The Humming Light of Seafare Cove

Tessa Quill liked to draw the coastline as if it were a living thing. On the table by the lighthouse window she spread her notebook, anchoring the corners with smooth shells so the sea breeze couldn’t flip the pages. Far below, waves combed the shingle and left ribbons of foam. Gulls argued over a crab shell near the tide line. The lantern room hummed softly above her head, the great glass lens turning with patient grace. It smelled of salt and machine oil and a little like lemons, because Mr. Hollis rubbed the brass with lemon paste when the salt crusted on it.

“Lines straight, little mapmaker,” Mr. Hollis called from the spiral stairs. His voice carried up with the tap of his cane. He was tall and slightly bent, with a face like a wrinkled chart and eyes that could still spot a storm before the clouds got their boots on.

“I’m drawing the bight beyond Gull’s Tooth,” Tessa said, biting her pencil. “When the tide’s low, there’s a ridge here. See?” She sketched a dotted line. The paper swished under her hand.

Mr. Hollis came to the table and leaned over her shoulder. “A fair eye. That saves fools from grounding their boats.” He tapped the sill. “Listen.”

Tessa listened. Beyond the steady hush of waves and the faint whirr of the clockwork, another sound threaded the air. It was a thin note, like a glass singing. She felt it in her teeth.

“What’s that?” she whispered.

“Glass can speak when it’s not happy,” Mr. Hollis said, half joking, half not. He rubbed a hand over the lens housing as if calming a horse. The huge rings of glass, stacked like a shining onion, caught the late sun and cut it into slivers. “Could be the wind. Could be a seam we need to mind.”

Tessa reached out. The brass was cool; the glass was warmer, as if it stored light. She loved the way the lens took a small flame and made a stripe that could slice fog. She loved the lighthouse’s bones—the spiral stairs, the officious plaques, the smell of old raincoats drying on pegs.

“Your dad’s waiting at the bait shop by sundown,” Mr. Hollis said. “Don’t miss your ferry sandwich.”

“I won’t.” Tessa tucked a curl behind her ear. The curl sprang out again stubbornly. She lifted the notebook, blew away pencil crumbs, and closed it. When she looked down the cliff, a black bird floated near the rocks, wings tucked, body slick as ink. It dove and popped up with a strand of green weed wrapped around its beak. It shook, splattered, and looked up as if it could see her.

“Hi, you,” Tessa said to the window. The bird flapped once, then ducked beneath. The tower hummed again, just once, and the hair on Tessa’s arms lifted.

Evening pulled a gray shawl over Seafare Cove. By the time Tessa climbed the last steps with Mr. Hollis to check the lantern, the air tasted colder. The glass made a soft creak like a giant stretching. A moth batted at a pane and slid away. The wick inside the lamp burned steady, a bead of steady gold.

Mr. Hollis ran careful fingers around the metal bands. “Tell me if you ever see a chip,” he said. “Every piece helps the whole. Take one away, and the beam frays.”

Tessa peered through. Through the facets, the horizon broke into a stack of tiny worlds. She reached into her pocket and felt the round weight of her mother’s compass—a small brass disk with a lid that clicked shut like a coin purse. It had a nick on one edge from a slip years ago. The needle trembled even while the lighthouse stood still. It always did that near the lantern, and Tessa thought the compass might be excited.

Something flickered then. Tessa frowned. In the lower ring of glass, a glimmer seemed absent, the way a smile looks different when a tooth is missing. She blinked and the glass rang—one clear ping like a note plucked on a crystal string. Mr. Hollis stiffened.

“Did you hear—” Tessa began.

He lifted a finger. They both looked at the service ladder, a narrow thing fixed along the wall toward a trapdoor. A smear of shadow moved on the far side, then stilled. The sound of the sea swelled, then hushed, as if it had leaned in too.

Tessa’s heart jabbed. “Someone’s here.”

Mr. Hollis strode to the ladder and swung up with speed that did not match his cane. He pushed open the trapdoor and peered out onto the dew-slicked walk encircling the lantern. Wind touched his cap. Nobody. He crouched, ran a hand along the sill, and brought it back with a tiny slice of something on his fingertip. Glass. He frowned.

“Inside,” he said, voice tight. “We’ll lock up and look at first light.”

On the floor, near a bolt, Tessa saw a chalk mark. It was faint as dust, shaped like a little anchor with a crooked shank. She crouched too, hollow with curiosity. When she looked again, the mark seemed to have melted into the stones, grain by grain, as if it was part of them all along.
