The first time they saw the Santa at the end of the pier, it was snowing over the sea.

Not proper snow. Just a dry, dusty drift that looked wrong above the black water. The flakes came in sideways, torn up by the wind, and the tide slapped the wooden supports hard enough to shake salt through the planks.

Luca’s little sister, Emma, tugged his sleeve.

“There,” she whispered. “He is here.”

Luca looked where she pointed.

At the very end of the pier, beyond the last streetlamp, someone waited. A red sleeve hung from a shape that was almost human and almost not. The arm was too long. It bent in the wrong places. Something shiny dangled from the end.

Luca squinted. His breath steamed in front of him; his eyes watered.

He told himself it was just another drunk in a costume. Every year since the disappearances started, there had been people who tried to cash in on the fear. Bad Santas, kids in cheap red coats jumping out from behind fish crates. Videos on TikTok with fake warnings and fake sightings.

Still, something about this one felt different.

No footsteps had approached. Luca had been watching the pier for an hour. One second there had been nothing but snow and dark. The next, that shape was there.

Emma bounced beside him, gloves clapping softly.

“Can we go, Lu? Please. He has my one.” Her voice was firm. Certain. “The one with the silver bow.”

Her cheeks were red from the cold. Her front teeth still had that awkward gap where the new ones were pushing through.

Luca forced a smile.

“It is a creep in a costume,” he said. “Not a real Santa. We are just watching, remember. That is all.”

She did not listen.

None of them ever listened. That was the thing the police talked about on the news. Kids walking away from safe places without hesitation. Leaving coats on benches. Running out of shops and houses and classrooms, always toward somewhere they said was bright and fun and full of presents.

And no one else ever saw what they saw.

“You wait here,” Luca said. “If he is still there in five minutes, I will get Mum. Deal?”

Emma frowned at him with eight-year-old rage.

“If we wait, he will go back under,” she said. “Like last time.”

Last time.

Luca swallowed hard. Three years ago. The first snow of the season. The police tape at the end of the pier. The mothers crying on the local news. Six names. Six bikes left propped against railings, wheels still turning.

The sea had been quiet that morning. Too quiet.

Emma tugged again.

“Lu, look.”

The shape at the end of the pier had started moving. Not walking. Sliding. The red sleeve lifted, and the hand at the end of it uncurled, slow and theatrical.

In its palm lay a small wrapped box.

Even from here, Luca could see the paper. Midnight blue. Tiny silver stars. A neat silver bow. It looked exactly like the paper from the catalogue Emma had circled last week.

His chest tightened.

“No,” he said. “We are going home.”

The word home did not feel right in his mouth. The house since Dad left had never felt like a complete place.

Emma did not argue. She just stepped around him.

“Emma,” he snapped.

She moved past the last streetlamp. The light haloed around her hat and then let her go. For a second she was only a silhouette against the snow and the dark sea and the thing waiting at the end of the pier.

“Emma, stop.”

She did not.

Her boots thudded softly on the wet boards. The wind pushed her sideways, then back. The smell of salt and engine oil and old fish thickened.

Luca’s stomach turned over. He imagined the headlines. The photos. Mum’s face.

He followed.

The air felt heavier as he left the light. The snow changed too. It did not land on his jacket now. It melted before it touched him, leaving only a damp, cold film on his skin.

The figure at the end of the pier brightened.

It was not the lights. There were no lights past the last lamp. The brightness came from the presents dangling from its limbs.

There were more of them now.

Dozens of small boxes hung on strings of what first looked like tinsel. They swayed above the water. Reds and golds, green foil, patterned paper with reindeer and cartoon snowmen. Each one tied with a bow. Each one rocking in a slightly different rhythm, like buoys on a black tide.

Emma slowed.

Luca came up beside her and grabbed her wrist.

“Okay,” he said, breathing fast. “We saw it. We go back. Right now.”

The wind tore the words from his mouth. He had to lean close so she could hear.

Her eyes were wide and fixed on the figure. Her lips moved, counting under her breath.

“That one. In the middle. That is mine.”

“No one sent you anything,” Luca said. “You saw it online and you dreamed it after. This is a trick.”

The figure stepped closer.

The red sleeve was attached to a limb that was not an arm. It bent too many times, with soft bulges, like rope under skin. The hand at the end of it was real enough though. Five fingers. Short, pale nails. Skin too smooth, rubbery in the way of something that had never done real work.

The rest of its body stayed mostly hidden.

The Santa coat clung oddly to its shape. The chest sagged on one side, then jutted on the other. The buttons ran diagonally instead of straight. White faux fur puffed in patches where it should have been trim. The coat stopped too short, revealing slick, grey flesh below, glistening in the snow.

From that flesh sprouted more limbs.

Eight in total, Luca counted numbly. Some bare and glistening, kind of muscular and kind of boneless. Others wrapped in strings of fairy lights that did not need a power source. The bulbs pulsed under the skin like eggs. One limb was wrapped in torn, wet tinsel. Two were completely hidden under draped bags of presents, which bulged and twitched as if something inside them shifted restlessly.

Emma took one step forward, then another.

The hand at the end of the red sleeve extended the blue box with the silver bow.

“Emma,” Luca hissed. “Stop. Please. Do not go closer.”

He dug his fingers into her coat.

She yanked, angry now.

“You do not hear him,” she said. “You never do.”

“Hear who?”

“Santa,” she said, as if it were obvious. “He is singing.”

Luca heard nothing but the sea and his own heart.

The creature’s hand opened, palm up, fingers bent in a beckoning curl.

Smiling, Emma pulled free and reached for the box.

Luca moved without thinking.

He stepped in front of her and knocked the box out of reach. It swung wildly, the silver bow catching his knuckles and leaving a smear of something cold and sticky across his skin.

The creature reacted.

Every light in the hanging presents flared at once. Not white. Not yellow. An electric blue that hurt Luca’s eyes. For a second, he saw the whole shape properly.

It was not a costume.

The torso was an oval mass of flesh, kind of like a squid’s mantle and kind of like an enormous, swollen sac. The Santa coat was grafted into it rather than worn, the white fur growing directly out of damp red tissue. Where a belt should have been there was only a ring of cartilage, banded with broken plastic buckles.

The “hat” at the top was a real Santa hat, soaked and clinging to a rounded bulge. Under it, a single, huge eye stared down the pier.

The pupil was vertical and too thin. The iris was pure, clear green, like the strings of Christmas tree lights in the shop windows on Harbour Road. The sclera was not white at all but a pale grey that seemed to ripple and breathe.

Around that main eye, a cluster of smaller, lidless eyes tracked every movement.

The mouth lay beneath, a slit that ran almost the full width of its body. It opened slightly in reaction to his movement. The edges turned up, as if smiling.

Luca saw no teeth. Only wet darkness and the suggestion of something muscular and thick just behind the lips.

The blue lights subsided.

Emma blinked, dazed. Her breath came in small clouds.

“Why did you do that,” she whispered. “He is nice.”

“Look at it,” Luca said. “It is not nice. It is not even human.”

Her expression changed. Not into fear. Into stubborn, amber-eyed anger that looked exactly like Mum’s when he refused to help around the house.

“You are jealous,” she said. “You always are.”

“Jealous of what?”

“He said I was good,” Emma said. “He chose me. You do not believe in anything, so he does not talk to you.”

The creature’s hand flexed again, patient.

Behind it, the other limbs shifted, rearranging their load of boxes. The strings they hung from were not strings. Up close, Luca could see the muscles inside them, twitching. The paper had small, damp patches where it had soaked in something that was not seawater.

The smell hit him properly now. Salt, yes. And rotting seaweed. And something like opened shellfish left on a radiator. Under it all, a faint note of sugar that made his teeth ache.

The monster moved half a step closer.

It did not walk. It pushed itself along the boards with a gliding, horrible grace, limbs coiling and uncoiling beneath the coat. The wood creaked under the weight but did not break.

It made no sound.

The presents jangled gently as they swayed. A false, cheerful noise, too slow to be festive.

A thought came to Luca, clear and cold, like something surfacing from very deep water.

If it reached them, it would take Emma. The boxes would fold around her. The arms would wrap. That slit would open wider. There would be no scream.

He pulled Emma behind him.

She struggled but he held on.

“We are leaving,” he said. “Right now. I mean it.”

He backed them both away, step by step. The creature did not surge forward as he expected. It followed, but only by inches, keeping the distance between them unchanged.

The blue lights in the packages dimmed to a soft glow.

Luca could feel it watching him. Not just with its eyes. With the whole weight of its attention. A pressure at the back of his neck, at the base of his skull, behind his ears.

Whispers brushed his thoughts. Hissing, gentle, like wrapping paper being folded. He could not quite hear words, but he felt the shape of them.

You are in the way. Move.

You are too old. Let go.

He clenched his teeth and focused on the boards under his boots.

One more step. Then another. The last lamp came closer.

The glow from the presents grew fainter as they left the dark end of the pier. The real streetlamp light washed over them again. Snow settled on his shoulders and did not melt this time.

When Luca risked one last glance back, the creature had stopped.

It hovered at the point where the pier met the open sea, limbs fanned around it in a grotesque halo. The red sleeve hung limp now. The hand had closed.

It looked almost sulky.

Blue pinpricks flickered inside the packages once, then went out, as if someone had flicked a switch.

In the blink between one snow gust and the next, it was gone.

Not walked away. Not slid into the water. Just gone.

Only the dark end of the pier remained, wet and empty.

Emma’s shoulders shook.

“You ruined it,” she said. “You always ruin everything.”

She slapped his hand away. Her glove left a smear of whatever had been on the ribbon.

Luca stared down at his knuckles. The cold, sticky streak had a faint shimmer, almost like glitter. When he tried to wipe it off on his jeans, it clung.

He did not tell Mum the truth.

He tried. He opened his mouth when they got home, still shaking with cold and something that felt too much like fear, but the words would not come out right. Every time he got near “monster” his tongue turned heavy. Every time he tried to say “tentacles” or “eye” his brain offered him softer, safer words instead.

Guy in a costume. Man on the pier. Creepy Santa.

It felt like lying, and also like the best he could do.

Mum listened, half tired, half furious.

“You took her all the way down there at this time of night,” she said. “Do you want me to have a heart attack before I turn forty?”

Luca nodded and shook his head at the same time.

“I pulled her away,” he said. “He was trying to give her something.”

Mum’s mouth twisted.

“If I find out it was one of those idiots from the pub again, I am calling the police,” she said. “No more pier this month. For either of you. Do you understand?”

Emma glared at him over her hot chocolate as if he had personally cancelled Christmas.

In the days that followed, the smear on Luca’s hand did not go away.

He scrubbed. Soap, hot water, nail brush. The glittery sheen faded but never disappeared completely. The skin where it had touched tingled sometimes, like pins and needles.

He had dreams.

In them, he stood at the end of the pier. The sea was calm as glass. The snow hung motionless in the air like dust in church windows. From beneath the water something glowed, just faintly. A blue pulse, rhythmic and slow, like the heartbeat of a sleeping animal.

A voice hummed under the waves. A tune almost, but not quite, Jingle Bells. The notes missed the last beat of each bar and fell into strange places. Between the bars, between the pauses.

He would wake with salty taste at the back of his throat and the feeling that he had swallowed something small and sharp.

The town turned itself into tinsel as December crept closer to the twenty-fifth.

Lights along Harbour Road. A crooked plastic tree in the corner of the Co-op. Posters for the Christmas Eve market on the high street. An official statement from the council saying the pier would be “partially closed for maintenance” until the new year.

Everyone knew what that meant.

Luca sat in class and watched other kids draw snowmen and write letters to Santa. When he accidentally looked too long at the cotton wool and paper decorations on the classroom window, the white fluff seemed to ripple like foam on a wave. The red card circles looked too much like staring eyes.

He stopped going to sleep without a fight.

On the twenty-third, he found Emma in the hallway with her coat already on at eight in the evening.

“Where are you going,” he asked.

“To see my friend,” she said.

Her eyes glittered with the same stubborn certainty as the night on the pier.

He blocked the door with his arm.

“You heard Mum,” he said. “No pier. She will ground us until Easter.”

“I am not going to the pier,” Emma said. “He has a house.”

Luca laughed, because the alternative was something worse.

“Santa lives in Lapland,” he said. “Not in Poole.”

“Not him,” she said. “The other one. The wet one.”

The world seemed to tilt.

She said it calmly, as if she were telling him about a new friend at school. The wet one. Like she had given it a nickname.

“Emma,” he said slowly. “When did you see him again.”

“Last night,” she said. “In my dream. He showed me where he sleeps.”

Her voice softened, dreamy. A kid talking about a secret den.

“It is beautiful,” she said. “So many presents. A bigger pile than the shop windows. He said I can climb on them. He said he saved a place for me.”

Luca’s spine felt cold even though the heating was on full.

“He is lying,” he said. “That is what he does. That is what Mum always says about men who give kids stuff and ask them to keep it secret. It is not nice. It is bad.”

“This is different,” Emma said. “He is lonely, not bad.”

“How do you know?”

“He told me,” she said. “He does not have any children who stay with him. Only pieces.”

Pieces.

Luca grabbed her shoulders.

“Where,” he asked. “Where is his house.”

Emma narrowed her eyes.

“You will just tell Mum,” she said.

“I will not,” he said. “I swear. Just tell me.”

She looked at him for a long moment.

“At the bottom of the pier,” she said eventually. “Under the last post, there is a ladder. It is hidden in the slime. You have to look sideways or you cannot see it. He said when the tide is lowest, you can climb down into his chimney.”

“His chimney,” Luca repeated.

“The hole,” she corrected. “The gap in the rocks. It smells like when we open the fridge and something is wrong, but you get used to it. He said it is a special smell. It means you are close.”

He nearly threw up.

The next low tide was at three in the morning.

He knew this because he sat on his bed with his phone in his hand, watching the tide charts in the dark while Emma snored softly in the next room.

Mum was working a night shift at the care home. She had kissed them both on the head at eleven, promised them pancakes on Christmas Eve, and left her tired smell of cheap perfume and instant coffee behind.

The house creaked around him as the wind picked up.

Luca pulled on his hoodie and his thickest socks and stood in Emma’s doorway.

She was curled on her side, hands tucked under her cheek. Her curtains had little gold stars on them. Glow in the dark. They shone faintly in the room.

He could wake her and drag her to the sofa and sit on her until morning. He could lock the door and call Mum and make it her problem. He could pretend the whisper in his head was not real.

The whisper said something simple.

If you stop her once, he will just try again.

If you do not see where she is going, you will never find her.

He put her door on the latch, so it would click louder if she opened it.

Then he left.

The town was ugly at three in the morning.

All the lights were off except the odd security lamp. The Christmas decorations were just dark shapes hanging from lampposts and shop fronts. The snow had stopped, but the cold had deepened. His breath came out in slow ghosts as he walked.

The pier gate was locked with a chain. A fresh sign hung on it with a polite warning about maintenance.

Luca climbed the side railing instead.

The sea muttered below. Dark, slow swells pushed against the supports. In the distance, a buoy bell clanged occasionally, its pitch flattened by the wind.

The smear on his hand tingled more with every step.

The end of the pier felt different in the dark.

Without the streetlamps, the boundary between wood and sea and sky blurred. The horizon was just a slightly paler line. The air had a thickness he recognised now, an invisible curtain like the one that sometimes hung at the greenhouse doors when Mum took them to the garden centre.

He walked until the last post.

The slime he had always avoided in daylight took on a greenish sheen with each swell.

He looked sideways.

It was a ridiculous thing to do, and he felt ridiculous doing it, but he did it anyway.

He did not look at the wood directly. He unfocused his eyes, like one of those magic picture books from when he was smaller. He pretended he was trying to spot dolphins out in the dark, not the pier under his feet.

At first, there was nothing.

Then, where the dripping posts met the sea, something straight appeared behind the layers of algae. Too straight to be natural. Too regular. Like the suggestion of rungs.

His heart pounded.

He moved closer. The smell reached him a moment later.

It was exactly as Emma had described.

Not just rot. A layered smell. Seaweed going soft. Old blood in metal pipes. The sweet chemical tang of air freshener failing to hide cat piss. The inside of the fish shop after closing time.

His stomach tried to invert itself.

He swallowed and climbed over the side.

The first rung was slick, but his fingers found purchase. The slime felt warm where the rest of the metal was freezing. It pulsed faintly under his hands, as if the wood and metal and algae shared a heartbeat.

He went down.

The sea slapped his shoes and climbed his jeans. The water was low enough that he could keep going. He reached a ledge instead of waves.

A cut in the rock opened in front of him.

In daylight it would have looked like nothing. Just another seam. In the dark, it breathed.

The air coming out of it was warmer. Wet. It carried the smell from before, multiplied.

Luca gagged and half fell sideways into the passage.

It sloped down. The walls were slick and close. He could not stand fully upright. His shoulders brushed both sides.

Something sticky brushed his hair.

He wiped his head frantically and felt strands come away on his fingers. When he brought his hand close enough, he saw a faint blue smear on his skin, like diluted ink.

He wanted very much to turn back.

He kept going.

The tunnel widened gradually until he could walk without ducking. The ceiling curved above him in a perfect arch. No tool marks. No bricks. Just smoothed stone, like the inside of a thousand-year-old cave.

Lightning flashed ahead.

Not real lightning. A brief, intense blue flare, as if someone had turned on a single, enormous LED for a heartbeat.

He heard bells.

Not many. Just a few notes that echoed strangely in the enclosed space.

He stepped into the den.

The first thing he saw were the presents.

They rose from floor to ceiling in a huge mound, blocking most of the chamber. Boxes of every size. Some fresh and bright. Others faded and sagging. Rips in the paper showed cardboard and, in places, something else underneath.

The colours were festive. The shapes were not.

In some spots, the boxes had fused together, melted into one another like wax. Bows had grown into loops of tendon. Ribbons had become veins. Light twitched under the paper, revealing ribs and long bones and round shapes that could only be skulls.

Children’s skulls were smaller than he had imagined. That was the thought that came to him. Not horror. A plain, shocked observation.

Some of the bones were clean and white. Others still had tatters of something dark on them.

The mound shifted.

Not a ripple this time, not the nervous rustle of box lids lifting and settling. The whole pile rearranged itself with purpose. Presents slid and locked together, paper tightening, ribbons cinching, bows pulling taut as if drawn by invisible hands. The sound was soft and intimate, like careful wrapping done late at night.

Something rose from the centre.

At first it looked like the pile was becoming a person.

Boxes stacked themselves into a crude spine. Wrapping paper smoothed into a torso. A Santa costume unfurled from within the mound, not worn but assembled, sleeves threaded over unseen supports, the coat hanging where a body should have been. Suckers pressed through the fabric in pale, circular blooms, pinning the costume in place.

Then the head emerged.

A large square present, wrapped in glossy red paper, crowned with a Santa hat like a decorative lid. The hat was damp. The white trim pulsed faintly, alive in a way fur should not be. A seam split across the front of the box, opening and closing like a mouth learning performance.

Through a torn corner of the paper, the main eye stared out.

It blinked once, slow and indulgent.

A puppet Santa, built from gifts, upright and festive and wrong. The limbs holding it aloft remained mostly hidden, but when the blue light flared beneath the paper, Luca saw them braced underneath, thick and coiling, suckers biting through cardboard to keep the shape standing.

One limb wore the familiar red sleeve.

The hand at its end lifted.

In its palm rested a present wrapped in midnight blue paper, silver stars scattered across it, tied with a perfect silver bow. The kind of bow tied slowly, carefully, by someone who wanted it to look right.

The cavern brightened with a soft internal pulse.

Luca’s knuckles burned.

The mark on his hand flared, not on the surface but beneath it, as if the light had found a path through his veins. His fingers trembled, then steadied against his will.

The Santa puppet leaned closer.

The seam in the box-head widened. Inside was not darkness, but a soft glow, like snow caught in lamplight. The bell-noise returned, gentle and coaxing, and Luca realised with a jolt that it wasn’t coming from the creature at all.

It was coming from him.

A whisper slid through his skull, warm and patient.

Open it.

Just look.

His arm lifted.

He took the present.

The paper was warm. Damp at the corners. The bow was slick, too smooth to be ribbon.

The mound behind the puppet rustled, eager. Boxes pressed inward, forming a loose circle, paper faces turned toward him like an audience waiting for the trick to land.

Luca tore the bow.

The paper split cleanly.

The lid lifted.

For a moment, his mind refused to name what it saw. It tried to rearrange it into something harmless. Something festive. Something that could not break him.

Inside the box lay a careful arrangement.

Emma’s pyjamas.

The soft cotton set she wore on cold nights, folded neatly, sleeves tucked in, still faintly creased from sleep. A slipper lay beside them. The sheep one. One ear bent. The missing bead eye staring like it always had.

Beneath the fabric, bone and soft anatomy pushed outward, pressing and distorting the cloth from within: a small hand, eyes, fingers twisted, folded, and laced together, their shapes disciplined into place, coerced into the grotesque arc of a Christmas garland. Nothing hung naturally. Every curve spoke of pressure, of intent, of something carefully made wrong.

His sister was no longer a body, nor even a presence, but a pattern. A festive display. An arrangement meant to be looked at, admired, and mistaken for celebration.

Luca staggered back, the present slipping from his hands and hitting the stone floor with a soft, padded sound. The glow spilled out through the torn paper, washing the cavern walls in blue. The mound answered it, boxes shuddering, ribbons tightening, bones clicking faintly as if settling into a more comfortable position.

The puppet Santa leaned closer.

The eye in the box-head blinked, slow and indulgent.

The whisper returned, no longer coaxing. Certain now.

You understand the rules.

You stopped her.

So you stay.

The cavern seemed to inhale.

The floor beneath Luca’s feet softened, no longer stone but something yielding, warm, faintly ribbed. His boots sank a fraction of an inch. He tried to step back and found no purchase. The air thickened around him, heavy with sweetness and rot, pressing against his chest.

The present at his feet slid, drawn by the same quiet force that had raised the puppet. It nudged against his shin, then tipped, spilling its light across his legs, his hands, his face.

The mark on his knuckles flared violently.

Pain bloomed, sharp and cold, then dulled into pressure. Not tearing. Not cutting. A sensation of being folded. Of angles rearranging themselves. Of something learning his shape.

The mound opened.

Boxes parted with reverent care, creating a space just wide enough for him. Ribbons brushed his skin, tightening as they passed. Paper pressed against his back, damp and warm. Suckers closed briefly on his coat, anchoring him, guiding him.

Luca screamed once.

The sound didn’t travel.

It softened immediately, absorbed by the cavern, by the paper, by the flesh beneath it. It came back to him altered, stretched thin and rhythmic, a note that slid neatly into the wrong carol humming through the stone.

The puppet Santa straightened.

Another present slid into place at its side.

Midnight blue paper. Silver stars. A neat silver bow.

The mound settled.

The light dimmed.

The den became still again, patient and full.

Emma woke before the alarm.

She lay still for a moment, listening. The house felt different. Not quieter. More… arranged. Like furniture moved in the dark.

A soft blue glow pulsed at the edge of her vision.

She sat up.

Moonlight leaked through the curtains, but that wasn’t it. The light was coming from downstairs. From the living room.

Emma padded out of bed, the carpet cold under her feet. The hallway was dim, but at the bottom of the stairs she saw it clearly.

A present sat beneath the Christmas tree.

It hadn’t been there when she went to sleep.

Dark green paper. A red bow tied too tight, the loops pulled sharp, almost strained. Blue light breathed through the seams, slow and steady, like something alive inside the box.

Emma descended the stairs without calling out.

The house didn’t creak. It didn’t settle. It felt as if it were listening.

She knelt in front of the tree.

The light reflected in the ornaments, bending her reflection, thinning it, stretching it. Her face looked older for a second. Or maybe smaller.

She reached out and touched the box.

The paper was warm.

Through a slight tear near one corner, she glimpsed something pale beneath. Not clearly. Just enough to suggest a curve that might have been cardboard. Or fabric. Or skin pressed too close to the surface.

The light pulsed brighter.

Emma smiled.

“Oh,” she whispered. “You came back.”

Upstairs, Mum slept on, dreaming of nothing at all.

And far below the pier, where the sea never quite stilled, the mound of presents hummed softly to itself, satisfied, having learned a new shape, and prepared already for the next one.
