The old mansion stood silent beneath the heavy November rain tonight while detectives prepared their careful and thorough examination methods. Inside the grand foyer, the broken body lay cold upon the polished marble floors while shadows stretched across the room. A single crimson knife rested near the lifeless, outstretched right hand while guests whispered dark rumors inside the dusty parlor. The lead investigator arrived wearing his oldest, most reliable gray overcoat today while rain soaked through his heavy boots completely. He immediately began searching every corner of that dimly lit upstairs hallway while taking careful notes upon his small notebook. Hidden within a velvet curtain, a crucial photograph waited patiently for discovery while detectives questioned every person inside the house. The truth about the murder would finally emerge from these silent walls when investigators matched fingerprints upon the broken glass.
