Rain hammered the greenhouse glass. Inspector Vale hated wet mornings. The body lay among orchids. Her name was Marguerite Ash. Someone had arranged her carefully. Hands folded, eyes politely closed. A white bloom crowned her. Vale crouched beside the corpse. Her wrist wore no watch. Pale skin showed its ghost. The killer took a souvenir. Sergeant Okoye cleared her throat. "The family waits inside, sir." Vale nodded without standing up. Water dripped from broken panes. Someone had smashed them inward. Glass lay beneath her body. That detail mattered a lot. The window broke before her. So she watched death arrive. Vale straightened, pocketing his gloves. "Let's go meet the liars."
