Detective fiction and true crime books are largely a 20th century invention (albeit one for whom such earlier authors as Poe and Wilkie Collins paved the way). An essay from Erle Stanley Gardner, pulp fiction writer extraordinaire and creator of defense attorney Perry Mason, explains that allure:The mystery book is the answer of modern times to the problems of modern times... The busy executive can't simply forget his problems. They are too pressing, too urgent and too intimate. The only answer is to find something else which will fully occupy the mind. The ordinary novel simply doesn't have the power, the punch, the action. That's why the sale of sleeping tablets and of mystery stories have multiplied to astronomical proportions during the last twenty-five years.
These days most people seem to get their fix from CSI, SUV and all of those other alphabet soup investigation shows. But the principle is the same. And I recall reading that such crime shows exploded in direct response to new standards introduced to control the amount of sex on television. (But, following the well-established model of pulp fiction, these shows cleverly mix sex and violence to attract their huge audiences.)
As for me, I prefer reading about and sometimes even researching crimes to watching them dramatized on the small screen. (Preview: Stay tuned for another true crime post about the James-Younger gang!)
