The fog crept slowly over the abandoned lighthouse grounds tonight. Detective Sarah Chen stepped carefully onto the bloodstained wooden porch. Inside the old keeper's house, a dead body lay waiting. Marcus Webb had been dead for at least six hours. His cold glassy eyes stared upward toward the peeling ceiling. A silver letter opener protruded from his bloody chest wound. Sarah knelt beside the body without touching anything at all. There was no forced entry on any of the locks. The killer must have been someone Marcus knew quite well. Outside, the waves crashed against the rocks with relentless fury. Sarah noticed something very odd about the victim's left hand. His cold fingers clutched a torn piece of blue fabric. Somehow, the dying man had fought back against his death. Sarah pulled out her notebook and began writing her observations. This case would challenge everything that she thought she knew.
