Rain battered Blackthorn Hall's windows. Inside, twelve guests awaited dinner. Their host remained conspicuously absent. The grandfather clock struck thirteen. Nobody laughed at its mistake. Then somebody screamed upstairs twice. Inspector Vale abandoned his sherry. He reached the locked study. Blood seeped beneath its door. The butler produced three keys. Only the smallest fitted properly. Sir Edmund lay facing heaven. His waistcoat bloomed with crimson. His fingers gripped a photograph. Every guest appeared within it. One face had been removed. Vale examined the empty space. Five words marked the back. “You were warned, Inspector Vale.” The handwriting was his own.
