The old Victorian mansion stood silent under the pouring rain as thunder rumbled through the dark stormy night sky outside. Inside the grand hallway a lifeless body lay sprawled across the marble floor with a knife protruding from its chest. Blood slowly pooled around the victim creating a dark stain that contrasted sharply against the otherwise pristine white tiles nearby. Detective Harris arrived promptly at the crime scene after receiving an urgent telephone call from the terrified household staff members. He examined the surroundings carefully noting every possible detail that might provide clues about the identity of the mysterious killer. The storm continued raging furiously outside while questions filled the air regarding who committed this heinous crime in such isolation.
