Rain hammered the harbor as Detective Mara Voss arrived alone. The ferry light burned white above the blackened water tonight. A body waited beneath the pier, folded like wet canvas. No wallet, no phone, only black tar inside his mouth. Mara noticed bright salt glittering on cuffs far too expensive. The victim wore her missing partner's silver academy ring tonight. Across the bay, a chapel bell began counting thirteen slowly. Then the radio whispered her name and went dead again.
