In the 1970’s Hassel’s UK leading Publisher, Corgi, created a poster for marketing purposes that showcased a dramatic, thrilling and enticing set-up for the novels. The author was one of their top-selling writers. Even though the years have passed this is still one of the more loved posters created of the books. Today, Hassel’s novels are published by Orion in the English language, and have sold more than 15 million copies in this territory alone.
