At the height of her popularity, Helen MacInnes was known as the “queen of international espionage fiction.” Although her novels contain much less sex and violence than others of the genre, they are highly suspenseful. In addition, they are based on an appreciation of justice, freedom, and individual dignity. Perhaps the most characteristic element of MacInnes’s novels is their settings, which are invariably beautiful and of historic interest. The capital cities of Europe and its many forests, lakes, castles, and opera houses are described in such detail that the novels may be enjoyed as travel books. Brittany, Salzburg, Málaga, Venice, and Rome come alive for the reader. MacInnes’s love for these and other spots of the world, as well as her appreciation of democratic values, illuminates and enhances her novels.
