Thick winter fog swallowed the crumbling stone walls of Blackwood. Inside the library, a single grandfather clock struck midnight slowly. Lord Reginald sat rigid in his favorite leather wingback chair. A crimson pool spilled silently onto his pristine white shirt. His cold, lifeless fingers still gripped the heavy silver key. The smelling salts nearby did not wake the dead nobleman. A heavy velvet curtain rustled softly in the freezing draft. Footsteps echoed down the empty corridor and then faded away.
