Walking quietly around the cobbled streets of Riga’s old town, Zanna explains to a group of tourists about the particularities of the Art Nouveau style that adorn many of the facades of the buildings in Latvia’s capital city. For many years now, this 71-year-old woman has worked as a tour guide for Russian visitors in the country where she was born after her father, who was born in Russia, was sent to the Baltic shore to fight the Germans in the Second World War. Zanna, born in 1941, never knew her father. He set off for the war one day and never made it back.
