Rain stitched the harbor lights into trembling silver threads tonight. Detective Mara Vale watched gulls coil above the boarded pier. The call had dragged her from coffee and unfinished sleep. At Warehouse Twelve, a door hung crooked, breathing salted rot. Inside, footprints smeared rainbow oil across concrete like bruised constellations. A generator coughed, then died, letting shadows settle like ash. Mara lifted caution tape, tasting coppery air that remembered screams. The body lay facedown near crates stenciled with vanished names. A single glove pointed seaward, accusing tides of complicity tonight. Her partner arrived late, humming apologies nobody could truly hear. He flipped the ID card, eyebrows tightening at its photograph. The victim funded charities, and enemies disguised themselves as beneficiaries. Some crates were empty, others groaned softly, padlocks pretending diligence. Rain thickened, drumming clues into puddles that refused translation tonight. Mara photographed everything, but the scene photographed her instead back. A whistle blew distant, precise, like someone counting down options. She pocketed the glove, feeling threads rasp secrets against skin. Somewhere above, a camera blinked, swallowing evidence with polite hunger. The harbor clock tolled four, sounding tender, almost apologizing softly. Mara whispered names, and the dark answered with one back.
