The clock struck midnight as the storm raged, casting eerie shadows across the dimly lit, opulent Victorian mansion. A chilling scream pierced the air, echoing through the grand hallways, sending shivers down the spines of all present. Detective Harper arrived promptly, his trench coat soaked, eyes scanning the room for any sign of foul play. The guests, dressed in their finest attire, whispered nervously, their faces pale with a mix of fear and curiosity. A shattered vase lay on the floor, its pieces scattered like a puzzle waiting to be solved. The butler, trembling, pointed towards the library where the door stood ominously ajar, creaking slightly. Harper approached cautiously, his heart pounding, as he pushed the door open to reveal the gruesome scene. A body lay sprawled on the Persian rug, blood pooling beneath, a dagger protruding from the chest. The victim, a wealthy businessman, was known for his ruthless dealings and numerous enemies in high places. Harper knelt beside the corpse, examining the wound, while the guests gathered at the doorway, gasping in horror.
