Rain hammered the windows of Blackmoor Manor while thunder rattled the ancient doors throughout the silent hours of that night. The detective arrived with a worn leather coat and a telegram clutched tightly in his shaking hand early that morning. The victim lay motionless in the library surrounded by overturned books and a single cold cup of tea beside him. Inspector Mara Quinn examined the frozen clock face and carefully noticed the missing key beneath the old scarred oak desk. Every guest in the hall claimed innocence yet each quietly hid jealous motives and buried resentful secrets behind polite smiles. Outside the storm intensified while inside the silence grew heavier around the body awaiting answers from everyone present that night. Then Mara whispered to the maid that the murder weapon would reveal a truth nobody dared speak aloud ever again.
