brass mechanism. He ran a thumb over it, then looked out at the rain-lashed terrace. Something caught his eye: a tiny, dark smear on the white stone balustrade, almost washed away by the rain. Mud.
The following day, the forensics report landed on his desk. The whiskey in the glass and in Elsa’s system contained a lethal dose of potassium cyanide. But there were no prints on the vial except for Elsa’s, smudged as if her hand had been placed there. And then, the curious detail: under her fingernails, they found minute traces of soil and a specific, blue-tinted polyester fibre.
“Not from her own clothes, and not from anything in the library,” Anja said.
Lundström’s mind, which had been idling like a reliable old Volvo engine, suddenly kicked into gear. He thought of the locked room. The mud outside. The fibres.
He drove back to Lakeholm, ignoring the family, and went straight to the boathouse. Inside, alongside a vintage motorboat, was a rowing skiff. And tucked away in a corner, hung on a peg, was a blue, polyester work jacket, damp at the cuffs and smeared with mud. It belonged to the groundsman, a quiet, surly man named Pettersson.
Confronted in his cottage, Pettersson broke easily. “He paid me! Said it was just a prank, to scare her!”
“Who?” Lundström’s voice was dangerously quiet.
“The boy. Lukas. He gave me five thousand kronor. Said his grandmother was getting paranoid. Told me to go up to the library terrace last night, make some noise, scratch at the window. He said it would prove she was losing her mind.”
Lundström had Lukas brought in for questioning. The young man was defiant, then frightened.
“It was just a joke! I wanted her to think she was seeing things. I was trying to get Uncle Henrik named as her guardian, so he could stop her from throwing all our money away on badgers and beetles! I didn’t kill her!”
Back at the station, Lundström felt the familiar, nagging itch. The pieces were there, but the picture was wrong. Lukas’s stupid plan provided the means for the murder, the distraction at the window would have made Elsa get up from her chair, maybe call out. But it didn’t explain the poison in the glass. Or the locked door.
He sat in his office, the dim light glinting off the framed photo of his son, Tom, grinning in his Oxford gown. He missed the boy’s clear-eyed logic. He looked at the evidence board: the will, the family, the jacket, the mud.
And then he saw it. The ledger on Elsa’s desk. He’d assumed it was for accounts. But what if it was a diary? He drove back to the manor for the third time, the summer night refusing to grow fully dark.
In the library, now sealed, he put on gloves and opened the heavy ledger. It wasn’t accounts. It was a log of observations, written in a sharp, precise hand. Henrik took 5000 from the safe again. Eva’s new necklace, must be 20,000. Lukas’s idiotic ‘art’ grant, another 10,000. And the last entry, dated the day she died: Stig was here. More nervous than usual. Could he be in on it? Must finalise the new will tomorrow. Tired of their lies.
Stig was here.
The lawyer. He had access. He had a motive, if the old will stood, his firm continued to manage the vast estate. A nature trust would likely use its own lawyers. He had been in the house that evening, ‘comforting the family’.
Lundström sent Anja to check Molin’s alibi for the critical time. It was shaky. He’d claimed to be in his study in town, but a cleaner had seen his car near the manor.
The final piece clicked into place when Lundström examined the French windows again. The lock was old, the kind with a large, protruding key. He looked at the keyhole from the outside. Then he went into the garden and found what he was looking for: a long, thin, flexible stem of a hardy fern, snapped near the base.
He assembled everyone in the library, the family, the lawyer, the housekeeper. The room was thick with animosity and fear.
“Elsa Vesterberg was murdered,” Lundström began, his voice flat and tired. “It was made to look like suicide, but the killer made mistakes. He used Lukas’s childish prank as a cover. While Pettersson was scratching at the window, distracting Elsa, the killer was already in the room.”
He turned to Stig Molin. “You were here earlier, discussing the will. You knew she drank a whiskey every night at nine. You knew which glass she used. You slipped the cyanide into the decanter before you left. A gamble, but a calculated one. You then pretended to leave, but doubled back. When Pettersson caused his distraction, Elsa got up. She went to the window. And you, from the terrace, used this, ” he held up the fern stem. “...to push the key from the outside lock. It fell to the rug inside. Then you simply reached through the cat flap in the scullery door, a flap big enough for a small dog, or a man’s arm and used a length of wire with a hook to retrieve the key, lock the door from the outside, and pull the key back out, dropping it on the floor near her chair. You even guided her dead fingers onto the vial to plant her prints. You were creating a perfect, sealed room.”
Molin’s face was a mask of contempt. “This is fantasy, Inspector. Why would I do such a thing?”
“For the same reason most murders happen. Money. Or rather, the management of it. With the old will intact, your firm retains control. The new will would have ruined you. You saw the entries in her ledger. She was starting to suspect you.”
Molin laughed, a dry, brittle sound. “A plant stem? A cat flap? You have no proof.”
“We have the security camera from the neighbour’s house across the lake,” Lundström lied smoothly, the way he had learned to do over thirty years. “It’s quite a powerful lens. It clearly shows a man of your description on the terrace, performing that exact little pantomime with the fern. The forensics team are going over your car and your office as we speak. They’ll find traces of the soil from the terrace, and the unique polyester fibre from Pettersson’s jacket, which you had to brush past in the dark boathouse to get your ‘tool’.”
It was the last bluff that broke him. The mention of the blue fibre, the concrete, damning detail he hadn’t considered. Stig Molin’s shoulders slumped, the grey man finally showing his colour. “She was going to throw it all away,” he whispered.
As Anja led him away, Lundström walked out onto the terrace. The mist was clearing, and the first light of dawn was painting the lake in shades of silver and rose. It was beautiful, and it was peaceful. He thought of Tom in England, and for the first time in weeks, he didn’t feel the ache of distance, but a simple desire to call him and hear his voice. The puzzle was solved, the balance, however fragile, restored. For now, it was enough.
