The grand clock struck midnight in the empty ballroom suddenly. A scream echoed through the halls of the ancient castle. Guests rushed towards the source of that terrible sound immediately. There they found Lady Eleanor lying dead on the floor. A dagger protruded from her chest with blood all around. The butler claimed he saw nothing unusual that fateful evening. Inspector Graves arrived promptly to investigate this shocking murder case.
