The Princess and the President

In France, on Thursdays the most popular magazines here hit the newstands.
And today, the covers of the top ones (Paris-Match, Le Point, Le Nouvelle Observateur), share a same topic: the new book, to be on sale tomorrow, "La Princesse et le Président," written by Valéry Giscard d'Estang, former President of France.
It's been a week already since the whole French and English press started making assumptions on the subject of this novel which tells an impossible love story between Jacques-Henry Lambertye, President of France, and Lady Patricia, Princess of Cardiff, beautiful, blond and unhappily married to the Prince of Wales.
Hello? Does this ring a bell?
Well, as it happens, in the Nineties (more precisely in 1994), Lady Diana had a meeting with VGE (as he is known here), who had been President of France between 1974 and 1981. However, no-one could imagine that they actually had a thing going on! He was 65 by then and she a little over 30...
He wasn´t much of a heartbreaker, but quite a charmer... at least, that's what I'm being told.
Anyway, this is what's in everyone's conversation here in Paris.
VGE gave only one interview: to Le Point. There he says that it was Lady Diana's idea to create a love story with two characters just like them and that he, to honour her memory, decided to finally do so last year.
Of course, he denies a true romance but many believe he likes playing with the mistery and this, of course, will increase the sales of his book and maybe produce some sour relationships with the English.
Is it the outcome of the imagination of an old man?
Or really a love story with a tragic end?
I guess we'll never know for sure...
