The storm began at midnight when the chandelier crashed, glass shards glistening like blood on Persian carpets in the silent mansion. By dawn, Lady Evelyn’s throat was cold marble, her emerald eyes dulled by the weight of a silver dagger protruding between her ribs. Dr. Hartwell arrived through rain and rumors, coat darkened by thunder and face sharpened by the scent of death and secrets in the air. Mrs. Thorne, the maid, whispered in corners, her trembling hands gripping a bloodied letter left at the fireplace’s crackling hearth. The grandfather clock froze at half-past three, its ticking silenced as if guilt had stolen its pulse in the candlelit gloom. Captain Blackwood stood in the doorway, a whiskey glass held like a trophy, lips curled with secrets the rain couldn’t wash away. In the library, a shattered teacup dripped on yellowed ledgers, hiding a name inked in haste by someone who knew their crime. Miss Harlowe, the pianist, played funeral dirges too loud for comfort, ignoring questions about her midnight visit to the study. The butler’s alibi hung on a cracked pocket watch, its hands frozen at an hour no witness could confirm or deny. Thunder shook the stained-glass tower where shadows danced like accusing ghosts, revealing too much in flashes of blue light.
