Many of Richler's novels were interconnected, taking place in the same narrative world. Jacob Hersh, a minor character in this novel, is the central character in St. Urbain's Horseman (1971); other Duddy characters are referenced in some of Richler's later works.
Aging in more-or-less real time, Duddy Kravitz makes brief, comic appearances in both St. Urbain's Horseman and Barney's Version (1997). As he ages, Duddy never loses his drive to make money, and in his final appearance in Barney's Version, Duddy is in his 60s and is financially successful.
