The heavy rain lashed against the large windowpane while the old clock ticked loudly in the dark, cold, quiet hall. Detective Miller stepped into the large room, his eyes scanning the floor for any sign of the killer standing nearby. The cold body lay motionless on the carpet, surrounded by shards of glass and a single, dark red rose petal. The victim was a wealthy man known for his charity work and his vast collection of rare and shining gems. Miller walked slowly towards the corpse, wondering who could commit such a heinous crime in this quiet, peaceful town tonight. He saw a small silver locket clutched tightly in the dead man's cold hand, gleaming under the pale street light. Someone knocked on the heavy front door, echoing loudly through the silent house and startling the detective from his thoughts.
