Midnight settled over Blackthorn Manor. Rain hammered every shuttered window. Inside, twelve dinner guests waited. Their host remained conspicuously absent. Then thunder shook the chandeliers. A pistol cracked upstairs once. Everyone froze, counting silent heartbeats. Detective Vale reached the landing. Lord Blackthorn lay beside roses. Blood darkened his ivory waistcoat. One trembling hand clutched nothing. The locked door barred entry. Behind them, someone softly laughed.
