The rain hammered Inspector Vale's coat outside the locked library. Inside, Lord Ashcombe lay dead beside his overturned brandy glass. A single red rose rested neatly upon his pale chest. Vale noticed the grandfather clock had stopped at midnight exactly. The housekeeper whispered that nobody had entered since dinner ended. Yet wet footprints crossed the carpet toward the open window. Someone had clearly lied, and Vale intended discovering who tonight. Outside, thunder rolled across the dark hills beyond the estate.
