The first victim was not a person, but a swan. It floated, porcelain-white and eerily serene, on the glassy surface of Lake Helgasjön at dawn. Inspector Mats Lundström, walking his aging terrier, Nisse, along the familiar path, spotted it. He knelt, the damp morning grass soaking into the trousers of his worn suit, and saw the unnatural stillness, the unseeing black bead of an eye. He fished it out with a fallen branch. No visible injury. Its neck, a perfect question mark against the grey mist, posed the first one. By midday, the question would become a scream.

The call came as Lundström was stirring a third teaspoon of sugar into his station coffee, a futile attempt to replicate the sweetness of a life that had long since departed, first with his ex-wife, Lena, to Stockholm, and then with his son, Jens, to a university in Exeter. It was a Tuesday. Växjö was wearing its pale, late-spring green.
“Mats, it’s the hospital,” said Sergeant Erika Ljung, her usual briskness edged with something sharper. “Two families. Violent illness. They’re saying it’s the kanelbullar from the Stortorget market.”
Lundström’s large, weathered hand paused mid-stir. A public market. A staple treat. His mind, a machine honed by thirty years in the Småland police, switched from idle melancholy to a low, humming gear. Poison. It was a word that carried a medieval dread.
At the hospital, the smell of antiseptic fought a losing battle. In a curtained bay, the Pettersson family, parents and two teenage girls, lay ghastly pale, connected to drips. The mother, trembling, clutched Lundström’s sleeve. “The cinnamon… it tasted… bitter,” she whispered. “Metallic.”
Across the corridor, the same story from the Lindbergs. Both families had bought the pastries from the same stall: “Britt’s Baked Bliss,” run by Britt-Inger Karlsson, a pillar of the local Women’s Institute.
Britt-Inger, a woman whose face was as kind and round as her own buns, was in tears at the market stall, now cordoned off with fluttering police tape. “I don’t understand! I bake everything fresh! The flour, the butter, the cinnamon… all from the co-op!”
Lundström, his grey eyes missing nothing, picked up a discarded bun from the grass where a panicked customer had flung it. He brought it to his nose. Beneath the warm scent of cardamom and sugar, a faint, acrid note. “We need the co-op’s delivery lists,” he said to Erika. “And I want to speak to everyone who works with Britt-Inger. Past and present.”
* * * * * * * * * * *
The co-operative warehouse was a cathedral of mundane abundance: sacks of flour like giant white pillows, drums of syrup, industrial-sized jars of spices. The manager, sweating nervously, confirmed the deliveries to Britt-Inger were identical to those of a dozen other bakers and cafes across Växjö.
“But someone,” Lundström mused, standing before a pallet of cinnamon jars, “could add a little something extra after delivery. To one specific jar.”
Erika’s phone buzzed. Her face tightened. “Another incident. The fika at the senior centre in Teleborg. Three people taken ill. Similar symptoms.”
“What was served?”
“Apple cake. With… cinnamon.”
Lundström felt a cold knot form in his stomach. This was no accident. This was targeted, yet sprawling. A shadow was moving through the town’s larders.
The investigation room at the station became a map of malice. Photographs of victims, delivery routes, and a growing list of contaminated products, cinnamon buns, apple cake, a batch of gingerbread cookies from a different bakery, pinned to a board. The common thread was ground cinnamon, but the source seemed deliberately chaotic, designed to spread panic.
“It’s not about killing,” Lundström said, more to himself than to the team. “Not yet, anyway. The doses are sub-lethal. It’s about terror. It’s about spoiling something good.”
“A grudge?” Erika offered.
“A very specific one. Against bakers? Against cinnamon? Against the very idea of fika?” He sighed, the weight of it settling on his broad shoulders. He missed Jens with a sudden, physical ache. Missed the simplicity of a case involving a drunk and a misplaced fist.

The break came from an unexpected source: Britt-Inger’s former delivery driver, a young man named Felix. Under the gentle but relentless pressure of Lundström’s questioning, conducted over surprisingly good station coffee, Felix remembered something.
“There was a guy. Maybe… six months ago? He used to work the warehouse shift at the co-op. Got fired. He came by the market once, shouting at Britt-Inger. Said she’d ‘poisoned his life’ or something. I thought he was just a nutter.”
“A name, Felix. Do you have a name?”
Felix scrunched his face in effort. “Sten. Sten… something. Malm! Sten Malm.”
Sten Malm’s personnel file was a slim, damning thing. Dismissed for repeated theft of stock and “aggressive behaviour.” His last known address was a run-down apartment block on the town’s outskirts. The landlord said he’d moved out two months prior. “A bitter man, Inspector. Always muttering about how the town owed him.”
As Lundström stood in the empty, stale-smelling apartment, he saw it. Not in the cupboard, but taped behind the toilet cistern: a small, leather-bound notebook. Filled not with recipes, but with formulae. Chemical abbreviations. LD50 ratios. And a list, chilling in its simplicity: Britt’s Buns, Teleborg Seniors, Växjö Fika Festival (June 10).
“He’s working up to something bigger,” Lundström breathed. “The festival. Thousands attend.”
* * * * * * * * * * *
June 10th dawned clear and bright. The Växjö Fika Festival filled the main square with cheerful chaos. Tents offered every conceivable form of coffee and cake. The air was thick with the smell of brewing coffee and sugar. And cinnamon.
Every uniformed officer and plainclothes detective was deployed, eyes scanning the crowd, the stalls, the delivery vans. Lundström, feeling every one of his fifty-six years, moved through the throng, his gaze sharp. He saw families, laughter, the simple joy of a shared pastry. The target was too perfect, the stage too public.
Then he saw him. A gaunt man in the drab overalls of a service company, wheeling a large, professional-sized thermos container on a trolley towards the main festival beverage tent. It was marked “Apple Cider – Spiced.” The man’s eyes darted, not with the harried look of a caterer, but with the furtive, gleaming intensity of a fanatic. Sten Malm.
Lundström moved, cutting through the crowd like a icebreaker through a frozen lake. “Malm!” he called, his voice cutting above the din.
Malm’s head snapped up. Panic, then a twisted defiance. He shoved the trolley violently towards the tent and ran, ducking under a stall banner.
A foot chase through a festival is a unique kind of hell. Lundström barrelled past startled children, around couples, his heart hammering a protest against ribs and years of desk work. Malm was younger, desperate, weaving towards the old cathedral grounds.
He dodged into the wooden storehouse behind the cathedral, used for summer garden supplies. Lundström followed, drawing his service pistol. The dim interior smelled of damp earth and fertilizer.
“It’s over, Malm!” Lundström’s voice echoed in the gloom.
“Over?” a voice hissed from behind a stack of seed bags. “They ruined me! Britt-Inger with her ‘perfect’ business, the co-op with their lies. They took my job, my reputation. I just wanted to give them a taste. A taste of bitterness!”
“You poisoned a swan.”
A bitter laugh. “A test. And it worked.”
Lundström edged forward. “The festival. That would have been more than a taste. People could have died.”
“A message needs to be heard!” Malm screamed, and lunged, not at Lundström, but at a shelf of chemical gardening powders, sending a cloud of white into the air.
In the blinding, choking haze, Lundström heard the scuffle of feet. He dove, not to shoot, but to tackle. They crashed to the concrete floor, grappling. Malm fought with the wiry strength of the unhinged, his hands clawing for Lundström’s eyes. With a final, grunting heave, Lundström rolled, pinning him, snapping cuffs on the thin, straining wrists as the toxic cloud settled around them like a poisonous frost.
* * * * * * * * * * *
A week later, the last of the victims had been released from hospital. The festival cider, upon analysis, contained enough arsenic-laced cinnamon to have caused mass casualties. Sten Malm sat in a high-security psychiatric unit, his notebooks providing a full confession.
Inspector Mats Lundström sat on his small balcony overlooking the quiet street. The evening was mild. Nisse snoozed at his feet. On the little table sat a fresh kanelbulle, from a bakery he trusted, and a cup of coffee. He had just finished a long, meandering video call with Jens, who was full of talk about British essays and the peculiar lack of proper cinnamon buns in England.
Lundström took a bite of the pastry. It was sweet, spicy, warm. Perfectly safe. He savoured it, not just the taste, but the normalcy it represented. The shadow had been lifted from the town, from its kitchens, from its simple pleasures.
He looked out at the gathering twilight over Växjö, the lights coming on in windows, the calm surface of the distant lake. The bitterness, for now, was confined to a cell and to memory. And for a man whose life often tasted of solitude and old regrets, that was a victory sweet enough. He took another sip of coffee, and allowed himself, just for a moment, to simply enjoy the peace.
The end
