Rain lashed against the window. Thunder echoed through the mansion. Arthur lay on the rug. Dark blood stained his shirt. His cold eyes stared upward. A silver dagger gleamed nearby. Detective Vance lit a cigarette. He surveyed the quiet study. Every single window was locked. The killer was still inside. Footsteps creaked on the stairs. Vance reached for his gun.
