Rain hammered the glass roof of Blackwood Hall while dinner guests admired silver candlesticks and ignored the locked library door. At midnight the butler found Lord Vale collapsed beside his desk with a crimson stain spreading across the emerald carpet. Every guest swore they had been dancing when the lights failed yet muddy footprints circled the fireplace like an accusation. Inspector Marlowe arrived before dawn noted the missing key and asked why the victim still tightly clutched a white gardenia. Outside thunder erased the gravel paths and somewhere beneath the east terrace a telephone rang twice then went suddenly silent.
