The mansion stood in darkness. Rain pounded against the windows. Lightning flashed across the sky. Thunder shook the old walls. Lady Pemberton screamed once loudly. Her guests rushed upstairs quickly. The study door hung open. Blood pooled on Persian rugs. The butler called for help. Everyone gathered in shocked silence. Sir Pemberton lay there motionless. A letter opener protruded deeply. "Nobody leaves," the butler commanded. The storm raged on outside. Nine suspects waited nervously together. Each harbored their own secrets. The grandfather clock struck midnight. Death had visited Pemberton Manor.
