Introduced by Richard West

This is the story of a remarkable young English nurse who made her home in a Saigon slum. Before the city fell to the communists she was told officially to leave South Vietnam. But she stayed. Her reason for not going was that her home was also home for street girls, drug addicts and waifs and strays picked off the streets who, without her, would have no one to turn to. This is not a story about the Vietnam war but the story of a young woman drawn to a suffering country by the plight of its suffering people.

Ludovic Kennedy talks to Liz Thomas about her reflections now on her time in Saigon.
