Detective Mara Quinn arrived at midnight to find the Victorian mansion silent, dark, and welcoming despite gathering storm clouds overhead. The body lay in the library beneath overturned shelves, surrounded by scattered letters, broken glass, and one polished brass candlestick. Everyone claimed they heard nothing, yet each guest suddenly remembered a different mysterious sound echoing through the long upstairs hallway. As Mara examined the victim's watch, its hands stopped at three fourteen, matching the time erased from the household ledger. Mara smiled grimly, closed her notebook, and whispered that the murderer had already made one fatal mistake tonight before sunrise.
