Thegrand mansion loomed darkly under the stormy night sky. Rain pounded ceaselessly against the ancient windows outside. The clock struck midnight, echoing through the hollow halls. A shadowy figure moved silently through the corridors. A bloodcurdling scream shattered the oppressive silence suddenly. Police sirens wailed loudly in the distance approaching rapidly. Detective Harris arrived at the crime scene frantically. A lifeless body lay sprawled across the Persian rug. Blood pooled around the victim's lifeless form ominously.
