Rain worried the mansion windows as midnight swallowed the valley. Inside, silver candlesticks trembled beside portraits with watchful, dustless eyes. Guests whispered politely, hiding grudges beneath champagne smiles and silk. Then the clock groaned once, and Lady Harrow screamed upstairs. We found Sir Alistair sprawled inside his locked study doorway. A chess king gleamed blackly in his stiffening, open hand. On the carpet, melted ice traced a stranger's careful route. Before dawn arrived, every soul there possessed motive, means, fear.
