The dark night enveloped the quiet English countryside completely now. Suddenly a desperate scream echoed through the ancient stone manor. Guests hurried to the noise and found the dead victim. Her body lay sprawled across the oriental living room rug. Blood trickled slowly from a wound in her pale neck. The detective soon arrived to unravel this mysterious fatal puzzle.
