Rain stitched the harbor night, muffling footsteps on cobblestones below. Detective Mara Quinn watched lanterns tremble behind the customs shed. A whistle blew; the tide carried secrets toward black water. She followed a stray cat to the pier's locked gate. Someone had painted fresh numbers on splintered planks nearby tonight. Between crates, a body lay curled under tarpaulin, silent still. Mara lifted the edge, revealing frost on the man's lips. His pocket held a ticket stub, stamped for midnight passage. Footprints circled twice, then vanished where the rope ladder swung. From the fog, a violin note rose, sharp as accusation. She heard a cough above, and the lanterns suddenly died. In darkness, Mara whispered the victim's name, already knowing nothing.
