Rain stitched black threads across the harbor while Inspector Mara Voss counted footsteps echoing behind the locked boathouse door tonight. Inside lay councilman Vale beneath a tarp his signet ring missing and one clean candle burning beside his open hand. The tide had erased the gravel path yet crimson threads clung to rusted nails like careful accusations waiting for daylight. Mara photographed the flame then pocketed wax that smelled faintly of church incense expensive tobacco and panic disguised as cologne. A gull screamed from the rafters and somewhere beyond the fog an engine coughed once then decided to vanish quietly.
