The rain fell heavily on the old mansion’s windows. A body lay sprawled across the library’s Persian rug. Every guest’s alibi seemed weaker the more they talked. The butler’s hands trembled as he passed the tea. Flickering candlelight cast eerie shadows on the walls. Whispers spread like wildfire through the grand hallway. A locked study held secrets nobody dared mention. The clock struck midnight, yet no one slept soundly. Strange footprints led from the balcony to nowhere. Your name was the last scribbled in the victim’s diary.
