Cold morning rain washed over the quiet suburban neighborhood street. Detective Vance stepped carefully across the wet green lawn. Yellow police tape fluttered wildly in the sharp wind. Inside the brick house, tragedy waited silently for him. The broken body lay sprawled upon the hardwood floor. Broken glass surrounded the lifeless form like a jagged crown. A single silver pocket watch ticked loudly near the hand. Vance knelt down beside the victim to examine the wound. Deep crimson stains ruined the expensive wool of his sweater. This mysterious murder would test every skill he possessed today.
