The old manor stood silent under the dark, moonless sky. Detective Harding’s car crunched gravel, approaching the imposing estate entrance. A chill crept through the air, unsettling every known nerve. The grand oak doors swung open, revealing an empty hall. Shadows danced like ghosts across the polished antique wooden floor. A single crimson stain marred its pristine, dark surface. Harding felt a cold dread settle deep within his gut. This particular case already promised immense, dreadful complications ahead. No one expected such a brutal end tonight, not really. The silence screamed secrets only the dead could now tell.
