Which edition of《杜骗新书》contains modern parallels?
《江湖奇闻杜骗新书》(lit. Weird Things in the World: New Collection of Frauds) is written in a mixture of Classical and Vulgar Chinese. The Vulgar Chinese lately evolved into Modern Chinese in early 1920s (as the Government of ROC abolished all Classical Chinese textbooks in schools in 1922). Therefore, for a Chinese speaker above high school level, it is not a challenge reading this book. I guess that you can't find a Modern Chinese version because the book is written in a language that most Chinese people can loosely understand, if not completely, thus translation into Modern Chinese is not needed.
