A chilling fog settled over Tudor Manor this winter night. Inside, flickering candles cast dancing shadows across the ornate table. Detective Marlowe wiped coffee from his notebook with trembling hand. A shriek echoed down the corridor, freezing blood in veins. Mysterious footprints led from the study toward the library door. A single bloodstain glistened ominously beneath the antique chandelier’s reflection. Guests whispered frantic rumors about betrayal, greed, and family secrets. Marlowe’s eyes narrowed as moonlight revealed a discarded bloody dagger.
