I am in Switzerland to investigate the sex trade in this liberal country, famous for its perfectionism, precision and punctuality. It is also home to a number of migrant populations, and often referred to as Geneva’s “global village.” Rue Sismondi, in the heart of the Pâquis district of Geneva, is known for prostitution, drugs and gang violence. The streets are empty except for a dozen women and their pimps.

and the rain is coming down in sheets and bouncing off the pavements.
