A bitter autumn wind rattled the broken greenhouse glass pane. Cold rain washed away the fresh blood on her shoes. Lord Reginald lay silent beside the smashed flowerpot of orchids. The silver clock on the mantelpiece chimed exactly three. No one heard the desperate scream cut short tonight. A yellow silk scarf lay tightly wrapped around his neck. Footsteps echoed sharply down the dark, empty marble hallway. The killer slipped quietly through the unlocked iron garden gate. Inspector Miller stared glumly at the ruin of his weekend. Too many secrets remained buried within this old stone manor.
