The same remark applies to Bulwer's "Strange Story"; it is the strangeness that is the thing. There is, in short, an inalienable charm in the mere contemplation of mystery and the hazard of fortunes; and it would be a pity to shut them out from our consideration only because there is no second-sighted conjurer on hand to turn them into plain matter of fact.

Yet we must not be too liberal; and a ghost story can be brought into our charmed and charming circle only if we have made up our minds to believe in the ghosts; otherwise their introduction would not be a square deal. It would not be fair, in other words, to propose a conundrum on a basis of ostensible materialism, and then, when no other key would fit, to palm off a disembodied spirit on us. Tell me beforehand that your scenario is to include both worlds, and I have no objection to make; I simply attune my mind to the more extensive scope. But I rebel at an unheralded ghostland, and declare frankly that your tale is incredible. And I must confess that I would as lief have ghosts kept out altogether; their stories make a very good library in themselves, and have no need to tag themselves on to what is really another department of fiction. Nevertheless, when a ghost story is told with the consummate art of a Miss Wilkins, and of one or two others on our list, consistency in this regard ceases to be a jewel; art proves irresistible. As for adventure stories, there is a fringe of them that comes under the riddle-story head; but for the most part the riddle story begins after the adventures have finished. We are to contemplate a condition, not to watch the events that ultimate in it. Our detective, or anyone else, may of course meet with haps and mishaps on his way to the solution of his puzzle; but an astute writer will not color such incidents too vividly, lest he risk forfeiting our preoccupation with the problem that we came forth for to study. In a word, One thing at a time!

The foregoing disquisition may seem uncalled for by such rigid moralists as have made up their minds not to regard detective, or riddle stories, as any part of respectable literature at all. With that sect, I announce at the outset that I am entirely out of sympathy. It is not needed to compare "The Gold Bug" with "Paradise Lost"; nobody denies the superior literary stature of the latter, although, as the Oxford Senior Wrangler objected, "What does it prove?" But I appeal to Emerson, who, in his poem of "The Mountain and the Squirrel," states the nub of the argument, with incomparable felicity, as follows:—you will recall that the two protagonists had a difference, originating in the fact that the former called the latter "Little Prig." Bun made a very sprightly retort, summing up to this effect:—

     "Talents differ; all is well and wisely put;
      If I cannot carry forests on my back,
      Neither can you crack a nut."

Andes and Paradises Lost are expedient and perhaps necessary in their proper atmosphere and function; but Squirrels and Gold Bugs are indispensable in our daily walk. There is as fine and as true literature in Poe's Tales as in Milton's epics; only the elevation and dimensions differ. But I would rather live in a world that possessed only literature of the Poe caliber, than shiver in one echoing solely the strains of the Miltonian muse. Mere human beings are not constructed to stand all day a-tiptoe on the misty mountain tops; they like to walk the streets most of the time and sit in easy chairs. And writings that picture the human mind and nature, in true colors and in artistic proportions, are literature, and nobody has any business to pooh-pooh them. In fact, I feel as if I were knocking down a man of straw. I look in vain for any genuine resistance. Of course "The Gold Bug" is literature; of course any other story of mystery and puzzle is also literature, provided it is as good as "The Gold Bug,"—or I will say, since that standard has never since been quite attained, provided it is a half or a tenth as good. It is goldsmith's work; it is Chinese carving; it is Daedalian; it is fine. It is the product of the ingenuity lobe of the human brain working and expatiating in freedom. It is art; not spiritual or transcendental art, but solid art, to be felt and experienced. You may examine it at your leisure, it will be always ready for you; you need not fast or watch your arms overnight in order to understand it. Look at the nice setting of the mortises; mark how the cover fits; how smooth is the working of that spring drawer. Observe that this bit of carving, which seemed mere ornament, is really a vital part of the mechanism. Note, moreover, how balanced and symmetrical the whole design is, with what economy and foresight every part is fashioned. It is not only an ingenious structure, it is a handsome bit of furniture, and will materially improve the looks of the empty chambers, or disorderly or ungainly chambers that you carry under your crown. Or if it happen that these apartments are noble in decoration and proportions, then this captivating little object will find a suitable place in some spare nook or other, and will rest or entertain eyes too long focused on the severely sublime and beautiful. I need not, however, rely upon abstract argument to support my contention. Many of the best writers of all time have used their skill in the inverted form of story telling, as a glance at our table of contents will show; and many of their tales depend for their effect as much on character and atmosphere as on the play and complication of events.

The statement that a good detective or riddle story is good in art is supported by the fact that the supply of really good ones is relatively small, while the number of writers who would write good ones if they could, and who have tried and failed to write them, is past computation. And one reason probably is that such stories, for their success, must depend primarily upon structure—a sound and perfect plot—which is one of the rare things in our contemporary fiction.
