The City of Woven Streets. Emmi Itaranta

every year after the Ink-marking,’ Alva replies. ‘Do these seem the same to you?’ She points at two grey strips on top of the mirror. A scent of mud and seaweed rises from them. I look at them more closely and notice that they appear to be slices of medusa flesh.

      ‘Exactly the same,’ I say. ‘Why?’

      Alva places the mirror under the microscope lens and pulls one of the lanterns closer. She looks into the microscope and adjusts it by the wheel on the side.

      ‘What about now?’ she asks.

      I walk around the table next to her and peer into the microscope. The view makes me think of trunks of strange trees, a pile of maggots or budding branches of unfamiliar sea plants.

      ‘You’re looking at the part of medusa skin that helps them feel and sense light. It also contains their medicinal properties, the cells that produce a pain-relieving chemical,’ Alva says. ‘There are samples from two medusas under the lens, not just one.’

      The difference is clear. The tree-trunk and budding-branch patterns on the left look translucent, but on the right dark streaks show on them, as if they have been dipped in ink that is slowly dripping off.

      ‘What is that?’ I ask.

      ‘I asked someone to bring me a dead medusa from the shore, the freshest they could find,’ Alva says. ‘That’s the one on the right. The other one is from my tank.’

      ‘I thought they all died of polyp fever.’

      It has been a week since the flood. A few days after the first wave of dead medusas washed to the shores, the Council sent a water message around the city. The word spread quickly: polyp fever, a rare disease that was not harmful to humans but could become an epidemic. Unfortunate, because it would take years for the medusa population to recover. Ships had already been sent to collect healthy singing medusas from the open sea to be planted in the waters close to the island.

      ‘That’s what I thought,’ Alva says. ‘But then I began to wonder. Polyp fever doesn’t usually strike during the cool season. According to lore, there have only been three epidemics on the island before, and they all took place in late summer.’

      I remember the mute and still blooms of jellyfish that people are still collecting from the streets and shores, their stench that floats around the midden ships. I think of the humming of the medusas in denser-growing evenings, the silence spread across the shores, and the air feels heavier to breathe.

      ‘What is it, then?’

      ‘I don’t know, but it is not polyp fever. Could be a different kind of disease.’ She reaches for the side table and picks up two glass jars with water and a dead medusa in each. The animals are missing a slice of their bells. ‘There’s something else, too,’ she says.

      Alva walks across the room to the tank and pushes one of the jars against the glass wall. Inside the tank, a bloom of medusas begins to gather near the dead one, and a faint humming grows in the water. The medusas settle into the shape of a circle and the slow gauzes of their swimming-bells ripple behind the glass. Alva waits, pulls the first jar away and presses the other one against the tank. The singing medusas keep their formation for a moment, some of them even swimming closer in curiosity. Then the humming is cut short, and all goes quiet. A few seconds later the whole bloom bursts like a large soap bubble. The medusas scurry in all directions, far away to the other side of the tank.

      ‘Have you ever seen them do that?’ Alva asks.

      ‘No.’

      ‘Neither have I.’ Alva turns and walks back to the table. Only after some time do the medusas return to their languid paths in the water-space.

      ‘What are you going to do?’ I ask.

      ‘I don’t know yet,’ Alva says. ‘I need to look into this further.’

      I will soon be missed in the Halls of Weaving. You can stretch a temporary absence from work for a while, but you have to do it carefully.

      ‘Weaver asked me to tell you that she wants to move the patient to the Hospital Quarters tomorrow,’ I say. ‘The … visitor.’ My hand has moved to gesture at my mouth before I realize, and Alva needs no further specification. She nods.

      ‘Good. I’ve already had to put spare mattresses to use. A severe cough is spreading in the house, and it seems to come with a dreadful rash.’

      ‘Is it contagious?’

      ‘Presumably,’ she says. ‘Do you want to come and say goodbye?’

      I glance in the direction of the Halls of Weaving.

      ‘I will take full responsibility if Weaver comes after you,’ Alva says. ‘Medical emergency.’

      ‘Offer accepted,’ I say, more out of temptation to stay away from weaving a little longer than anything else. Or so I tell myself.

      Alva leaves the glass jars with dead medusas on the table and we head into the other room.

      There is more light today, and sound, the kind created when you put many people in a small space and tell them to rest but they are in too much discomfort to do so. Two spare mattresses have been wedged in the narrow gaps between the beds. There are three younger weavers and four older than myself in the sick bay. Two seem asleep, but the rest are tossing and turning restlessly. Their breathing is distorted and ragged, heavy with cough. Their skin is covered in a rash that looks like they have been dipped in red or purple ink. I smell the heavy scent of burning herbs, and under it sweat and sickness.

      The girl is awake. She is sitting at the back of the room, propped up with pillows, and is putting together a puzzle. Alva must have given it to her. She turns to look at us. Alva puts a jar under the girl’s chin and she opens her mouth. A dead singing medusa drops into the jar.

      ‘I’m afraid I cannot give you another one,’ Alva says. ‘I don’t know when I will be able to get more, and I need to keep a few in reserve.’

      The girl nods.

      ‘But I have good news,’ Alva continues. ‘We can finally arrange your transfer. It wasn’t possible earlier, because there was an accident in the north.’ I remember the flood night: the empty sky, the missing cable. ‘An important air route crashed the night you came. Cleaning up has caused so much work that the route has only just started operating again.’

      The girl looks like something is troubling her, but nods again slowly. Her face begins to darken in a way I do not understand.

      ‘A gondola is coming to take you to the Hospital Quarters tomorrow,’ Alva continues. ‘They have more singing medusas. And if not, they’ll have something else to ease the pain.’

      The girl’s face continues to darken. She takes a deep breath and stares at Alva.

      ‘What is it?’ I ask.

      She grasps my wrist. I start, but do not pull my hand away. Her fingers are warm and narrow, and their grip seems to reach deeper than the skin. I glance at Alva.

      ‘Everything is fine,’ I say to the girl. ‘There will be more space in the Hospital Quarters. They will be able to take better care of you there and find your family.’

      The girl holds my gaze with hers: grey as rain, or floodwaters in the light of dawn. A slow shiver travels through me, as if she is pulling an invisible string somewhere inside. The corners of her mouth tremble once, she draws breath again, and then lets go of me, turning her face towards the floor. She is very still, as if holding a deep tremor within.

      ‘I just came to say goodbye,’ I say.

      The girl raises her gaze. She nods slowly.

      ‘I hope you feel better soon.’

      They are worn and hollow words, but I cannot find any others.

      Before I turn to go, something moves in her eyes. A knot tightens inside me, but I choose to treat it as just another shadow. One more
