The detective story for a variety of reasons can seldom be promoted. It is usually about murder and hence lacks the element of uplift. Murder, which is a frustration of the individual and hence a frustration of the race, may have, and in fact has, a good deal of sociological implication. But it has been going on too long for it to be news. If the mystery novel is at all realistic (which it very seldom is) it is written in a certain spirit of detachment; otherwise nobody but a psychopath would want to write it or read it. The murder novel has also a depressing way of minding its own business, solving its own problems and answering its own questions. There is nothing left to discuss, except whether it was well enough written to be good fiction, and the people who make up the half-million sales wouldn’t know that anyway. The detection of quality in writing is difficult enough even for those who make a career of the job, without paying too much attention to the matter of advance sales.
The detective story (perhaps I had better call it that, since the English formula still dominates the trade) has to find its public by a slow process of distillation. That it does do this, and holds on thereafter with such tenacity, is a fact; the reasons for it are a study for more patient minds than mine. Nor is it any part of my thesis to maintain that it is a vital and significant form of art. There are no vital and significant forms of art; there is only art, and precious little of that. The growth of populations has in no way increased the amount; it has merely increased the adeptness with which substitutes can be produced and packaged.
Yet the detective story, even in its most conventional form, is difficult to write well.
