Rain silvered the manor windows. Inside, clocks drowned midnight's arrival. Detective Mara Vale entered quietly. The butler blocked her path. His gloves smelled of almonds. Behind him, guests whispered prayers. Lord Ashcombe lay beneath roses. A letter pinned his throat. Wax sealed its crimson mouth. Mara read the single line. Everyone here has killed tonight. Thunder answered from the staircase.
