I placed my new novel, 'The Book of Lost Fragrances', in Paris, knowing it would be a challenge. But the book belonged in the city that is one of the greatest perfume capitals of the world and has been since for more than three centuries.
I work on one book at a time. And yes, I am immersed. Six days a week for four to six hours a day. In between books, I stop writing for as much as two to three months, but during that time, I do research and think, plot and plan the book.
