on Inspector Stanislaus Oates and Charlie Luke. After the departure of Captain Hastings, Agatha Christie’s Poirot made something of a confidant of Chief Inspector Japp, but otherwise both he and Miss Marple preferred to work in isolation, their reticence broken only by their occasional enigmatic hints and comments. One rule was brilliantly broken by AgathaChristie, arch-breaker of rules, in her long-running play
The Mousetrap
. She perpetrated an even more audacious deception on the reader in
The Murder of Roger Ackroyd
, where the narrator proves to be the murderer, an ingenious if defensible defiance of all the rules, and although she provided perfectly fair clues, some readers have never forgiven her. The prohibition against Chinamen is difficult to understand. Or was it perhaps the general view that Chinamen, if inclined to murder, would be so clever and cunning in their villainy that the famous detective would be unfairly hampered in his investigation? It is possible that Monsignor Knox was obliquely referring to Dr. Fu Manchu, that oriental genius of crime created by Sax Rohmer, who for nearly fifty years between 1912 and 1959 pursued his evil purposes while no doubt contributing to racial prejudice and fear of the menacing Yellow Peril.
The first rule is interesting. Certainly a proper regard to structure and balance would suggest that the murderer should make an appearance comparatively early in the story, but a demand that this should be no later than two-thirds of the way through the narrative seems unduly restrictive. Some novelists like to begin either with a murder or with the discovery of the body, anexciting and shocking beginning that not only sets the mood of the novel but involves the reader immediately in drama and action. Although I have used this method with some of my novels, I have more commonly chosen to defer the crime and begin by establishing the setting and by introducing my readers to the victim, the murderer, the suspects, and the life of the community in which the murder will take place. This has the advantage that the setting can be described with more leisure than is practicable once the action is under way, and that many of the facts about the suspects and their possible motives are known and do not have to be revealed at length during the course of the investigation. Deferring the actual murder, apart from the build-up of tension, also ensures that the reader is in possession of more information than is the detective when he arrives at the scene. It is an inviolable rule that the detective should never know more than the reader, but there is no injunction against the reader knowing more than the detective—including, of course, when a particular suspect is lying.
With his rule that the reader should not be allowed to follow the murderer’s thoughts, Mon-signor Knox raises one of the main problems in writing mystery fiction. In an introduction to ananthology of short stories published in 1928, Dorothy L. Sayers confronted this difficulty, which still challenges detective novelists today. Miss Sayers did nothing in her life by halves. Having decided to earn some much-needed money by writing detective fiction, she applied her mind to the history, technique and possibilities of the genre. Being highly intelligent, opinionated and combative, she had no hesitation in giving other people the advantage of her views. Not surprisingly, it is Sayers to whom we frequently look for an expert view on the problems and challenges of writing detective fiction in the Golden Age. She wrote:
It does not—and by hypothesis never can—attain the loftiest level of literary achievement. Though it deals with the most desperate effects of rage, jealousy and revenge, it rarely touches the heights and depths of human passion. It presents us only with a
fait accompli
and looks upon death and mutilation with a dispassionate eye. It does not show us the inner workings of the murderer’s mind; it must not, for the
