Ariadne's thread

This is based on the true story of a young Greek nursing student, Elena Avgoulas, who makes a daring escape from her occupied Greek island of Chios and travels to Palestine where she enrols in the British army as a nurse. She is posted to a Base Hospital in Alexandria, Egypt where she tends the wounded from the war that is being fought in the North African desert and experiences the life of cosmopolitan Cairo as the Axis armies advance to the very gates of the city.
She meets and falls in love with a young Scottish Army officer who is serving with the Long Range Desert Group. As the course of the war changes in favour of the Allies, the two lovers are separated; he is posted to Britain to serve with the Special Operations Executive and she, newly promoted, serves in the invasion of Sicily with a Casualty Clearing Station.
Her nursing takes her through Italy and across the Rhine into Germany.
As the war ends, out of touch with her earlier life, she seems destined for a comfortable future in England as the wife of a surgeon but the sudden death of her mother draws her back to Greece as the Civil War begins and suddenly the unravelled threads of her past are brought together.
