 As his career lengthened, both Greene and his readers found the distinction between entertainments and novels increasingly problematic.The last book Greene termed an entertainment was "Our Man in Havana" in 1958.When "Travels with My Aunt" was published eleven years later, many reviewers noted that Greene had designated it a novel, even though, as a work decidedly comic in tone, it appeared closer to his last two entertainments, "Loser Takes All" and "Our Man in Havana", than to any of the novels.
