Midnight fog swallowed Brindle Street. Detective Mara Quinn arrived silently. Sirens wailed beyond shuttered windows. Lantern light trembled on cobblestones. Captain Ives pointed upstairs grimly. A door stood slightly ajar. Inside, perfume mixed with iron. Lady Harlow lay perfectly still. Her pearls were snapped, scattered. A note rested under candlestick. Mara read: Trust nobody here. Outside, footsteps fled into fog.
