The sun is shining on the Trocadéro Garden - it is a blessing in Paris, even at the end of May. Behind you, the Eiffel Tower, before you, the Chaillot Palace, looking so modern. Suddenly, a woman approaches. She is carrying a huge bouquet of roses and heads towards the Seine with firm strides. When she brushes against you, you shiver with pleasure under the waves of rose so absolute that you but barely notice the trail of blackcurrant bud, lavender and musk.
