Midnight pressed against the cliffs; Detective Mara Venn climbed upward, while fog swallowed every lantern below the silent harbor town. The keeper lay near flame, one hand curled around a brass key that every guest denied knowing existed at all. Outside, the parlor windows gaped, and moonlight laid bright knives across the rug where muddy footprints ended abruptly without warning. A violinist, a widow, a priest, and a smuggler played cards beneath the portrait of the drowned founder in silence. Mara pocketed the key, heard the tower door sigh shut, and understood the killer had never left the island tonight.
