This book, published in 1980 when the author was 65, astonished me. It won the Toronto Book Award in 1981, but the book or the author are not well-known. Weinman in her afterword calls it an "interior feminist espionage novel", & because the protagonist Shirley, alias Lola, travels from city to city to meet her mysterious lover who works for an international organisation called The Agency, I thought this would be Graham Greene-esque territory.
