The grand old house stood silent beneath a pale and watchful autumn moon. A single light burned within the study's high, narrow window. Inside, a man was dead, seated calmly behind his vast oak desk. A dark crimson stain spread slowly across his crisp white shirtfront. No weapon was visible in the meticulously ordered, book-lined room. His cold hands rested upon a sealed letter addressed to Inspector Hayes. The clock upon the mantelpiece ticked steadily, counting the empty seconds. Outside, a lone figure watched the house from the shadowy garden. They turned up their coat collar against the chill night air. Soon, the silence would be broken by the approaching sirens' wail.
