12-year-old orphan, Bunny Spark, and her twin brother, Beau, live above their family's run-down department store in the grim, industrial town of Grayton. A strange perfumer who calls himself the Nose comes to the store to make and sell perfume. Thousands of people come to buy the young man's unusual perfume, which genuinely seems to live up to its promise of making adults as happy as children, but when the twins' extremely happy younger cousin is drained of all happiness, they begin to suspect that something fishy is going on. SPARK'S AND CAMPBELL'S EMPORIUM OF INTERESTING GOODS PRESENTS: THE NOSE AND HIS PERFUME is a not so serious middle grade fantasy.
