Rain hammered the manor as midnight tolled across the moor.
Guests huddled near candelabras, whispers flickering like nervous moths there.
The host, Lord Whitcombe, raised champagne, smiling with brittle cheer.
Lightning revealed portraits glaring; past ancestors disapproved this merriment tonight.
Somewhere unseen, a clock wounded silence with relentless mechanical heartbeats.
Detective Arden arrived late, coat dripping, eyes counting exits carefully.
Servants presented oysters; thunder answered toasts with sardonic applause outside.
Then the generator coughed, failed, and everything inhaled blackness together.
Glass shattered; a woman screamed; footsteps tangled in carpeting confusion.
When lights returned, Lord Whitcombe lay skewered by decorative rapier.
Blood threaded across parquet, finding hungry seams like purposeful rivers.
Arden exhaled softly, noting everyone's expressions but nobody's alibis yet.
