The grandfather clock in the hall chimed eleven, its hollow tones echoing through the silent, moonlit manor. Guests had departed, leaving only the scent of wilting lilies and the ghost of cheap champagne. Margaret was discovered by the butler, her silk gown pooled on the cold hearthstone like spilled wine. A single pearl earring lay on the rug, its partner missing, a clue to her final struggle. The poker from the fireplace was displaced, a thin film of ash marking a brutal trajectory. Inspector Langley arrived, his weary eyes cataloging the scene with practiced, mournful precision. He noted the untouched brandy glass, the open window letting in a damp, conspiratorial breeze. The family portrait on the wall smiled down, its subjects oblivious to the crime below them. William, her husband, claimed he heard nothing, his study door thick as a vault of secrets. Each servant had a story, each a alibi as polished and fragile as the finest porcelain. The list of heirs was short, their motives long, stretching back through years of bitter resentment. Langley circled the room, a silent predator hunting for the smallest, most revealing inconsistency. He paused by the clock, hearing not its tick, but the heartbeat of a killer nearby.
