The fog rolled over the dark harbor as Detective Mara Voss stepped onto the wet wooden dock at midnight alone. She carried only a flashlight and the sealed envelope containing the victim's final encrypted testimony regarding the major smuggling operation. A single yellow light flickered above the warehouse door while distant seagulls cried out into the pitch black night sky. Blood stained the concrete steps leading down to the water where the body had been discovered by the fisherman earlier. Mara knelt beside the corpse and noticed the peculiar silver locket clutched tightly in the dead man's rigid frozen hand. Someone had murdered him here but left no obvious clues except for this mysterious piece of jewelry gleaming dully now. The envelope in her pocket suddenly felt heavy with dangerous secrets that would unravel the entire criminal organization before dawn. A shadow moved behind the rusted shipping containers as Mara stood up slowly and reached for her service weapon now.
