Barbara Winter was born in Western Australia in 1931 and graduated from the University of Western Australia with an Honours degree in modern languages. She won a scholarship that enabled her to study at the interpreters training centre attached to the University of Heidelberg, 1954-55, before she returned to teaching in Western Australia and Queensland. She gave up teaching in 1977 for domesticity, further study and a writing career. While carrying out research for the degrees of Master of Arts and Doctor of Philosophy, she discovered in the records of the secret service organisations a lot of interesting and largely unknown material that did not fit into either thesis. What is included in this book is only a small part of that which exists.
