Fog clung to Marrow Street. Detective Lysa arrived before dawn. A bell tolled, then stopped. Neighbors watched behind curtained windows. The townhouse door stood ajar. Inside, candles burned without flicker. A man lay beneath roses. His throat wore a ribbon. No blood stained the carpet. Only rainwater pooled near stairs. Lysa noted footprints, oddly absent. Someone had scrubbed the hallway. On the mantle, a clock. Its hands pointed at thirteen. A note rested under glass. It read: 'Tell nobody, Lysa'. She hadn't signed the register. Yet her name waited, inked.
