An oppressive, grey fog clung to the silent, deserted London docks early that November morning, obscuring all the visible details. Detective Alistair Finch pulled his worn wool coat tighter against the relentless damp chill as he walked very slowly forward. His flashlight beam cut through the thick gloom, suddenly illuminating a pale, lifeless hand upon the cold, wet, slippery cobblestones. The body of a young woman lay completely sprawled near the dark, lapping water, her eyes staring sightlessly upward now. A single, silver pendant gleamed at her pale throat, oddly, seemingly untouched by the surrounding grime and general filth everywhere. Finch knelt beside her, his breath forming quick, white clouds in the very cold, still air around them both now. There were no obvious wounds, no visible blood at all, just this terrible, silent stillness within the thickening, oppressive fog.
