There’s a scene in the movie Perfume: The Story of a Murderer (an adaptation of the novel by Patrick Suskind) in which a retiring perfumer discovers a fragrance created by a young olfactory genius. The scent transports him to a lush, mystical world in his mind. Surrounded by luscious flowers, a beautiful woman leans in and kisses him on the cheek and whispers in his ear. When he opens his eyes again, the change in him is visible – the scent has moved him, altered him in some way.
