Inspector Cole arrived at Blackthorn Manor, where rain, candles, and frightened servants marked a terrible evening at the gate tonight. A body lay still on the marble floor, wearing a torn smile, a wedding ring, and no witness nearby tonight. Three guests claimed innocence, while a clock struck midnight and the telephone line suddenly died in the house that night. The butler whispered a name, then collapsed near the fireplace as rain filled the empty hall before pale dawn came.
