Inevitable Crimes of Passion was inspired by a story Sarah's university friend told her. He was walking around the British Museum following a wonderful fragrance, which he traced to an elegant older woman. (Older than him that is; he was only 17.) Eventually he found the courage to ask her what she was wearing.
The idea that a fragrance might be so beautiful that it would challenge you to do something extraordinary started to grow, and eventually it took shape as the perfume of a Henry James novel. It's not one specific book, but as every one of his stories involves at least one young innocent rich American being seduced by one or more older, impoverished, charming shameless Europeans, it seemed to fit rather nicely with the original tale.
So this is the scent of being invited into the orangery, then to the parlour for cake and coffee, into the drawing room for cognac, then into the cellar never to be seen again. If we had to classify it, we'd say it's an outrageously seductive gourmand.
