At midnight, the caretaker found Lady Vale beneath the conservatory skylight, her white gloves folded neatly beside the broken glass. Rain soaked the orchids, yet her evening gown remained dry, and the brass key in her palm felt strangely warm. Inspector Marsh arrived before dawn and noticed three muddy footprints entering the room, though none led back toward the garden. Above the body, someone had written a single word on the fogged glass, but the first sunlight erased it completely.
