A Forty Minutes documentary film
Despite everything, the finishing school is alive and well and mainly to be found in Switzerland. Some 400 monuments to Swiss finishing skill exist in this Alpine paradise.
The most famous perhaps is the Institut Videmanette in Rougemont. For it was here that the future Princess of Wales completed her education. But high in esteem is the Institut Villa Pierrefeu that looks down on Montreux. Here some 24 young ladies are 'finished' at a cost to their parents of nearly E15,000 a year.
Finishing involves not only the learning of French, but also the mysteries of protocol, etiquette, floral art, precedence at table, haute cuisine, styles of furniture and decoration, couture, and all the skills necessary if a girl has the good fortune to 'marry someone who is someone'.
The finishing of three English girls, Sarah, Francesca and Natalie, is the subject of this documentary film.

The Bat, the Blossom and the Biologist with Donna Howell
There is in Arizona a bat that flies thousands of miles each spring to feed on the flowers of a plant that blooms only once in 25 years - and then dies. Last summer Q.E.D went to the Sonoran Desert in pursuit of this curious but intimate relationship - for it is a trading of food for sex: the bat gets the food and the flower gets pollinated in exchange.
For more than a decade, biologist Donna Howell has been unravelling how two such unlikely partners make the most of each other.
