Dark clouds gathered above, casting shadows over the quiet estate. A chilling wind whispered secrets through the abandoned, ancient garden gate. Detective Moran arrived early, studying the eerie, lifeless scene awaiting him. The victim's body lay sprawled on the cold marble floor, blood pooled. Mystery hung heavy in the air, thick with secrets, lies, and betrayal. Footsteps echoed faintly in the empty halls, hinting at hidden intruders' presence. A single, cryptic note was placed carefully beside the silent corpse. Time seemed frozen; everyone inside seemed suspicious, yet no one confessed. The grand clock struck midnight, ominous sign of darkness, death, and despair. Moran knew this murder was just the beginning of a twisted game.
