The Whispering Lighthouse stood on the edge of the cliff, as if it was about to take a step over the black water. In winter, when the wind cut like thin glass, the light went out early because the boats hardly went out to sea, yet people still came to the wall at dusk to speak their business to it. They said the walls gave back what the waves had taken away - echoes of names, unsaid requests, reconciliation with someone who had not returned. They called it the Lighthouse of Whispers, though no one remembered who first started whispering. Lena returned to Zawietrzyn on the late train, with her suitcase banging against her ankles and a wooden casket pressed against her ribcage in a thick jumper. The snow was different here than inland - powdery and salty, creaking as if it were cracking meaningless glass. The smell of rust and iodine was already wafting around from the station, pressing memories into her lungs. As a child, she could tell by it whether a storm was coming or just the long-awaited day after low tide, when the discarded things on the shore said more than many a newspaper. - 'You're late,' Aunt Mira said as Lena climbed the steep steps of the lighthouse. She never asked if the girl would be back for longer. She always said 'when', as if the future was a glove that could be slipped into her hand without a second thought. Auntie smelled of ink and parchment as she wrote all her life in the Book of Trails - a thick register full of maps, words and dashed lines that made up stories of currents, stars and human choices. In Zawierzyn in the past, lighthouse keepers didn't just crank the lens; they were chroniclers of light. Lena set the casket on the table. It was scuffed by her fingers and had a crescent-shaped scratch in the corner. Three figures were engraved on the lid: compasses, a wave and something that resembled an eye slit with light. - 'You still have it,' Mira remarked, without surprise. - 'I got it... from him - Lena couldn't pronounce the word 'dad', as if her tongue was resisting the urge to connect the past with her breath. Three years ago, Nikolai disappeared at sea when the night was so hard that ice needles grew on the railings at a whispering pace. Nothing was found, not even a shred of sail. The water in the pipes murmured a long sound, almost singing. Lena looked over, reflexively - as a child it had seemed to her that the pipes in this lighthouse had their own language, which she had to learn to read between the drops. Now the pipes played two notes, as if someone had tumbled over the silence. - Are you going to stay? - Auntie asked. - 'Until the end of the holidays,' replied Lena. - I wanted to see... - Her gaze escaped to the stairs that climbed to the head of the lighthouse. She remembered them by heart: every creak, every worn-out rung, every nail, under which she had hidden, at the age of nine, a pearl of find, which later turned out to be a piece of glass. In the morning there were thick clouds in the bay, but the onshore wind was stroking the sea flat. In the harbour, nets were being repaired unhurriedly, and old women sat on cod cases and told each other what they had said to the lighthouse yesterday and what the lighthouse had taken from it. Lena walked down to the quay. She saw Iwa, who was drawing with charcoal on the deck of his boat, although he could read the water better than his own hand. - 'You've got a look on your face like you've come back from a place where the calendar doesn't have pages,' he said, putting the charcoal down. He wore a jacket too big by a number because he said his body was just catching up with life. He was smiling with one corner of his mouth - the other was listening. - 'And you're trying to make up nautical proverbs again,' Lena repaid him. - If you don't feed the rolling light, you have to feed the words? - There's going to be a backwater today - Iwo looked towards the cliff. - That trough may be exposed at night, something that doesn't happen every year. They say that when the ground shows you something you weren't ready to see, it's better not to touch. Backwater. Lena felt it in her teeth, as if the saliva was thickening. A backwater meant that the sea would take a step backwards and show a bottom that ordinary eyes don't walk on. It was always then that objects disappeared from the attics: the old clock would lose a minute, the temperature in the houses would drop one degree, and the cats would stop blinking as if they wanted to count the air. - And the Hour of the Nameless? - She asked, not knowing where the word had come from within her. Iwo drew in a breath. - 'Who told you? - The pipes - the joke had an unpleasant taste. - And... once, a long time ago, Dad. That there is a night when the clues get tired. That the lantern then has a rule. - The rule is shorter than the spell, and it lasts longer - chuckled Iwo. - Never turn on a light at a time that is not there. This was written still by the old Whirlwind on the railing where they all put their hand. The name Wicher was known to every child here. Rose Wicher was the last one who knew how to spin a lens so that the course of light drew even lines on the water, as if she were guiding a transparent map with her finger. She retired a year before Santa disappeared. Some said she knew how to talk to the lighthouse no worse than to people. That same afternoon, Lena saw something that made her squint for a moment as if before the sun. Aunt Mira had left a bag of coarse salt on the kitchen counter. The salt spilled out, forming clumpy footprints. Lena was already about to scrape it off with her hand when she noticed that the crystals had formed into letters. Her skin trembled under her jumper. Come when the clues stand. The key fits into the refractor. Trust the light. Dad. The word 'Dad' was soaked, with the left side seemingly lighter. Before Lena could call out to her aunt, the wind hit the window and salty grains scattered to the corners. Mira entered, carrying transparent sketches of streamlines, and registered nothing unusual except that the floor squeaked again like a forgotten aisle in a theatre. Lena sat down on a stool. She opened the casket. Inside lay a brass key. It did not look like a door key - for it had no teeth, only a leaf-shaped slot with swirling grooves. On its handle shone a tiny convex drawing, reminiscent of a map, but no one had left a legend. When she took it in her fingers, the key trembled, as if it recognised a pulse. For a moment, Lena stood at the window, the lantern watching her from its glass eye. She remembered her father's hands on the key of the oil locker, remembered him leading her up the stairs and saying: "The light thinks". Not 'shine', not 'burn', just 'beware'. For Nicholas, light was a thing, not a thing. Evening came from the land side, first in a grey ribbon stretching across the fields, and then darkened as if someone had poured ink into the mist. The cats disappeared from the doorsteps. Even the chains were quiet in the harbour. Only the pipes sounded again - this time with three short sounds, as if someone was running a finger along the rim of the glasses. Iwo came under the lighthouse with thermoses - one with tea, the other with courage, as he said with a smile that did not reach his eyes. - 'I'll follow you if you need me,' he announced when Lena told him about the salt and the key, though a thread of anxiety almost broke in his voice. - 'But I know the rule. I also know what is said about those who break it. - He looked at her hand. - Maybe you don't break it. Maybe you'll rewrite it. - Rewrite it? - She repeated, surprised that the word had even come up here. - Rules are like maps. Someone draws them, someone else has to check that the bat hasn't grown into a span that has been forgotten. - He hesitated. - Just... be careful. - He pointed to the balustrade, across which the worn-out letters formed the phrase: Be a guardian of what you don't understand until you do. As the clock in the market passed over twelve o'clock and the sound spread sharply across the wet tiles, something in the night trembled. Lena felt it in her knees and down her spine, as if there was another clock living in her body that suddenly did a 'stop'. The hands of all the clocks in Aunt Mira's house stood still in a place that was no number. The windows went darker than usual. A breath blew in from the water, but it was not a breath of wind. The reef had taken the sea so far out that the bottom shone flakily in places where it never shone. - It is she,' Iwo whispered. - The hour you will not write down. Lena tightened her fingers on the key. They went out onto the stairs. Each step groaned, but differently than always - not with their own groan, but a repetition of other people's voices. The girl heard her own 'mum' from years ago, her aunt's voice reading her a map of the stars, and the rubbing of Rosa Wicher's pen as she took notes with a knife across the wood because the ink had taken offence. The walls were chilly, the metal of the handrail's handle biting into her skin like the blade of winter. The lantern head was a transparent house where glass and sanded metal arranged themselves into a cathedral of silent geometry. The Fresnel lens stood like a huge teeming eye, composed of hundreds of glass feathers that could catch the beam and teach it humility. In the middle of the device, fragile pendulums, scales, silent gears - everything was asleep, but Lena felt a tremor, as if someone was slowly waking up the mechanism by the touch of air. - 'Where are you going to put this thing? - asked Iwo in a whisper, because otherwise he probably wouldn't have been able to speak to the lens that was looking at him even before he saw it. - 'Here,' Lena touched the base - a massive old refractor with hundreds of hands embedded in the metal. Underneath, scratches that might have been random were arranged in hidden marks. There was something between the two screws that she had not been able to see as a child: a narrow gap, almost invisible, slipped in at the ends. When she applied the key, it fit just as dreams fit, even though they happen in different heads. Before she turned it, she looked towards the bay. Glass framed the frame of the world. The bottom, exposed by the retreat, looked like a sheet on which someone had cut ornaments with a thin needle. The cuts were arranged in lines - one leading straight towards the cliff, the other zigzagging to the island, where apparently only those who wanted to find a new way home were camped. Something glittered between the lines, as if someone had scattered the cinders of stars and not picked them up after work. - What if... - Iwo began, and did not finish. His caution snapped and he fell to the floor, the echo eating away at him like his own tail. Lena turned the key. First there was a warmth that had no source. It flowed like a torrent upwards, not downwards, passed through their chests and made itself comfortable under their collar bones. Then there was a sound. It could not be heard with the ears; it could be felt with the skin. It was like a clear 'yes' spoken in an empty church. The lens opened from the inside: more rings twitched, as if someone's hand was placing pawns of light on a board they did not know. From the lamp, though no bulb was burning, threads blossomed - thin as hair and razor-sharp. These were not the beams they knew from the lanterns that warn ships. These threads did not fly into the distance, but stretched space like the wires of a harp. She felt that if she touched one of them, the world would say "look". On them, for a second, a figure appeared. A man, walking through water that wasn't there, in an unbuttoned coat, with his hair stuck to his forehead. The face - which she knew better than her own corridors of elbows - lifted towards them. It wasn't like the one in her memories. She was newer. Nicholas didn't look like the one who had disappeared; he looked like the one who was returning. - 'Daddy,' she snapped out, but her voice was bogged down by the glassy interior of the lantern. The figure blinked, as if something in his world had just popped into his eye. Then it went out - not like a flame, but like a photograph that someone had slipped into another book. - 'I saw,' Iwo didn't manage to finish his sentence, because neither of them was sure whether what they saw was an image, a reflection or a crack in time. A sound came from below, as if a large hand had touched the bay window. The bottom spoke, the metal of the lantern responded with a short hiss. On the floor, amid the scratches and nicks of keys that no one had worn for years, a thin crack was outlined. Not in the floor - in the light. It was as if this light was the floor, and underneath it was another room. - 'Don't touch it,' Iwo said reflexively, but his hand, which had reached for her wrist, stopped before he touched it. - Or maybe that's what you need to do. The pipes played. Briefly, questioningly. Lena felt the lantern looking at her, not just with a lens. The screws were looking at her, the wood, the water in the pipes, the dust on the window sills, the paper in the Book of Trails. Her right hand ached from squeezing the brass. Something moved in the gap - from underneath, as if someone was climbing the stairs that were invisible from their side. - 'Leno,' said the air. Not like a voice coming out of the throat. More like a shadow of a word. There was salt in it and something that smelled like rain before July. The threadbare lights stretched tighter until the windows trembled. Outside, the sea parted a step more, sizeable as the breath of a huge creature. Marks flashed across the exposed bottom - not letters, not numbers, but engraved lines that might have been a map or a promise. One of the lines, the one leading straight up to the lighthouse, pulsed like a vein. Each pulse clashed with the way the key pressed against her skin. - Leno - this time the word came out of the very crack. As if someone from the other side stood behind a door that was made of light and silence. - Open. - Can you hear it? - asked Iwo through his teeth, for his voice could not pass for amazement. Lena did not answer. She hovered over the crevice. A chill blew in from the depths, but not the kind she knew; there was the barely perceptible smell of grass in the middle of winter, the laughter of a day that had not yet happened, and the taste of tears that might not have been hers. On the other side, something scratched the light - gently, like a fingernail against the surface of a mirror. It thundered - not in the sky, but in the lantern structure. The bolts tightened like strings. And at the same moment they heard a distinct knocking, familiar and therefore more terrible than anything else: once, twice. Two quiet knocks on a door that should not have been here at all. A third time the knock sounded. The doorknob, which they could not see, moved from underneath.
