Cold November rain lashed against the cracked stained glass window. Inside the library, Arthur lay dead on the Persian rug. Red blood dripped slowly onto the expensive white wool fibers. Detective Vance stared closely at the strange silver letter opener. It was buried deeply within the screaming victim’s cold chest. A grandfather clock ticked loudly in the dark, dusty corner. Five frightened suspects stood silently near the roaring stone fireplace. Nobody dared to speak during this terrifying and tense moment. The killer was definitely still hiding inside this grand house.
