The lighthouse keeper never missed his morning bell before today. Detective Mara Quinn arrived precisely as fog lifted offshore slowly. The heavy iron door stood open against screaming wind relentlessly. Inside, the keeper lay sprawled beneath shattered lamp glass silently. Blood soaked his shirt, but seawater covered his boots completely. Someone had arranged his hands around a rusted key carefully. Mara noticed footprints leading nowhere near the cliff edge outside.
