Midnight rain tapped against battered windows as Detective Crane arrived at the secluded manor where sinister horrors ominously waited patiently. The grand chandelier flickered above polished marble floors revealing chaotic footprints leading toward a fresh crimson stain on powdered marble. A solitary gloved hand hovered above bloodless body sprawled unnaturally beneath shattered glass and a tiny broken delicate porcelain teacup. Detective Crane’s flashlight carved slender beams through darkness exposing scratched initials on oak door leading into abandoned east wing corridors. A distant grandfather clock tolled its gloomy hour as tension thickened and unseen watchers whispered cryptic warnings behind looming portraits.
