The chilly autumn fog rolled over the silent harbor docks. Captain James found a bloody coat beside the empty warehouse. A faint golden light flickered inside the dark wooden cabin. He slowly opened the creaky door with his rusty lantern. The expensive leather chair sat turned toward the broken window. A tall wealthy man lay completely still on the floor. Fresh crimson blood pooled quietly beneath his fine silk shirt. The golden pocket watch in his hand kept ticking away. It pointed directly to midnight on this terrible stormy night. Nobody heard the lethal gunshot over the loud crashing waves. The mysterious killer had left no obvious clues or footprints. James carefully reached down to check the dead man’s pulse. Cold stiff fingers gripped a torn piece of ancient parchment. Strange cryptic letters were drawn hastily in thick dark ink. A shadow suddenly moved outside in the damp narrow alley.
