Hasluck then travelled to Albania where she undertook anthropological research in Macedonia and made her home in Elbasan for 13 years, becoming a legend among the Albanians and publishing numerous articles, including the first English-Albanian grammar and reader. Due to her intelligence work in World War I, she was forced to leave Albania for Athens when the Italians annexed the country in 1939. While in Albania, Hasluck is said to have been romantically involved with Albanian scholar and politician Lef Nosi, to whom she left her rich personal library.
