Midnight draped Blackthorn Manor in silence. Rain tapped sharply against leaded windows. Detective Vale arrived without an umbrella. The butler opened doors reluctantly. “Someone murdered Lady Blackthorn,” whispered Graves. Vale removed soaked gloves, studying him. “Where is the body?” Vale asked. “Inside the library,” Graves answered quickly. A clock chimed thirteen mournful notes. Vale noticed blood beneath Graves’s cuff.
