We Must Have Certainty

Book excerpt: We Must Have Certainty surveys the development of the genre of the detective story from its origins in the mid-nineteenth century to its current profile in the early twenty-first century. It locates a principal appeal of the genre in the nature of the world that the detective necessarily inhabits: a world of more or less realistic violence and excitement and, at the same time, a world that always, in the end, makes sense. It suggests that there is a significance to a popular narrative formula that requires that an initial world of suspicion and uncertainty be inevitably transformed by the detective into a world of clarity and order. Though scholarship in the field is acknowledged, the author's citations are most often from detective stories themselves. The essays are written in an accessible style; those who have read a few novels in the genre, as well as those who have read many, will find the book stimulating and provocative.
