Huey and Dalian go to a local shop to buy some sweet buns, where they bump into a woman as she is being chased. She is revealed to be Fiona, a talented Perfumer who is able to tell someone's emotions just by their smell. Fiona makes perfume for a cosmetics company in London called Famenias, best known for their perfume. After meeting with Fiona's father, the president of the company, he tells them of an ancient text his grandfather found that gave him the idea to sell perfume. Believing that the book Fiona now possesses is a Phantom Book, Huey and Dalian visit Fiona's estate to investigate.
