The old manor creaked under the weight of the gale. Wind howled like a heartbroken spirit through ancient trees. Inside, the vast library remained eerily quiet and disturbed. Sir Reginald lay slumped behind his vast oak desk. A silver letter opener glinted crimson in the lamplight glow. His lifeless eyes stared at the ornate, shadowed ceiling. Inspector Thorne surveyed the scene with methodical, sharp observation. This was not a natural end to his long life. Questions hung heavy in the air, unanswered and grim. A single, hastily extinguished cigar lay in the ashtray. The entire household waited, each person a potential suspect now. Fear and suspicion painted every pale, anxious face present.
