Rain hammered St. Brigid's pier, drowning the lighthouse bell tonight. Detective Mara Quinn arrived late, coat heavy with saltwater spray. Fishermen watched silently, faces pale beneath yellow docklamps flickering overhead. A body lay curled inside the net shed, unseen until. Mara knelt close, noting rope burns and missing wedding ring. Captain Doyle swore the victim, Jonah Pike, feared nobody here. Yet Jonah's ledger vanished, along with keys to locker seven. From the fog, a harmonica moaned, then abruptly stopped cold. Mara followed that silence, tasting blood in the wind already. Somewhere nearby, someone held their breath, counting her footsteps carefully.
