Heller is widely regarded as one of the best post-World War II satirists, remembered mostly for Catch 22.
Heller wrote an additional four novels (Something Happened, Good as Gold, God Knows, Picture This). One of his later novels, Closing Time (1994) revisited many of the characters who had been featured in Catch-22 as they adjusted to post-war New York. All of the novels sold respectably well, but could not duplicate the success of the debut. Told by an interviewer that he had never produced anything else as good as Catch-22, Heller famously responded, "Who has?".
