The grandfather clock struck midnight with hollow chimes. Rain lashed the stained glass windows of Thornwood Manor. Elena found the library door slightly ajar, creaking slow. Warm lamplight spilled across an overturned leather chair. A single crystal goblet lay shattered near the hearth. And then she saw the body, crumpled on the rug. His eyes were wide, a letter clutched in his hand. Above him, the portrait of his father stared down. Only the rain and silence answered her sharp gasp.
