Detective Marlowe arrived as the first pale light began to erode the night's oppressive, velvet darkness. The victim lay sprawled on the Persian rug, a single ruby brooch clutched in her stiffening hand. A half-empty glass of burgundy reflected the room's silent, glittering chandelier like a captured, frozen star. The clock on the mantel had stopped at precisely midnight, its pendulum hanging perfectly, accusingly, still.
