Summary

On a stormy October weekend, fourteen-year-old Mira is left alone on a tidal island when her grandfather, the last lighthouse keeper, is rushed to the mainland. A coded note in his logbook warns that a boat will be steering by the old light that very night, hours before it is due to go dark forever.

Transcript

0:00The Last Weekend

The island of Carrick Holm is only an island twice a day. When the tide drops, a ribbon of wet stone appears, a causeway curling out from the northern mainland. When the tide returns, the sea swallows it whole, and the island belongs to the wind, the gulls, and the lighthouse. Fourteen-year-old Mira Okonjo arrived on the Saturday of the October half-term with a rucksack full of puzzle books and a grandfather waiting at the end of the stones. Elias Okonjo had kept the Carrick Holm light for thirty-one years. The lamp ran itself now, automated decades ago, but Elias had stayed on as its keeper anyway, polishing brass that no one inspected. And on Sunday at midnight, the light would be switched off forever. That first evening, at exactly six, the great clock in the tower chimed. Elias lifted his wristwatch, nudged the crown, and set it by the sound. 'Every night for thirty-one years,' he said. 'That clock has never once been wrong.' Mira smiled. Then she noticed a single headlamp bobbing across the causeway in the dusk, moving fast, as if someone were racing the sea.

1:02The Engineer Arrives

The stranger was soaked to the knees and already checking his watch. 'Desmond Hale,' he said, shaking water from a hard-cased toolbox. 'Decommissioning. I'll be doing the final shutdown tomorrow night.' He was tall and brisk, with a way of looking past people as if they were standing in front of something more important. Over supper he explained the plan. The last of the Victorian clockwork still drove the lamp's master timer, a quirk the engineers had never bothered to modernise. He had fitted a trip switch to it. When the clock struck twelve on Sunday, the light would go dark, and he would sign the papers and be gone. 'You don't like the sea much,' Mira said, watching him flinch each time a wave boomed against the rocks. 'My family's had enough of it,' Desmond said flatly. 'My brother fished these waters till it nearly drowned him. He swore off boats years ago. Only sensible thing a Hale ever did.' Elias said nothing. But later, Mira found her grandfather at the tower window, staring into the black strait, whispering the same words again and again. 'Not yet. Not tomorrow. Not yet.'

2:05The Fall

Sunday came in grey and furious. By afternoon the wind had torn a slate from the store-shed roof, and Elias insisted on fetching it before it smashed a window. Mira watched from the doorway as he picked his way across the weed-slick rocks. Then his boot skidded. He went down hard, one leg folded beneath him, and he did not get up. Mira ran, her phone bouncing from her pocket into a rock pool. She didn't stop for it. Her grandfather's face was grey with pain, but his eyes were clear. Together with Desmond, she got him into the shelter of the doorway, and Mira called the harbour on the big lighthouse radio. A calm voice answered: Rosa Penhallow, the harbourmaster. Within the hour, a lifeboat was nosing into the island's tiny landing. As the crew lifted Elias onto the stretcher, he caught Mira's wrist. He unbuckled his watch with trembling fingers and pressed it into her palm. 'Mind the clock, Mira,' he gasped. 'Mind the—' The lifeboat engine roared, swallowing the rest, and her grandfather was carried away into the spray.

3:04The Coded Note

The lighthouse felt enormous without him. Mira tried the radio again to ask for news, but the handset only hissed. Outside, a broken aerial cable whipped against the tower like a loose rope. The storm had cut them off. Desmond appeared in the doorway, briefcase already packed. 'Causeway floods at high tide,' he said, nodding at the tower clock, whose hands stood at nine. 'Midnight. That gives us three hours. When the clock strikes twelve, the light goes out, I sign off, and we walk across together before the water closes. Get your things.' But Mira had seen something. Her grandfather's logbook lay open on the desk, the last entry dated that morning. Below the usual notes on wind speed and visibility was a line of letters that made no sense at all. NLWWLZDNH. KRPH. VXQGDB. Dozens more like them, underlined twice, hard enough to tear the page. Her grandfather never underlined anything. He was a man who wrote puzzles into birthday cards and hid riddles under teacups. This wasn't confusion. It was a message, and it had been written for someone who knew how to read it.

4:09Breaking the Code

Mira's puzzle books had taught her one thing above all: start with what the writer already knows. And her grandfather knew one number better than his own birthday. The Carrick Holm light flashed three times every twenty seconds. Three. She shifted every letter back three places in the alphabet. N became K. L became I. W became T. Her pencil flew. KITTIWAKE HOME SUNDAY NIGHT. STEERS BY ME. NO RADIO. FIND THE KEEPER'S HOUR. Mira's skin prickled. A boat called the Kittiwake was coming home tonight, through the strait, with no working radio, steering by the light that was about to be switched off. She showed Desmond. He barely glanced at it. 'Your grandad's been on this rock alone too long,' he said, not unkindly, but not kindly either. 'No skipper navigates by eye these days. Every boat's got satellite plotters, radios, the lot. It's an old man's confusion, Mira. A ghost ship from one of his stories.' Then he checked his own watch, turned his wrist quickly away so she couldn't see the face, and went upstairs. Above them, the great clock ticked on. Find the keeper's hour.

5:13Inside the Clockwork

The clock room sat just below the lantern, a narrow chamber full of brass. Mira had always loved it. Iron weights hung on chains down a shaft through the tower. Toothed wheels turned against each other with slow, patient clicks. A long pendulum swung behind a glass door. The keeper's hour. What did that mean? Her grandfather had always called seven o'clock the keeper's hour, the time he climbed up each evening to wind the weights. Mira looked at the dial again, and saw it: beneath the numeral seven, a tiny brass plate she'd never noticed, held by a single screw. Behind it, scratched into the backing, was a rhyme in her grandfather's careful hand. When storm cuts the line and the old set is dumb, look under the weight where the low tides come. Mira ran down the spiral stairs to the base of the weight shaft. Wedged in a recess at the very bottom was an oilcloth bundle. Inside lay a battered handheld radio and a fresh battery. She clicked it on. Static roared. Then, through the hiss, a woman's voice: 'Carrick Holm, Carrick Holm, do you read me?'

6:14Rosa's Warning

It was Rosa Penhallow. Her voice came and went like a lamp in fog, but Mira caught the important parts. Her grandfather was safe in hospital on the mainland, with a broken ankle and a temper to match. And the Kittiwake was real. 'Small trawler, out of Saltwick,' Rosa crackled. 'Her radio packed in two days ago and her plotter with it. Skipper sent word by another boat that he's coming home the old way, on the Carrick Holm light. Nobody's told him it's going dark. I've been trying to reach him for hours.' 'When will he reach the strait?' Mira asked. 'Half eleven, near enough. Through the rocks on the north side.' Mira breathed out. Half past eleven. The light would burn until midnight. Tight, but enough. 'We'll be fine,' she said. 'The shutdown isn't until twelve.' There was a pause full of static. Then Rosa's voice came back, sharper. 'Mira, listen. Your grandad's been fretting since they brought him in. He keeps saying one thing over and over. He says, tell her the clock is wrong.' And then the signal dissolved into a roar of static, and Rosa was gone.

7:14The Engineer's Hands

The clock is wrong. Mira climbed back up the spiral stairs, her mind racing, and almost collided with Desmond coming down from the lantern. He had a heavy brass key in one hand. 'Lamp room's locked,' he said. 'Regulations. Nobody goes near the mechanism before shutdown.' He pocketed the key. As he brushed past, Mira noticed a dark smear across his shirt cuff, greenish-black and glossy. She knew that smear. It was clock oil, the same stuff her grandfather used on the wheels, the stuff that never quite washed out. Why would a lamp engineer have clock oil on his sleeve? 'Pack your bag,' Desmond said over his shoulder. 'The causeway's going under soon, and I'm not waiting.' Mira went to the window. Down below, the long stone path to the mainland was already narrowing, grey water licking in from both sides. Somewhere out in that darkness, a small boat with no radio was steering for a light. She turned back to the room and made her decision. The lighthouse was the safest place on the island, and she was staying in it. 'I'm not leaving,' she said. Desmond stopped on the stair. 'Then you'll be alone on this rock,' he said quietly, 'when it goes dark.'

8:22The Pendulum's Secret

Desmond went down to the kitchen, slamming the door. Mira stood alone in the clock room with her grandfather's logbook, turning pages until she found what she was half expecting. In the margin of an entry from last week, almost hidden among tide times, was another rhyme. When twelve calls an end that the keeper won't keep, the heart of the pendulum's hiding a key. It didn't quite rhyme, which was how she knew it was a clue. Her grandfather would never waste a bad rhyme on nothing. She opened the glass door, stilled the swinging pendulum with one careful hand, and felt along the heavy brass bob at its tip. A tiny catch clicked. The bob opened like a locket. Inside lay a small steel key stamped with two words: MANUAL LAMP. Engraved inside the lid were four more: TURN AS I TURN. A way to keep the light burning, even after the timer cut it. Mira let the pendulum swing free again, heart thudding. Then, above her head, the great clock gathered itself with a whirr of wheels and began to strike. Once. Twice. Eleven times. Eleven o'clock. One hour until the light died. And something about that sound was terribly, terribly wrong.

9:29Two Kinds of Time

Mira looked down at her grandfather's watch, buckled loosely round her wrist since the lifeboat left. She had not checked it once all evening. The hands said ten o'clock. For a moment she thought it had simply run slow. Then she remembered last night: her grandfather lifting his wrist at the six o'clock chime, nudging the crown, setting his watch by the tower as he had every evening for thirty-one years. That clock has never once been wrong. So the watch had matched the tower at six last night. And it was a good watch; it didn't lose an hour in a day. The watch hadn't changed. The tower clock had. Mira climbed onto the stool beside the dial and looked closely at the small square spindle where the hands were set. The brass was scratched bright and new, and smeared with greenish-black oil. Someone had pushed the clock forward one full hour. It wasn't eleven. It was ten. And the trip switch didn't care about real time. It would cut the light when this clock struck twelve, at eleven o'clock, half an hour before the Kittiwake reached the rocks.

10:27The Confession

Mira found Desmond in the kitchen, coat on, staring out at the flooding causeway. She held up her grandfather's watch. 'You moved the clock,' she said. For a long moment he said nothing. Then his shoulders dropped. 'The tide closes the path at midnight. Real midnight,' he said. 'The paperwork says I have to witness the shutdown. If I waited, I'd be stuck out here all night with the sea hammering at the walls. I can't do that. I won't.' His voice cracked on the last word. 'So I gave myself an hour. Nobody was meant to be hurt by it. The note was nonsense. It had to be.' 'It isn't nonsense,' Mira said. 'Rosa's been trying to reach that boat for hours. Put the clock back.' 'I can't. Wind the hands backwards with the trip set and it fires on the spot. The light goes out now instead of in an hour.' The handheld radio in Mira's pocket burst into life. Rosa's voice, frantic through the static. 'Mira, I've got the skipper's name from the harbour records. The Kittiwake's master is a Thomas Hale.'

11:22The Brother

All the colour left Desmond's face. 'Tom,' he whispered. 'That's my brother.' The words tumbled out of him then, fast and broken. Twelve years ago, Tom's first boat had gone onto the rocks in a winter gale. Desmond had stood on the shore, watching the lifeboat search, certain his brother was lost. Tom had lived. But afterwards the two of them had argued, bitterly, about the sea and about everything else, until they stopped speaking altogether. 'Last I heard, he'd sold up and moved inland,' Desmond said. 'He swore he'd never go back out.' 'Then he changed his mind,' said Mira. 'And he's trusting this light to bring him home.' Desmond looked at her, and for the first time since he'd arrived, he was not looking past anyone. He pulled the brass key from his pocket. 'The lamp room. What do you need?' Mira opened her hand to show him the little steel key. 'Grandad's,' she said. 'Manual lamp.' They raced up the stairs into the lantern, where the great lens turned in its blaze of light. Mira knelt by the control cabinet, searching for the keyhole, and her heart sank. Where the manual switch should have been, a fresh steel plate had been bolted over the panel, stamped with one word in red: DECOMMISSIONED.

12:30Midnight at Eleven

'I fitted that this morning,' Desmond groaned. 'Standard practice.' He tore open his toolbox and set to work on the bolts, hands shaking. Mira held the torch. One bolt. Two. The third was stubborn, and Desmond wrestled with it while the minutes slid away. Far below, they heard the tower clock begin its whirr. 'It's going to strike,' Mira said. The last bolt came free just as the first chime rang through the stone. The plate clattered to the floor. On the third chime, there was a heavy clunk from the timer, and the great lamp died. Darkness swallowed the lantern. Outside, the strait was black, endless, roaring. Mira found the keyhole by feel. Turn as I turn, her grandfather had written. The lens always turned clockwise. Mira pushed in the key and turned it, slowly, firmly, to the right. For one terrible second, nothing happened. Then a hum rose through the floor. A glow kindled at the heart of the lens, brightened, blazed, and the beam swung out across the water once more. Mira pressed her face to the glass. The light was back. But out in the storm, there was still no sign of the boat.

13:34The Kittiwake

They stood at the glass, staring into the storm. Waves exploded white over the northern rocks, again and again, and between them there was nothing but night. Her grandfather's watch ticked against her wrist. Twenty past eleven. Twenty-five past. Then Desmond made a sound she would never forget, half a laugh and half a sob. 'There,' he said. Far out in the strait, a tiny cluster of lights was rising and falling on the swell. Red and green. A boat. It came in slowly, carefully, exactly along the line the beam swept across the water, threading the narrow gap between the rocks the way thread finds the eye of a needle. The light swung round. The boat held its course. The light swung round again. And then the Kittiwake was through, out of the strait and into the calmer water beyond, turning for the harbour. The radio crackled. 'Carrick Holm,' Rosa said, and Mira could hear that she was smiling. 'She's past the rocks. I can see her from the harbour wall. Whatever you two did up there, well done.' Desmond sank down beside the lens and covered his face with his hands. Then he looked up at Mira. 'Will you help me put that clock right?'

14:38The Keeper's Hour

They stayed in the lantern until real midnight, when Rosa gave the word that the lighthouse authority had approved one last, proper shutdown. Mira turned the little steel key back, and the Carrick Holm light went quietly dark for the final time, an hour later than planned and exactly when it should. Then, with the trip switch disconnected, she and Desmond set the great clock back to the right time together. The sea covered the causeway all night. Neither of them minded as much as they'd expected. In the morning the stones came up shining, and they walked across side by side. Rosa was waiting at the harbour. So was a weathered man in a fisherman's jumper, standing very still beside a small trawler. Desmond stopped walking. Then the two brothers were moving toward each other, and Mira looked away to give them the moment. That afternoon at the hospital, she tried to give her grandfather back his watch. Elias shook his head and folded her fingers around it. 'Keep it,' he said. 'And always set it by something true.' Mira looked at the watch, ticking steady and honest in her hand, and knew that she already had.
