The rain soaked the cobblestones outside the manor. A single lamp flickered inside the study window. Lord Ashworth lay slumped across his mahogany desk. His hand still gripped a half-finished glass of wine. The clock on the mantle stopped ticking at nine. A faint scent of almonds hung in the air. The door was locked from the inside, they found. No one heard the scream over the crashing storm.
