Rain silvered the harbor while Inspector Mara Voss counted five umbrellas and found only four still breathing beneath the pier. The dead man wore a wedding ring no local wife claimed and carried a ticket from midnight Mass dated yesterday. A candle burned inside the boathouse though every window was shuttered and the door had been nailed shut from outside. Mara lifted the lantern and saw blue ink spelling her name across his cuff in letters still wet that night. Somewhere beyond the fog a bell began counting thirteen strokes though the chapel clock had drowned last winter under ice.
