The rain hammered the windows of Blackwood Manor all night. Detective Eleanor Vance arrived before dawn, coat soaked, eyes sharp. A body lay sprawled beside the fireplace, unmistakably quite dead. Sir Reginald Blackwood clutched a silver letter opener in hand. Blood pooled darkly beneath him, staining the expensive Persian rug. Five guests watched silently from the doorway, faces pale, trembling. Someone here was lying, and Eleanor would uncover the truth. The grandfather clock struck six, echoing through the silent house. Eleanor asked who discovered him, studying each nervous face carefully. The housekeeper stepped forward, wringing her apron, voice barely audible. "I found him at five, cold as winter stone, madam." Behind her, something metallic clattered onto the marble kitchen floor. Every head turned sharply toward the darkened doorway beyond her. A shadow vanished quickly before anyone could utter a word.
