Just before we head home for the day i want to tell you about what promises to be a great documentary on BBC4 tonight on fragrance. I have just got back in the office from Guerlain's latest fragrance. Thierry Wasser (pictured), Guerlain's perfumer (or nose) talked us through the newest incarnation of the fragrance houses cult scent, Shalimar. Thierry and Guerlain will appear in a new documentary tonight. if you even have the remotest interest in where a scent comes from i urge you to watch it (I know I will).

Perfume tonight on BBC4 at 9pm
