Thick fog wrapped around the old wooden docks as midnight chimed softly from the distant city church tower clock. Detective Vance pulled his collar up high against the bitter coastal wind and stepped over the slippery wet ropes. A single lantern flickered beside the dark barge, casting eerie, shifting shadows across the still and murky river water. Underneath the creaking deck boards lay the silent victim, dressed in a ruined velvet coat soaked in crimson blood. The dead man held a tiny silver key tightly inside his frozen right hand, concealing a dark, fatal secret. Vance knelt beside the cold corpse, carefully inspecting the mysterious wound that killed the prominent local banker so suddenly. No sound broke the heavy silence except for the distant cry of a lonely gull circling in the mist. "Someone wanted him dead tonight," Vance muttered softly to himself, noticing a faint scent of expensive French perfume nearby. This grim investigation was just beginning, and the dangerous killer was undoubtedly still watching from the surrounding dark night.
