Read Chapter 5: The Salt Ring

The light came grey and watery through the field station’s single window when Isla woke. She’d slept badly, the lullaby still coiling through her dreams like weed around a keel. For a moment she lay still, listening. The wind had dropped. The station was quiet. Too quiet.

She swung her legs out of the narrow cot and padded barefoot into the main room.

Tam stood at the centre of the floor, staring down at his own bare feet. He hadn’t moved when she entered. His shoulders were rigid, his hands clenched at his sides.

“Tam?”

He didn’t answer. His jaw worked, but no sound came out. She took a step closer, and then she saw it.

Around his bed—a thin mattress on a low frame pushed against the far wall—was a perfect ring of fish. Mackerel, mostly. A few silvery herring. Twenty, maybe thirty of them, laid head-to-tail in a tight clockwise spiral that began at the foot of the mattress and wound outward across the wooden floor. Their eyes were still bright. Not a single scale out of place.

And the smell. Salt and fresh blood and the deep, ancient reek of the sea.

Isla’s throat tightened. She forced herself to breathe through her mouth.

“Did you—” she started, then stopped. Of course he hadn’t gone out. The door had been bolted from the inside. She’d checked it herself before bed, a habit from years of storm-season fieldwork, when the wind could tear a door off its hinges if you didn’t secure it.

She checked it now again. Still bolted.

She turned back to Tam. His face was pale, almost grey, and his eyes were fixed on the spiral as if it might rear up and bite him.

“I did this,” he said. His voice was hoarse, barely a whisper. “I did this in my sleep.”

“That’s not possible.” Isla’s scientific training kicked in before she could stop it. “The door was locked. The windows are sealed. You couldn’t have gone out and come back without waking me.”

“But I did.” He lifted his hands and looked at them, turning them over as if they belonged to someone else. His fingers trembled. “I dreamed I was swimming. The water was dark and cold, and I was chasing something. Pulling it from the dark. And when I woke up…” He gestured helplessly at the fish.

Isla stepped carefully over the spiral and crouched beside it, studying the pattern. Head-to-tail. Clockwise. The same direction as the spiral carved into the whalebone pendant. The same direction the fish had swum in her dream the first night she’d brought him in from the surf.

Her stomach turned.

“Fish don’t just appear,” she said, more to herself than to him. “They have to come from somewhere. There’s no water source near the station. The nearest beach is two hundred metres away.” She ran a finger along the cool flank of a mackerel. It was damp, but not wet enough to have been carried in a net. No salt water pooled on the floorboards. No trail of moisture from the door.

“I didn’t carry them,” Tam said, his voice cracking. “I swear to you, Isla. I didn’t.”

She stood and faced him. His distress was real. She could see it in the way his hands knotted together, the way his gaze kept dropping to the fish and then jerking away, as if looking too long might hurt him. He had no reason to lie. No way to lie, even, if she were honest with herself—he didn’t even have a name beyond the one she’d given him.

“All right,” she said slowly. “All right. I believe you didn’t carry them in.”

The words felt like a betrayal of everything she’d spent her career learning. Fish did not appear in locked rooms. That was not how the natural world worked. And yet here they were, the evidence on the floor, smelling of brine and fate.

She pulled out her phone. No signal, as usual. She’d have to drive to the village to get a call out.

“What are you going to do?” Tam asked.

“I’m going to call someone.” She grabbed her jacket from the hook by the door. “I have a colleague. Marine biologist at the University of Glasgow. If anyone can tell me what kind of fish these are, where they might have come from, she can.”

“And then what?”

Isla paused at the door. She looked back at him, at his pale face and trembling hands, at the impossible spiral of fish laid out around his bed like an offering. Like a warning.

“And then,” she said, “we figure out what’s happening to you.”

The drive to Taransay village took twenty minutes on the rutted track. Isla made the call from the small post office, standing in the doorway to catch a bar of signal that flickered in and out like a faulty bulb. Dr. Lena Okafor answered on the third ring, her voice tinny through the speaker.

“Isla? You’re supposed to be on fieldwork. Don’t tell me you need me to identify something that washed up again.”

“It’s not something that washed up,” Isla said. “It’s something that appeared.”

She explained as briefly as she could: the locked room, the fish, the spiral. She left out the pendant and the singing and the drowning—herself in the surf, Tam’s skin shining in the dark. She kept it clinical, professional. Fish. A room. A pattern.

Lena was quiet for a long moment. “Weird,” she said finally. “If I didn’t know you better, I’d think you were having me on.”

“I’m not.”

“And you’re sure the doors were locked?”

“I checked them myself. Twice.”

A pause. Isla could hear the soft clatter of Lena’s keyboard in the background, the hum of her office. “You know, mackerel school in large groups. They follow currents. They don’t wander into locked coastal stations.”

“I know that, Lena.”

“But you’re calling me anyway. Which means you don’t trust what you’re seeing.” The words were careful, probing. “What’s going on, Isla? You sound different.”

Isla leaned against the post office wall, suddenly exhausted. She ran a hand through her hair, still tangled from sleep. Outside, the grey sky pressed down on the village, on the wet roofs and the dripping gutters.

“There’s a man here,” she said. “I found him in the surf during the storm. He doesn’t remember anything—not his name, not where he came from. Nothing.”

“And you think the fish are connected?”

Isla closed her eyes. The image of Tam standing over the spiral rose in her mind. His distress. His certainty that he’d somehow caused it. And then, unbidden, the memory of his skin in the moonlight, the faint shimmer of scales just beneath the surface.

“I don’t know what I think anymore,” she said quietly. “That’s the problem.”

Lena was quiet for another long moment. “Send me photos. I’ll run the species, check the migration patterns, see if there’s anything odd. But Isla—be careful, okay? You’re out there alone. And if something’s wrong with that man, you’ve got no backup.”

“I’ll be fine.”

“You say that every time.”

Isla managed a thin smile. “And I’m always fine.”

“One of these days, you won’t be. And I’ll have to come up there to fish you out of the water myself.” A pause. “Literal or otherwise.”

The words landed harder than Lena probably intended. Isla thought of her father, of the way the sea had taken him without a trace. Of how she’d spent her life trying to understand the water, to control it, to read its patterns—and how it kept slipping through her hands.

“I’ll send the photos now,” she said. “Thanks, Lena.”

She hung up and stood for a moment in the post office doorway, watching the clouds roll in over the Sound of Taransay. The water was grey and flat and patient.

Waiting.

When Isla returned to the station, Tam had gathered the fish into a bucket and set it by the door. His face was still pale, but he’d pulled on a jumper and had his hands wrapped around a mug of tea that he clearly wasn’t drinking.

“I couldn’t look at them anymore,” he said.

“That’s fine.” She set down a bag of provisions she’d picked up at the shop. “I sent the photos. She’ll get back to us.”

Tam nodded. He stared into his tea, his reflection wavering in the dark liquid. “Isla,” he said after a moment. “What if I’m not what you think I am?”

She didn’t answer right away. She walked over to the small table and sat across from him, so close their knees almost touched. In the low light of the station, his eyes looked very dark, very clear.

“What do you think you are?” she asked.

He shook his head slowly. “I don’t know. But I feel—when I dreamed that swimming, I felt like I was where I belonged. Like I’d finally come home.” His gaze flicked up to meet hers. “And then I woke up here. And I wondered if maybe I’d gotten it backwards.”

Isla’s breath caught. She reached out before she could stop herself, closing her hand around his wrist. His skin was warm. Normal. Human. But beneath her fingertips, she felt something faint, almost imperceptible: a texture that wasn’t quite skin, a ridge that shouldn’t be there.

He didn’t pull away. But his eyes widened, and she knew he felt it too.

She let go quickly, heart hammering. In her pocket, the whalebone pendant was warm against her thigh.
