The heavy iron chandelier crashed onto the cold marble floor just as the clock struck midnight in the grand hall. Lord Harrington lay still amidst the jagged glass shards while a single red rose rested upon his lifeless, pale chest. Outside, the relentless rain lashed against the tall windows, masking the sound of retreating footsteps echoing through the dark woods. Detective Miller stepped inside, his sharp eyes scanning the shadows for any hint of a killer hiding in this gloom.
