Rain polished the cobblestones outside Blackthorn Manor shortly before midnight. Inside, twelve guests waited beneath chandeliers, pretending not to shiver. Then the library clock chimed, and every candle suddenly vanished. Someone screamed near the conservatory, where Sir Alistair lay bleeding. His silver key glittered beside an unopened letter sealed tightly. Inspector Vale arrived smiling, although nobody had summoned her tonight. She studied the corpse, then noticed mud upon his cufflinks. The mud matched footprints leading upstairs toward the locked nursery. Behind its door, a child hummed the dead man's song.
