The old Victorian house stood in darkness as Detective Sarah Chen pulled her car into the gravel driveway tonight. Crimson bloodstains covered the marble floor where a wealthy businessman lay motionless with multiple stab wounds to his chest. The forensic team worked meticulously while Sarah examined a peculiar symbol drawn in blood near the victim's body. Neighbors reported hearing strange screams around midnight when the autumn storm had knocked out power throughout the entire neighborhood. Officer Martinez carefully bagged a bloodstained knife discovered underneath the antique couch in the dimly lit living room. A shattered portrait of the victim hung crookedly above the fireplace as if someone had deliberately knocked it down. The murder weapon matched a set of kitchen knives found neatly arranged in the recently polished stainless steel sink. Sarah noticed a halfempty wine glass beside the victim, suggesting he had been entertaining someone before his death. The victim's wife was reportedly away on business, leaving investigators wondering who else might have visited this evening. A cryptic note tucked into the victim's jacket pocket read "The truth cannot remain buried forever beneath lies."
