In so far as Poe had any predecessor in the composing of a narrative, the interest of which should reside in the application of human intelligence to the solution of a mystery, this was not Balzac,—altho the American romancer was sufficiently familiar with the 'Human Comedy' to venture quotation from it. Nor was this predecessor Cooper, whom Balzac admired and even imitated, altho Leatherstocking in tracking his redskin enemies revealed the tense observation and the faculty of deduction with which Poe was to endow his Dupin. The only predecessor with a good claim to be considered a progenitor is Voltaire, in whose 'Zadig' we can find the method which Poe was to apply more elaborately. The Goncourts perceived this descent of Poe from Voltaire when they recorded in their 'Journal' that the strange tales of the American poet seemed to them to belong to "a new literature, the literature of the twentieth century, scientifically miraculous story-telling by A + B, a literature at once monomaniac and mathematical, Zadig as district-attorney, Cyrano de Bergerac as a pupil of Arago."
Voltaire tells us that Zadig by study gained "a sagacity which discovered to him a thousand differences where other men saw only uniformity"; and he describes a misadventure which befell Zadig when he was living in the kingdom of Babylon. One day the chief eunuch asked if he had seen the queen's dog. "It's a female, isn't it?" returned Zadig; "a spaniel, and very small; she littered not long ago; she is lame of the left forefoot; and she has very long ears." "So you have seen her?" cried the eunuch. "No," Zadig answered; "I have never seen her; and I never even knew that the queen had a dog."
About the same time the handsomest horse in the king's stables escaped; and the chief huntsman, meeting Zadig, inquired if he had not seen the animal. And Zadig responded: "It is the horse that gallops the best; he is five feet high; his shoe is very small; his tail is three and a half feet long; the knobs of his bit are of twenty-three-carat gold; and he is shod with eleven-penny silver." And the chief huntsman asked, "Which way did he go?" To which Zadig replied: "I have not seen him; and I have never heard anything about him."
The chief eunuch and the chief huntsman naturally believed that Zadig had stolen the queen's dog and the king's horse; so they had him arrested and condemned, first to the knout, and afterward to exile for life in Siberia. And then both the missing animals were recovered; so Zadig was allowed to plead his case. He swore that he had never seen either the dog of the queen or the horse of the king. This is what had happened: He had been walking toward a little wood and he had seen on the sand the track of an animal, and he judged that it had been a dog. Little furrows scratched in the low hillocks of sand between the footprints showed him that it was a female whose teats were pendent, and who therefore must have littered recently. As the sand was less deeply marked by one foot than by the three others, he had perceived the queen's dog to be lame.
As for the larger quadruped, Zadig, while walking in a narrow path in the wood, had seen the prints of a horse's shoes, all at an equal distance; and he had said to himself that here was a steed with a perfect stride. The path was narrow, being only seven feet wide, and here and there the dust had been flicked from the trees on either hand, and so Zadig had made sure that the horse had a tail three and a half feet long. The branches crossed over the path at the height of five feet, and as leaves had been broken off, the observer had decided that the horse was just five feet high. As to the bit, this must be of gold, since the horse had rubbed it against a stone, which Zadig had recognized as a touchstone and on which he had assayed the trace of precious metal. And from the marks left by the horse's shoes on another kind of stone Zadig had felt certain that they were made of eleven-penny silver.
Huxley has pointed out that the method of Zadig is the method which has made possible the incessant scientific discovery of the last century. It is the method of Wellington at Assaye, assuming that there must be a ford at a certain place on the river, because there was a village on each side. It is the method of Grant at Vicksburg, examining the knapsacks of the Confederate soldiers slain in a sortie to see if these contained rations, which would show that the garrison was seeking to break out because the place was untenable. It is also the method of Poe in the 'Gold-Bug' and in the 'Murders of the Rue Morgue.' In all probability Poe borrowed it directly from Voltaire, who had taken it over from Oriental folklore.
In his application of this method, not casually, playfully, and with satiric intent, as Voltaire had applied it, but seriously and taking it as the mainspring of his story, Poe added an ingenious improvement of his own devising. Upon the preternaturally acute observer who was to control the machinery of the tale, the American poet bestowed a companion of only an average alertness and keenness; and to this commonplace companion the romancer confided the telling of the story. By this seemingly simple device Poe doubled the effectiveness of his work, because this unobservant and unimaginative narrator of the unraveling of a tangled skein by an observant and imaginative analyst naturally recorded his own admiration and astonishment as the wonder was wrought before his eyes, so that the admiration and astonishment were transmitted directly and suggestively, to the readers of the narrative.
In the 'Gold-Bug' the wonder-worker is Legrand, and in both the 'Murders in the Rue Morgue' and the 'Purloined Letter' he is M. Dupin; and in all three tales the telling of the story is entrusted to an anonymous narrator, serving not only as a sort of Greek chorus to hint to the spectators the emotions they ought to feel, but also as the describer of the personality and peculiarities of Legrand and Dupin, who are thus individualized, humanized, and related to the real world. If they had not been accepted by the narrator as actual beings of flesh and blood, they might otherwise retain the thinness and the dryness of disembodied intelligences working in a vacuum.
This device of the transmitting narrator is indisputably valuable; and, properly enough, it reappears in the one series of detective tales which may be thought by some to rival Poe's. The alluring record of the investigations of Mr. Sherlock Holmes is the work of a certain Dr. Watson, a human being but little more clearly characterized than the anonymous narrators who have preserved for us the memory of Legrand and Dupin. But Poe here again exhibited a more artistic reserve than any of his imitators, in so far as he refrained from the undue laudation of the strange intellectual feats which are the central interest of these three tales. In the 'Gold-Bug' he even heightens his suspense by allowing the narrator to suggest that Legrand might be of unsound mind; and in the 'Murders in the Rue Morgue' the narrator, altho lost in astonishment at the acuteness of Dupin, never permits his admiration to become fulsome; he holds himself in, as tho fearing that overpraise might provoke a denial. Moreover, Poe refrained from all exhibitions of Dupin's skill merely for its own sake—exhibitions only dazzling the spectators and not furthering his immediate purpose.
Nothing could be franker than Sir Conan Doyle's acknowledgment of his indebtedness. "Edgar Allen Poe, who, in his carelessly prodigal fashion, threw out the seeds from which so many of our present forms of literature have sprung, was the father of the detective tale, and covered its limits so completely that I fail to see how his followers can find any fresh ground which they can confidently call their own. For the secret of the thinness and also of the intensity of the detective-story is that the writer is left with only one quality, that of intellectual acuteness, with which to endow his hero. Everything else is outside the picture and weakens the effect. The problem and its solution must form the theme, and the character drawing is limited and subordinate. On this narrow path the writer must walk, and he sees the footmarks of Poe always in front of him. He is happy if he ever finds the means of breaking away and striking out on some little side-track of his own."
The deviser of the adventures of Sherlock Holmes hit on a happy phrase when he declared that "the problem and its solution must form the theme." This principle was violated by Dumas, in the 'Vicomte de Bragelonne,' giving us the solution before the problem, when he showed how d'Artagnan used the method of Zadig to deduce all the details of the duel on horseback, after the author had himself described to us the incidents of that fight. But when he was thus discounting his effect Dumas probably had in mind, not Poe, but Cooper, whose observant redskins he mightily admired and whom he frankly imitated in the 'Mohicans of Paris.'
