The Diggelmann collected works in six volumes. The novel "The Interrogation of Harry Wind" - the third volume of the six-volume collected works published by edition 8 - suddenly made the author well-known beyond the country's borders in 1962. The style, a sparse and strongly documentary realism, was new. The novel brought Walter Matthias Diggelmann his first major success in 1962 and made him suddenly known beyond the country's borders. The topic of the book was not only provocative and highly relevant; the style, a sparse and strongly documentary realism, was also new and evidently resonated with the tastes of the time. As was typical for Diggelmann, the material for this novel stemmed from his very personal experience. As a copywriter in Rudolf Farner's advertising agency, he had learned about the then brand-new methods of political public relations.
