The fire that killed her father took Iris’s sight — but sharpened the one gift that built the family perfume house: a nose that never forgets. Five years later, at a gala honoring her uncle’s takeover of the company, she smells it again. The cologne worn by the man who locked the study door that night. Blind, underestimated, and legally erased from the will, Iris rebuilds her father’s master formulas from memory and launches a rival house designed to lure the arsonist into the open. Every fragrance she releases is a message: I know it was you. And I’m getting closer.
