Martin, Diane and the students leave from Waterloo Station in London on the Eurostar to Paris.
They arrive at the beautiful old Gare du Nord in northern Paris.
At busy Republique Square, Martin is closer to his destiny. Rue Rampon and Irène Laureux are just around the corner.
Without Jeanne Moreau there would be no Irène Laureux.
Rue Rampon is the 11th arrondissement.
