Rain hammered the slate roof. Margot Ellery checked her watch. The dinner guests were late. Candles burned low in silver. She poured herself more wine. Somewhere a floorboard creaked twice. "Hello?" she called into darkness. No one answered her question. The front door stood open. Wet footprints crossed the marble. They led toward the study. Margot followed them, heart pounding. The study door was locked. She knocked, then tried harder. A thin red line appeared. It seeped beneath the door. Margot dropped her crystal glass. Glass shattered across cold stone. She ran for the telephone. The line had gone dead. Behind her, the lock turned.
