This book belongs to an unusual genre that might well§be called §personal criticism, sharing as it does§characteristics of both literary §criticism and the personal essay. It is an§exploration of detective §fiction, investigating why I like certain mystery§writers (or not) and §trying to detect whether there is more artistic merit§in their writing §than simply proficient plotting and energetic action.§ The first essay is a §general inquiry into the thriller/detective genre,§looking at various §authors and why I either like or dislike them; the§second considers §three classic writers of the so-called noir mystery§(Dashiell Hammett, §Raymond Chandler, and Ross Macdonald); and the third§examines a §characteristic that many hard-boiled detectives§display, namely, that §each has been damaged in some way, either socially or§psychologically. §The thrust of these essays is not simply to display§my taste but to §discern as well whether and what kinds of literary§merit is to be found §in the writers I consider.
