Tamsin kept her hands in the warm pockets of her apron, though the air in the lantern room was never truly warm. The glass of the lamp caught the morning like a bowl catching sun; it held light and sent it out over the water as if the sea itself drank from it. Tamsin liked the way salt opened the lungs and the way gulls argued with one another in that high, thin voice that made the roof tiles shiver. She had lived at the lighthouse all her life, with a chair that creaked toward the window and a line of jars on the shelf, each jar full of things that had once been lost. Buttons that looked like tiny moons. A red marble that rolled like a planet when she nudged the jar. A ribbon with sun-faded stripes. People called the place the Lighthouse of Lost Things because, if you left something behind on the shore or the market or the pier, sometimes the light would blink and nudge it back to safety. That belief had lived in Tamsin like an old story: not questioned, only trusted. Grandfather Reyna, who kept the ledger and polished the brass with hands like weathered maps, used to say that the lamp didn't only show ships where to go. It kept watch for small griefs, too. 'A lost thing is a sort of packet of somebody's memory,' he would murmur, tapping the paper with a brown, knuckled finger. Tamsin liked to sort the jars by the way they smelled when she opened them: seaweed-sweet, lemon and oil, the faint iron of coins. She would open one lid, breathe, and think of whoever had held that thing last. Today she lifted a little fox of patched orange cloth from its jar and smoothed the seam along its tail. Its button eye had been sewn on wrong, and one ear drooped like a sleepy sail. The jar smelled faintly of milk and starch. Tamsin imagined a small boy in a woolen sweater slipping the fox under his arm on a morning when fog made the world round and soft. She fingered the fox's paw and heard the clockwork clicks in the wall—little honest sounds, like people breathing. Through the tall window she saw the town folded against the headland: low roofs, a bakery's smoke in a thin thread, the market flags limping in a friendly wind. A child, who visited sometimes to see the jars, often left a paper boat or a wooden soldier, and Tamsin learned names by the things: Nora's paper boats with blue crayon waves, Mr. Solla's missing thimble with a tiny dent. When the lighthouse bell tolled the hour, Tamsin put the fox gently back into the jar and set the lid with careful hands. Grandfather Reyna stood at the doorway, his coat smelling of coal and pencils. 'You'll be chief tonight,' he said, and his eyes were small and pleased. 'The fog will be thick, and the town will trust the light.' Tamsin felt a small lift in her chest. She had wanted to be trusted since she could remember. She also, in the way children often do, held a private sort of worry: she had never yet seen the lantern go dark, not in her memory. So the lamp was a thing that might always be there. She put on the brass goggles that sat on the shelf like a sleeping animal and climbed the narrow spiral to the lantern. When she reached the top, she set the fox's jar where the warm air from the lens could smell of sea. Outside, the tide folded itself in and out like a great slow hand.
