It was Mrs. Bonaparte who turned the general on to scent. Left to his own devices, Napoleon might have preferred the smell of gunpowder in the morning, but he was besotted by Josephine and perfume was – civilizing.

The coast was officially clear, the old royal perfume house of Houbigant returned to Paris, and the good times began to role once more.
