The maritime dread and ecclesiastical gloom aim for the chill of The Loney and the slow-burn claustrophobia of Dark Matter, but the plot never quite coheres. The instruction sequences feel mechanical, and the investigation stalls in meticulous sound jargon that saps urgency. There are lovely, briny images and a smart sense of place, yet the payoff is more whisper than revelation.
When out-of-work acoustics engineer Daniel Hargreaves is hired to survey the whispering gallery of St. Aurelius Cathedral in the salt-bitten town of Marrowhaven, he expects bad plaster and eccentric echoes. Instead, he records voices that answer questions no one asked and reply to names not spoken aloud. The caretaker, Sister Elowen, insists the gallery has always warned the town, but the warnings have grown hungrier since the last storm ripped the lead from the dome. As Daniel traces hairline cracks like veins through the stone, he finds old wax tablets tucked into the eaves, the confessions of people who should be long dead.
Each night the sound returns sharper: a child's skipping rhyme in Middle Cornish, a sailor's drowning prayer, his mother's lullaby sung from behind the organ pipes. A vellum ledger lists the gallery's "listeners", their names etched backward, matching disappearances filed in the town's shuttered archive. When the whispers become instructions—light the black candles, scatter salt in a circle, ring the bronze bell recovered from the wreck of the Luthien—Daniel must choose between sealing the dome and completing the ritual that feeds it. The decision draws the town into a single, trembling note that demands a sacrifice measured in silence.
