Detective Maria Santos arrived at the Hargrove mansion precisely at midnight, when a blood moon hung low above the estate. Yellow police tape surrounded the historic property where the elderly industrialist Thomas Hargrove had taken his final, mysterious, violent breath. The body was discovered by the loyal housekeeper, a trembling woman named Eliza who had worked for thirty long years. She found him in his private study, slumped over the antique mahogany desk, surrounded by papers and spilled crimson wine. Detective Maria ducked under the bright yellow police tape, her worn leather shoes clicking against the marble steps leading inside. Her partner, James Chen, waited by the entrance, his ashen face pale under the harsh glare of police floodlights above. He nodded grimly toward the study, his silence speaking volumes about the gruesome scene that awaited her trained, careful eyes. The study reeked of sudden death and expensive scotch, a macabre combination that made her stomach turn with quiet disgust. The dead man's vacant eyes stared at nothing, his mouth frozen in a silent scream that would never be heard. His elegant silk bowtie had been tightened around his neck, cutting off air in what seemed a deliberate, painful execution. No signs of forced entry suggested someone known to him, someone who had watched him struggle and gasp for mercy. The wealthy victim's phone had been wiped completely clean, as if the killer wanted to erase all trace of communication. Detective Maria noticed a half-empty wine glass beside the body, a strange detail that would prove crucial to her investigation. The elderly housekeeper had heard absolutely nothing, she claimed, despite sleeping in a room just down the hall from murder. Thunder rumbled ominously in the dark distance as the first cold drops of rain began falling on the estate grounds.
