The rain lashed against the darkened windows of Blackwood Manor. Inspector Morley stepped across the threshold, his leather shoes squeaking. Blood had dried upon the Persian carpet near the fireplace. Lady Blackwood lay sprawled, her blue eyes staring straight upward. A silver letter opener jutted from her pale bloody chest. The butler wrung his hands near the mahogany grand piano. "Nobody entered this room after we had finished dinner tonight." Morley studied the broken latch on the French window closely. Thunder rolled across the heath as the great storm worsened. Every guest in this house had strong motive for murder.
