The grand old house stood silent beneath a pale and watchful moon last night. A single gunshot shattered the peaceful calm of the sleeping countryside. We found his body in the study, a single wound to his chest. The family all claim they heard nothing, which is frankly impossible. Every one of them had a motive, and not one alibi. I suspect this case will be far more complex than it appears.
