"As entertaining as it is original, this is the story to enjoy like a chocolate with a surprise centre" -Marie France

"Impossible to resist" -L'Express

Dining alone in an elegant Parisian brasserie, accountant Daniel Mercier can hardly believe his eyes when French President François Mitterrand sits down to eat at the table next to him. Once the presidential party has gone, Daniel discovers that Mitterrand's black felt hat has been left behind. After a few moments' soul-searching, Daniel decides to keep the hat as a souvenir of an extraordinary evening. It's a perfect fit, and as he leaves the restaurant Daniel begins to feel somehow . . . different.

Has Daniel unwittingly discovered the secret of supreme power? Over the course of the next 2 years the iconic item of headgear plays with the lives of the men and women who wear it, bringing them success that had previously eluded them. As it makes its way from head to head, the wearers find themselves acting with more confidence, decisiveness, authority and panache--just like the original wearer. Some, like Daniel, attribute their new luck to the hat itself, while some are unaware of its magical effects. All, however, find themselves changed by their time spent wearing the president's hat.

Shot through with a delicious, wicked sense of humour, this delightfully quirky novel is a vivid re-creation of 1980s Paris, and an enchanting exploration of life's possibilities.
