The old mansion stood silent against the dark stormy night. Detective Sarah Mills stepped out of her car and paused. Rain soaked her coat as she approached the front door. A uniformed officer waited on the porch with grim eyes. He said the body was found in the study upstairs. She nodded once and followed him through the grand hallway. Portraits of wealthy ancestors lined the walls in silent judgment. The smell of old wood and something metallic filled everything. Upstairs, a door hung open, spilling pale light into darkness. She stepped inside and saw what no one should see. Victor Ashworth lay crumpled beside his desk in dark blood. His cold hand still clutched a torn photograph of someone. The window behind him was shattered open to the storm. Sarah knelt down and studied the wound across his throat. This was no accident and it was no simple robbery. Someone in this house had wanted Victor Ashworth permanently silenced.
