The book used multiple stylistic techniques. At various points, Johnson quotes from
Summa de arithmetica by
Luca Pacioli, the first work to discuss the system of double-entry bookkeeping. There are also multiple "reckonings", in which are printed the records of Christie's debits and credits in the form of pages written up from an account book, with the final page of the novel having the words: "Account Closed" scrawled on the bottom.
Metafictional elements Johnson scatters many
metafictional elements throughout the novel, often for comedic effect. Characters frequently mention in passing that they know that they are works of fiction, such as when Malry's mother says to him that she has been his mother for the purposes of the novel (27), or when Christie complains that the novel contains too many exclamation marks (166). Johnson also frequently emphasizes the written, and thereby invented, nature of the text. Following Malry's poisoning of a reservoir, Johnson writes: A total of just over twenty thousand people died of cyanide poisoning that morning. This was the first figure that came to hand as it is roughly the number of words of which the novel consists so far. Be assured there are not many more, neither deaths nor words. (147) Johnson introduces himself as a character near the novel's end, apologising to Christie that he won't be able to continue the book much further—to which Christie replies that people don't equate length with importance, and that readers no longer want long novels (165), with the novel being just over 20,000 words long. Johnson delays his description of Christie until the sixth chapter, where he provides a description "with diffidence," fearing that the reader will simply ignore it, or disagree: What writer can compete with the reader's imagination! Christie is therefore an average shape, height, weight, build, and colour. Make him what you will: probably in the image of yourself. You are allowed complete freedom in the matter of warts and moles; as long as he has at least one of either. (51) ==Reception==
